DGM Serie B"), Contributing additional work to the systematics of titanosaurs, Spanish paleontologist José Sanz et al. Aeolosaurus, Alamosaurus, Ampelosaurus and Magyarosaurus were looked at using their character list, but were considered too incomplete to add to the final study. [49] Further updates and modifications were then made by Palbo Gallina & Apesteguía in 2011, with the additions of Ligabuesaurus, Antarctosaurus, Nemegtosaurus and Bonitasaura and character updates to match, bringing the total to 77 characters and 22 taxa. One of the few areas of agreement is that the majority of titanosaurs except Andesaurus and some other basal species form a clade called Lithostrotia, which some researchers consider equivalent to the deprecated Titanosauridae. They differed from other sauropods, however, in that the titanosaurs’ bodies were stockier and their limbs produced a wider stance than other sauropods. Size is and has been one of the most fascinating aspects of dinosaur paleontology, to both the general public and professional scientists.Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds, which can weigh as little as three grams, to the extinct titanosaurs, which could weigh as much as 80 t (88 short tons). Please refer to the appropriate style manual or other sources if you have any questions. Their forelimbs were also stocky, and often longer than their hind limbs. Let us know if you have suggestions to improve this article (requires login). [43], American paleontologist Jeff Wilson presented another revision of overall sauropod phylogeny in 2002, resolving strong support for most groups, and a similar result to Upchurch (1998) although with Euhelopus closest to titanosaurs instead of outside Neosauropoda. published an additional study in 1999, utilizing both the names Titanosauria and Titanosauroidea in displaying their results. For much of the dinosaur era, the smallest sauropods were larger than anything else in their habitat, and the largest were an order of magnitude more massive than anything else that has since walked the Earth. i've always heard it used to reference the largest of the sauropods, multiple species, but not one specific one XD For instance, Argentinosaurus is one of the biggest sauropods, and it is often referred to as a Titanosaur The ĠH 2O of Auca Mahuevo egg is 2.7 times greater than an avian egg of comparable size and the microenvironment of the nest remains unclear. Proposing her analysis as the basis for a new phylogenetic framework of Titanosauria, Curry-Rogers recommended only using named for clades that were very strongly supported. Titanosaurs had small heads, even when compared with other sauropods. Like its relative, Saltasaurus, it had Dragon-like lumpy spikes on its back. Steam Community: ARK: Survival Evolved. 321–345 in Tidwell, V. and Carpenter, K. [58], Philip Mannion and colleagues redescribed Lusotitan in 2013, creating a new analysis of 279 characters drawn from significant previous analyses by Upchurch and Wilson supplemented by other studies. Titanosaur necks were of average length for sauropods, and their tails were whip-like though not as long as in the diplodocids. Titanosaurs also possessed vertebrae with a honeycomb-like internal structure and six sacral vertebrae (vertebrae adjacent to the pelvis), but they lacked the hyposphene-hypantrum joints (which connected one vertebra to another) in their dorsal vertebrae (vertebrae that articulate with the ribs). [19][20] Osteoderms were present on both large and small species, so they were not solely used by smaller species as protection against predators. Eutitanosauria was proposed as a name for the titanosaurs more derived than Epachthosaurus, and noted the presence of osteoderms as a probable synapomorphy of this clade. Fossilized bone fragments found in northwest Patagonia could belong to a new species of super-sized titanosaur, a dinosaur family including some of the largest animals to ever walk on Earth. [2][7] Even relatively closely related titanosaurs could be very different body sizes, as the small rinconsaurs were closely related to the gigantic lognkosaurs. 