Sarcosuchus (/ ˌ s ɑːr k oʊ ˈ s uː k ə s /; lit. ' flesh crocodile ') is an extinct genus of crocodyliform and distant relative of living crocodilians that lived during the Early Cretaceous, from the late Hauterivian to the early Albian, 133 to 112 million years ago of what is now Africa and South America.
Schwimmer (2002) suggested the very largest individuals of D. riograndensis could reach sizes up to 12 meters (39 ft), 1.5 times that of the average D. rugosus, based on isometrically scaling vertebral lengths from the type specimens of "Phobosuchus riograndensis" (AMNH 3073) and Deinosuchus hatcheri, which he estimated would represent animals ...
Rhamphosuchus crassidens jaws An 1868 illustration of specimens of R. crassidens (top and center) compared to other crocodylian fossils from the Sewalik Hills. Historically, many palaeontologists estimated that it was one of the largest, if not the largest crocodylian that ever lived, reaching an estimated length of 15 to 18 m (49 to 59 ft). [2]
The prehistoric Australian megalania (Varanus priscus), which may have existed up to 40,000 years ago, is the largest terrestrial lizard known to exist, but the lack of a complete skeleton has resulted in a wide range of size estimates. Molnar's 2004 assessment resulted in an average weight of 320 kg (710 lb) and length of 4.5 m (15 ft), and a ...
A pair of researchers with the University of Iowa decided to re-examine existing fossils of the Deinosuchus, a prehistoric ancestor of crocodiles and alligators estimated to be about 33-feet-long ...
One of the largest of prehistoric otariids is Thalassoleon, comparable in size to the biggest extant fur seals. An estimated weight of T. mexicanus is no less than 295–318 kg (650–701 lb). [154] The biggest known mustelid to ever exist was likely the giant otter, Enhydriodon. It exceeded 3 m (9.8 ft) in length, and would have weighed in at ...
The discovery of a prehistoric crocodile fossil in Peru from around 7 million years ago has given paleontologists more clues as to how modern crocodiles, all freshwater creatures in the Andean ...
Crocodylus thorbjarnarsoni likely preyed on hominids like Paranthropus and early members of the genus Homo, both of which are known from the Turkana Basin.Direct evidence of crocodilian predation is known from bite marks on hominin bones from the Olduvai Gorge, and these marks were likely made by the closely related crocodile C. anthropophagus [citation needed] (anthropophagus means "human ...
