T-rex was specialized in taking down prey like edmontosaurus or Triceratops. [13][23] Even relatively closely related titanosaurs could have very different body sizes, as the small rinconsaurs were closely related to the gigantic lognkosaurs.

Similar to Upchurch (1995), Sanz et al. [2], Because of their incomplete preservation, the original position of the known dorsal vertebrae within the vertebral column is disputed. Language links are at the top of the page across from the title. Their teeth were either somewhat spatulate (spoon-like) or like pegs or pencils, but were always very small. Spinosaurus was a fish eater. Show more ARK: Survival Evolved 2015 Browse game. . Though not as strongly deformed as the complete femur, it preserves only the shaft and lacks its upper and lower ends. [67] Further updates and modifications were then made by Palbo Gallina & Apestegua 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. The species was first described in 1980, and it is considered small compared with other titanosaur species, measuring only 12.2 to 12.8 meters (about 40 to 42 feet) long and weighing slightly under 7 metric tons (about 7.7 tons). [58], In 1997, Leonardo Salgado et al. published a phylogenetic study on Titanosauriformes, including relationships within Titanosauria. And Amphicoelias is. Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina. [5] As of 2019, however, it was still uncertain whether any of these femora belonged to Argentinosaurus. However, this didn't mean that sauropods as a whole were destined for early . While several other titanosaurs relied on their sheer size to dissuade predators from attacking them, an analysis of a collection of incomplete fossil skeletons of Saltasaurus suggests that the species employed a different defensive strategy. (1999) and modifying it to include additional taxa and some character changes, Powell found that titanosaurs formed mostly a single gradual radiation beginning with Epachthosaurus as the most basal titanosaur, and Ampelosaurus and Isisaurus as the most derived. The only difference in the resulting phylogeny, based on the matrix of the Calvo, Gonzlez-Riga & Porfiri (2007), was the addition of Futalognkosaurus as the sister taxon to Mendozasaurus in a clade Calvo et al. [13] In 2013, William Sellers and colleagues arrived at a length estimate of 39.7 metres (130ft) and a shoulder height of 7.3 metres (24ft) by measuring the skeletal mount in Museo Carmen Funes. [16] In others, such as Rapetosaurus and Nemegtosaurus, the head resembled that of diplodocids. There have been many previous contenders for the title "world's biggest dinosaur". [28], 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.