364 characters were selected from all previous phylogenetic analyses and scored across 29 probable titanosaurs, ranging from the Late Jurassic African Janenschia to the large variety of Late Cretaceous global genera. Using the family Titanosauridae to include them all, he grouped the genera into Titanosaurinae, Saltasaurinae, Antarctosaurinae, Argyrosaurinae and Titanosauridae indet. These are known as “sails.” Although paleontologists originally believed that spinosaurus walked on two legs, new research has suggested that they walked on four legs, at least occ… Their spinal column was relatively flexible, likely making them more agile than other sauropods and more able to rear onto their hind legs. 2004) was defined to be Malawisaurus and all more derived titanosaurs, and the clade Eutitanosauria (Sanz et al. [38], José Bonaparte and Rodolfo Coria in 1993 concluded that a new clade of derived sauropods was necessary because Argentinosaurus, Andesaurus and Epachthosaurus were distinct from Titanosauridae as they possessed hyposphene-hypantrum articulations, but were still very closely related to the titanosaurids. The Titanosaur is a fairly peaceful creature. Titanosaurs hold the world record for the size of a land animal. [33] Following this, Austro-Hungarian paleontologist Franz Nopcsa reviewed reptile genera in 1928, and provided a short classification of Sauropoda, where he placed the Titanosaurinae (a reranking of Lydekker's Titanosauridae) in Morosauridae, and included the genera Titanosaurus, Hypselosaurus and Macrurosaurus because they all had strongly procoelous caudals. Unique to Mannion et al., continuous characters were distinguished in a run of the matrix, which resolved almost all of Somphospondyli within Titanosauria because of Andesaurus placing very basal in a large group of Andesauroidea. in 2009 in a phylogenetic analysis based partially on that of Calvo et al. [25] While the original analysis didn't focus on titanosaurs, it was utilised during the descriptions of Savannasaurus and Diamantinasaurus, Yongjinglong, an osteology of Mendozasaurus, and redescribing Tendaguria. Titanosauroidea was tentatively retained as the opposite clade of titanosaurs, which included all other traditional titanosaurs, although it was noted because of the invalidity of Titanosaurus, Titanosauroidea should be considered an invalid name as well. Although other titanosaurs (such as Patagotitan and Argentinosaurus, whose weights have been estimated at 63.5 metric tons [70 tons] and 70 metric tons [77 tons], respectively) have been conjectured to have been larger than Dreadnoughtus, which was 26 metres (about 85 feet) long and weighed 59 metric tons (65 tons), Dreadnoughtus was the largest titanosaur whose size can be calculated … One question we had is if T-Rex and Titanosaurus had ARK's Titanosaurus size comparison … They provided a definition for the clade of "including the most recent common ancestor of Andesaurus delgadoi and Titanosauridae and all of its descendants". [45][46] For Mendozasaurus, the new genus grouped with Malawisaurus as basal within Titanosauridae, but because of the features of caudal vertebrae in these basal taxa, González-Riga recommended revising the diagnosis of the family, instead of changing the content. This, coupled with the preservation of a single phalanx on digit IV of Epachthosaurus and potentially Opisthocoelicaudia (further study is necessary), show that preservation biases may be responsible for the lack of hand phalanges in these taxa. 1999) was considered a possible synonym of Saltasauridae. [34] German paleontologist Friedrich von Huene provided a significant revision of Titanosauridae the following year in 1929, where he reviewed the dinosaurs of Cretaceous Argentina, and named multiple new genera. The impressions showed that titanosaurs were covered in a mosaic armour of small bead-like scales. The newly identified titanosaur was so immense — 69 tons ... Patagonia, where the dinosaur was found, and "titan" recalls Greek divinities, known for their strength and large size. The head was also wide, similar to the heads of Camarasaurus and Brachiosaurus, though somewhat more elongated. Fossils from perhaps the largest dinosaur ever found were discovered in 2012 in the Neuquén Province of northwest Patagonia, Argentina. Unlike other sauropods, some titanosaurs had no digits, walking only on horseshoe-shaped "stumps" made up of the columnar metacarpal bones. Australia had titanosaurs around 96 million years ago: fossils have been discovered in Queensland of a creature around 25 metres (82 ft) long. Fossilized dung associated with late Cretaceous titanosaurids has revealed phytoliths, silicified plant fragments, that offer clues to a broad, unselective plant diet. This highly diverse group forms the dominant clade of Cretaceous sauropods. The primary focus of the analysis was on the basal titanosauriform taxa, but Titanosauria was defined, as the most recent common ancestor of Andesaurus delgadoi and Saltasaurus loricatus, and all its descendants, although the only autapomorphy of the group recovered was the absence of a prominent ventral process on the scapula. Titanosauroidea (following Upchurch 1995), was