One study indicated Deinosuchus may have lived for up to 50 years, growing at a rate similar to that of modern crocodilians, but maintaining this growth over a much longer time. Deinosuchus fossils have been discovered in 12 U.S. states, including Texas, Montana, and many along the East Coast. Fossils have also been found in northern Mexico.
Deinosuchus is an extinct genus related to the alligator that lived 80 to 73 million years ago , during the late Cretaceous period. The name translates as "terrible ...
English: A comparison of several size estimates for Deinosuchus, a giant Late Cretaceous crocodilian.

Life restoration of Sarcosuchus imperator. Sarcosuchus is a distant relative of living crocodilians, with fully grown individuals estimated to have reached up to 9 to 9.5 m (29.5 to 31.2 ft) in total length and 3.45 to 4.3 metric tons (3.80 to 4.74 short tons) in weight. [2]
They are currently the most successful and diverse group of living reptiles, with more than 10,000 extant species. The only major group of terrestrial lizards to go extinct at the end of the Cretaceous were the polyglyphanodontians, a diverse group of mainly herbivorous lizards known predominantly from the Northern Hemisphere.

Remains of a giant, human-sized heron species, thought to have gone extinct around 1500 BC, were discovered in the United Arab Emirates in 1977. [ 4 ] [ 5 ] It lived on the Arabian Peninsula and shared many characteristics with Bennu, and scientists believe it may have been the animal model for the deity.
Prehistoric religion is the religious practice of prehistoric cultures. Prehistory, the period before written records, makes up the bulk of human experience; over 99% of human experience occurred during the Paleolithic period alone.
Suchomimus itself was more adapted to a life hunting in shallow water due to its hollow bones, while Baryonyx and Spinosaurus were capable of fully submerging underwater and diving after prey. Courtesy of denser bones, the latter two spinosaurids could hunt underwater for prey and occupy a more derived lifestyle than Suchomimus could.
