Extinct crocodylomorphs were considerably more ecologically diverse than modern crocodillians. The earliest and most primitive crocodylomorphs are represented by "sphenosuchians", a paraphyletic assemblage containing small-bodied, slender forms with elongated limbs that walked upright, which represents the ancestral morphology of Crocodylomorpha.
†Paleorhinus sawini – type locality for species †Paluxysaurus – type locality for genus. Now regarded as a junior synonym of Sauroposeidon. [citation needed] †Paluxysaurus jonesi – type locality for species. Now regarded as a junior synonym of Sauroposeidon proteles. [citation needed]
In 1938, a major dinosaur footprint find occurred near Glen Rose. Pleurocoelus was the Texas state dinosaur from 1997 to 2009, when it was replaced by Sauroposeidon (Paluxysaurus jonesi) after the Texan fossils once referred to the former species were reclassified to a new genus.
Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...
Nile crocodile ambushing migrating wildebeest crossing the Mara River. Crocodilians are largely carnivorous. The diets of species varies with snout shape and tooth sharpness. Species with sharp teeth and long, slender snouts, like the Indian gharial and Australian freshwater crocodile, are specialized for snapping fish, insects, and crustaceans.
There were duck-billed dinosaurs, horned dinosaurs, armored dinosaurs, meat-eating dinosaurs, and various crocs, turtles, small mammals, birds, amphibians and fish.
The bigger, but less common, Deinosuchus that lived in Texas and Montana might have been more specialized hunters, capturing and eating large dinosaurs. [17] Schwimmer noted no theropod dinosaurs in Deinosuchus 's eastern range approached its size, indicating the massive crocodilian could have been the region's apex predator .
A Brazilian scientist has identified fossils of a small crocodile-like reptile that lived during the Triassic Period several million years before the first dinosaurs. The fossils of the predator ...