distinguished by pre- and post-spinal laminae in anterior caudals, a laterally flared ilium, a lateral expansion of the upper femur, and strongly opisthocoelous posterior dorsals. [24] Titanosaurs are now known to be most closely related to euhelopodids and brachiosaurids; together they form a clade named Titanosauriformes. Alamosaurus and Opisthocoelicaudia were united within Opisthocoelicaudiinae, Neuquensaurus and Saltasaurus formed Saltasaurinae, and Isisaurus placed as the next most derived titanosaurid. Titanosauridae included many previously named genera, plus taxa like Tornieria and Janenschia. published another paper, describing the basal titanosaur Futalognkosaurus. Titanosauridae was less strongly defined because of the polytomy between Malawisaurus and Epachthosaurus, so some diagnostic eatures couldn't be resolved. [29] In the same year, Calvo et al. Opisthocoelicaudia was placed in Opisthocoelicaudiinae within Camarasauridae, following its original description and not later works, and Nemegtosaurus and Quaesitosaurus were placed within Dicraeosaurinae. By comparison, the complete femora preserved in the other giant titanosaurs Antarctosaurus giganteus and Patagotitan mayorum measure 2.35 metres (7.7 ft) and 2.38 metres (7.8 ft), respectively. [63] In an updated version of the analysis, with the taxon Mnyamawamtuka added, Gorscak & O'Connor (2019) got similar results, with slightly different relationships within small clades.[64]. This suggests that Alamosaurus, Neuquensaurus, Saltasaurus and Rapetosaurus - all known from imperfect or disarticulated remains previously associated with a lack of phalanges - may have had phalanges but lost them after death. (2017) published a phylogenetic analysis of Titanosauria including the most taxa of any analysis of the clade. (1997) as Andesaurus plus Saltasaurus. The variety of Romanian fossils named as Magyarosaurus by Huene were also moved into the same species again, M. dacus as originally named by Nopcsa. 1 Summary 2 Powers and Stats 3 Gallery 4 Others TheTitanosaur is one of the Creatures in ARK: Survival Evolved. The Titanosaur is the largest creature in Ark whose stats top the charts across the board. This result places Titanosauroidea in a group with Camarasaurus and Brachiosaurus, although Nemegtosauridae (Nemegtosaurus and Quaesitosaurus) was still classified as the basalmost family of diplodocoids. Titanosauria was additionally rediagnosed, with eye-shaped pleurocoels, forked infradiapophyseal laminae, centro-parapophyseal laminae, procoelous anterior caudals, and a significantly longer pubis than ischium. Nemegtosaurus and Quaesitosaurus were resolved within Titanosauria for the first time, after being placed in Diplodocoidea by multiple other analyses, because Rapetosaurus provided the first significant titanosaur cranial material with associated postcrania. long, but is still dwarfed by ARK's Titanosaurus which is 124.5 meters long. (2007), although Epachthosaurus was nested with Rapetosaurus outside the clades of aeolosaurines. Examination of the titanosaur's bones revealed what appear to be parasitic blood worms similar to the prehistoric Paleoleishmania but are 10-100 times larger, that seemed to have caused the osteomyelitis. Paleontologists have discovered the remains of a dinosaur that lived 98 million years ago in Argentina and could be the biggest dinosaur ever found. [31] While it was later given a position as a sauropod within Cetiosauridae by Lydekker in 1888,[32] he named the new sauropod family Titanosauridae for the genus in 1893, which included only Titanosaurus and Argyrosaurus, united by procoelous caudals, opisthocoelous presacrals, a lack of pleurocoels and open chevrons. Because of their sparse arrangement, it was unlikely that they served a significant role in defense. The group contains the largest terrestrial animals known, some even approaching the size of modern whales. Saltasaurinae and Opisthocoelicaudiinae were retained with their original definitions, but Lithostrotia was considered a synonym of Titanosauridae, and Titanosaurinae was considered a paraphyletic clade of unrelated titanosaurids. [62], In the description of Mansourasaurus, Sallam et al. The most complete set of remains, however, belongs to Dreadnoughtus and includes approximately 70 percent of the dinosaur’s skeleton behind its head. Osteoderms were first confirmed in the genus Saltasaurus but are now known to have been present in a variety of titanosaurs within the clade Lithostrotia. However, their wandering nature causes them to easily deforest an area, which is a mixed blessing. The finding of such complete remains allowed paleontologists to