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.
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 only order-level taxon that is currently considered valid is Crocodilia in its present definition. Prehistoric crocodiles are represented by many taxa, but since few major groups of the ancient forms are distinguishable, a conclusion on how to define new order-level clades is not yet possible. (Benson & Clark, 1988).
Crocodiles with teeth the size of bananas were apparently a nightmare that actually existed during the Late Cretaceous period. ... a prehistoric ancestor of crocodiles and alligators estimated to ...
Skull of E. mirabilis. Estemmenosuchus could reach a body length of more than 3 m (10 ft). [2] Its skull was long and massive, up to 65 cm (26 in) in length, [2] and possessed several sets of large horns, somewhat similar to the antlers of a moose, growing upward and outward from the sides and top of the head.
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 ...
Terminonaris was a predator that could reach a length of about 6 m (19.7 ft). [1] The skull of the largest individual is 98.3 cm (38.7 in) long. [1] The elongated snout and the long, relatively thin teeth suggest that Terminonaris was a hunter of fish, small mammals and possibly small dinosaurs.
The American Museum of Natural History incorporated the skull and jaw fragments into a plaster restoration, modeled after the present-day Cuban crocodile. Colbert and Bird stated this was a "conservative" reconstruction, since an even greater length could have been obtained if a long-skulled modern species, such as the saltwater crocodile had ...
