"Titanosaurus" colberti - This species was the most well-known species of Titanosaurus, but has been moved into its own genus, Isisaurus. [14] [15] "Titanosaurus" australis - Known from relatively complete remains, but has been renamed Neuquensaurus. [14] "Titanosaurus" nanus - A small species found to be non diagnostic, and hence a nomen ...
Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan, had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus, had a body mass of approximately 900 kilograms (2,000 lb).
Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina.
A braincase referrable to the species is known from the Pab Formation of Pakistan, which is equivalent in age to the Lameta Formation. [4] Isisaurus is known from better remains than many other titanosaurs that were known at the time of its description. Much of its postcranial skeleton is known. The skeletal material found by Jain and ...
Alamosaurus (/ ˌ æ l əm oʊ ˈ s ɔːr ə s /; [1] meaning "Ojo Alamo lizard") is a genus of titanosaurian sauropod dinosaurs containing a single known species, Alamosaurus sanjuanensis, from the Maastrichtian age of the Late Cretaceous period in what is now southwestern North America.
The type and only species is Volgatitan simbirskiensis, known from seven caudal vertebrae from a single individual. It is the oldest known titanosaur from the northern hemisphere, and is considered important for being related to the Lognkosauria , a group known only from South America later in the Late Cretaceous . [ 1 ]
The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum, which was first announced in 2014 and then named in 2017 by José Carballido and colleagues. Preliminary studies and press releases suggested that Patagotitan was the largest known titanosaur and land animal overall, with an estimated ...
In 1992 Powell validly named Neuquensaurus, with as type species Titanosaurus australis of which the combinatio nova then is Neuquensaurus australis. He also found Titanosaurus robustus to be assignable to the new genus, but considered it non-diagnostical, and so a nomen dubium. [5]