make confident estimates of the dinosaur’s length and weight. Updates? Other taxa like Epachthosaurus show a reduction of phalanges to one or two bones. A large titanosaurid nesting ground was discovered in Auca Mahuevo, in Patagonia, Argentina and another colony has reportedly been discovered in Spain. The titanosaurs, a group of sauropods that included. A comparison of the species of titanosaur known to have been present in Patagonia 100 million years ago. Other information includes an admin spawn command generator, blueprint, name tag and entity class. The newest iteration of my size comparison, In this update i've made several changes to some of the creatures that were in the previous version. Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of sauropod dinosaurs, including genera from Africa, Asia, South America, North America, Europe, Australia and Antarctica. [28], Another form of composite matrix was created by Calvo, González-Riga and Juan Porfiri in 2007, based upon multiple previous studies between 1997 and 2003. Titanosaurian nostrils were large ("macronarian") and all had crests formed by the nasal bones. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. More derived clades, while resolved, were only weakly supported, or characterized by reversions of diagnostic traits of larger groups (below and left). in 2019 for a redescription of Jiangshanosaurus and Dongyangosaurus, and additional revisions of Ruyangosaurus were made. Lognkosauria moved to be within rinconsaurs, while Nemegtosauridae was resolved as the sister of Aeolosaurus and Gondwanatitan, and the rinconsaur-lognkosaur branch. [40], In 1997, Leonardo Salgado et al. The specimen hails from the late cretaceous Adamantina Formation, and was described in October,2020 in the journal Cretaceous Research by Aline Ghilardi et al,. More internal clades were resolved for Titanosauria, with Nemegtosaurus and Rapetosaurus united within Nemegtosauridae, and Saltasauridae including two subfamilies, Opisthocoelicaudiinae and Saltasaurinae. The osteoderms were certainly far more sparse than those of ankylosaurs, and did not completely cover the back in scutes. [12], Wilson and Paul Upchurch followed this study up in 2003 with a significant revision of the type genus Titanosaurus, and revisited all the material that had been assigned to the genus while reviewing titanosaur inter-relationships. The titanosaurians were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. This sauropod, itself a titanosaur, was estimated to be perhaps as long as 39.7 meters. Only the three genera and various intermediate specimens were included in Aeolosaurini in their 2004 paper, with the tribe being considered to be within Saltasaurinae. United by: caudals with anteriorly-shifted neural spines, extremely robust forearm bones, a prominent concavity on the ulna for articulation with the humerus, a laterally flared and flattened ilium, and a less robust pubis; Upchurch considered the clade sister taxon to Diplodocoidea, because of their shared dental anatomy, although he noted that peg-like teeth might have been independently evolved. [52], Also following the 2002 analysis of Wilson, José Carballido and colleagues published a redescription of Chubutisaurus in 2011, and utilized an updated Wilson matrix, expanded to 289 characters across 41 taxa, including 15 titanosaurs. [25], For much of the 20th century, most known species of titanosaurs were classified in the family Titanosauridae, which is no longer in widespread use. [citation needed] The fossil evidence suggests they replaced the other sauropods, like the diplodocids and the brachiosaurids, which died out between the late Jurassic and the mid-Cretaceous Periods. If correct, the fossil would be the first known instance of an aggressive case of osteomyelitis being caused by blood worms in a prehistoric animal. Rinconsauria included taxa typically found within Aeolosaurini as well, so Aeolosaurini was redefined as Aeolosaurus rionegrinus plus Gondwanatitan to preserve the original restricted content, otherwise the entire rinconsaur-lognkosaur branch would be classified within Aeolosaurini. [26][30], In 2005, Curry-Rogers proposed a new phylogenetic analysis that focused on the inter-relationships of Titanosauria and included the most expansive character and taxon list of any study before it. Image demonstrating the recently identified titanosaur’s size in comparison to a female adult and the fossils that were found (in red). [18] Several other arrangements have been proposed, such as a single row along the midline, and it is possible that different species had different arrangements. [47], The second edition of The Dinosauria, published in 2004, included newly described titanosaurs and other taxa reidentified as titanosaurs. Malawisaurus nested with Andesaurus in a clade of the basalmost titanosaurs outside Titanosauroidea, where Lirainosaurus, instead of being the basal member of the saltasaur-branch was instead basalmost titanosauroid. The taxa that possessed the articulations were united within the new family Andesauridae, and the two families were grouped together within the new clade Titanosauria. (2016) rescored the analysis of Zaher et al. The titanosaurs were the last great group of sauropods, which existed from about 136[67] to 66 million years ago, before the Cretaceous–Paleogene extinction event, and were the dominant herbivores of their time. The new clade (defined as Rinconsaurus and Muyelensaurus) was placed as the sister taxon of Aeolosaurini, which together grouped with Rapetosaurus as sister to Saltasauridae. Similar to Upchurch (1995), Sanz et al. The French taxon Aepisaurus was removed from the family and placed in undetermined Sauropoda. The species is known from a femur and two caudal vertebrae found in rocks dating to the Cretaceous in central India. Written by Upchurch, Paul Barrett and Peter Dodson, a review of Sauropoda included a more expansive Titanosauria for sauropods more derived than brachiosaurids. ), CS1 maint: multiple names: authors list (, "A new giant titanosaur sheds light on body mass evolution among sauropod dinosaurs", "A Middle Jurassic dinosaur trackway site from Oxfordshire, UK", "Small body size and extreme cortical bone remodeling indicate phyletic dwarfism in Magyarosaurus dacus (Sauropoda: Titanosauria)", "Massive new dinosaur might be the largest creature to ever roam Earth", "A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria", "Sauropod dinosaur phylogeny: critique and cladistic analysis", "A gigantic new dinosaur from Argentina and the evolution of the sauropod hind foot", "The early evolution of titanosauriform sauropod dinosaurs", "Titanosaur Osteoderms from the Upper Cretaceous of Lo Hueco (Spain) and Their Implications on the Armor of Laurasian Titanosaurs", "Sauropod dinosaur osteoderms from the Late Cretaceous of Madagascar", "The internal anatomy of titanosaur osteoderms from the Upper Cretaceous of Spain is compatible with a role in oogenesis", "Taxonomic affinities of the putative titanosaurs from the Late Jurassic Tendaguru Formation of Tanzania: phylogenetic and biogeographic implications for eusauropod dinosaur evolution", "An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade", "The phylogenetic relationships of sauropod dinosaurs", "Nuevos materiales de Titanosaurios (Sauropoda) en el Cretácico Superior de Mato Grosso, Brazil", "A new Cretaceous terrestrial ecosystem from Gondwana with the description of a new sauropod dinosaur", "Cranial anatomy and phylogenetic position of the titanosaurian sauropod, "A Complete Skull of an Early Cretaceous Sauropod and the Evolution of Advanced Titanosaurians", "Osteology and phylogenetic relationships of, "New Australian sauropods shed light on Cretaceous dinosaur palaeobiogeography", "A New Titanosaurian Sauropod from the Hekou Group (Lower Cretaceous) of the Lanzhou-Minhe Basin, Gansu Province, China", "New information on the Cretaceous sauropod dinosaurs of Zhejiang Province, China: impact on Laurasian titanosauriform phylogeny and biogeography", "A new African Titanosaurian Sauropod Dinosaur from the middle Cretaceous Galula Formation (Mtuka Member), Rukwa Rift Basin, Southwestern Tanzania", "3-D Modelling of Megaloolithid Clutches: Insights about Nest Construction and Dinosaur Behaviour", "Bones reveal Queensland's prehistoric titans", "Bone discovery confirms big dinosaur roamed NZ", "Giant footprint could shed light on titanosaurus behaviour", "Blood parasites and acute osteomyelitis in a non-avian dinosaur (Sauropoda, Titanosauria) from the Upper Cretaceous Adamantina Formation, Bauru Basin, Southeast Brazil", "Gruesome ‘Blood Worms’ Invaded a Dinosaur’s Leg Bone, Fossil Suggests", "Cretaceous Titanosaur Suffered from Blood Parasites and Severe Bone Inflammation | Paleontology | Sci-News.com", "How big is new Field Museum dinosaur? The titanosaurs were diagnosed by possessing small pleurocoels centered within an anteroposteriorly elongate depression and the presence of two well defined depressions on the posterior face of the neural arch. Dinosaur Size Comparison 3D - Smallest to Biggest - YouTube One of the most characteristic features shared by most titanosaurs were their procoelous caudal vertebrae, with ball-and-socket articulations between the vertebral centra. Titanosauria, defined as everything closer to Saltasaurus than Brachiosaurus, included a very large variety of taxa, and the new clade Lithostrotia was named for a large number of more derived taxa, although Nemegtosauridae was placed in Diplodocoidea following earlier publications of Upchurch. One place in the Argentine had 150 bones from seven titanosaurs. Significantly contrasting the earlier results, internal relationships of Titanosauria were rearranged. The entire group was compared favourably with cetiosaurids like Patagosaurus and Volkheimeria. [10] In others, such as Rapetosaurus and Nemegtosaurus, the head resembled that of diplodocids. [27], Overlooking the naming of Titanosauria, Paul Upchurch in 1995 named the clade Titanosauroidea, to include Opisthocoelicaudia and the more derived Titanosauridae (Malawisaurus, Alamosaurus and Saltasaurus). The Ark creature ID for titanosaur with a copyable spawn command. [12], The dorsal vertebrae of titanosaurs show multiple derived features among sauropods. [26][30][29] Lithostrotians include titanosaurs such as Alamosaurus, Isisaurus, Malawisaurus, Rapetosaurus, and Saltasaurus. Even if approached by a survivor on a mount, Titanosaurus is content with roaming the land in search of food. Like other sauropods, titanosaurs were herbivorous quadrupeds with long tails, long necks, and small heads. [30] Lithostrotia adopted the distinguishing feature of strongly procoelous caudals, previously used for Titanosauria. Titanosaurus is the signature member of the family of dinosaurs known as titanosaurs, which were the last sauropods to roam the earth before the K/T Extinction 65 million years ago. (2013), but a large clade of Andesauroidea was still resolved with implied weights. The fossils, of a fragmentary nature, were superficially similar to remains of other sauropods that were initially classified as titanosaurs, and the genus Titanosaurus became a “wastebin taxon”—a group that serves as a placeholder for fossils too indistinct to be classified in other groups. The new genus Epachthosaurus was named for a more basal titanosaurid classified as Titanosauridae indet. Titanosaurinae included Titanosaurus and the new genus Aeolosaurus, united by multiple features of the caudal vertebrae; the new clade Saltasaurinae was created to include Saltasaurus and the new genus Neuquensaurus, united by very distinct dorsals, caudals, and ilia; the new clade Antarctosaurinae was created to include Antarctosaurus, distinguished by large size, a different form of braincase, more elongate girdle bones, and more robust limb bones; and Argyrosaurinae was created for Argyrosaurus, bearing a more robust forelimb and hand and more primitive dorsals. Huene's species Titanosaurus lydekkeri was left as a nomen dubium, but left within Titanosauridae. [45] The situation of caudals in Rinconsaurus also suggested procoelous caudals were no longer diagnostic, because in the tail of Rinconsaurus the vertebrae regularly changed their articular surfaces, being from procoelous caudals interspersed with amphicoelous, opisthocoelous and biconvex vertebrae. Huene included multiple species of Titanosaurus from India, England, France, Romania, Madagascar and Argentina, Hypselosaurus and Aepisaurus from France, Macrurosaurus from England, Alamosaurus from United States, and Argyrosaurus, Antarctosaurus, and Laplatasaurus from Argentina. Doing an elementary paper comparing the size of Titanosaurus to the more commonly known T-Rex. While the pelvis was slimmer than some sauropods, the pectoral (chest) area was much wider, giving them a uniquely "wide-legged" stance. While non-titanosaur phylogeny remained identical in every single result, the topology within Titanosauria was very labile and prone to change with minor adjustments. About Titanosaurus . (eds. Wilson & Upchurch (2003) supported the definition of Salgado et al. Besides the plant remains that might have been expected, such as cycads and conifers, discoveries published in 2005[65] revealed an unexpectedly wide range of monocotyledons, including palms and grasses (Poaceae), including ancestors of rice and bamboo, which has given rise to speculation that herbivorous dinosaurs and grasses co-evolved. Lithostrotia (Upchurch et al. Technical processes were then carried out in Loja and analyses of the results in Buenos Aires . Titanosaurus was a huge titanosaurid sauropod that lived in India, Asia, Argentina and South America. Saltasaurinae was defined as the most recent ancestor of Neuquensaurus, Saltasaurus and its descendants, and diagnosed by short cervical prezygapophyses, vertically compressed anterior caudals, and a posteriorly shifted anterior caudal neural spine.
