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.
This is a list of dinosaurs whose remains have been recovered from Appalachia.During the Late Cretaceous period, the Western Interior Seaway divided the continent of North America into two landmasses; one in the west named Laramidia and Appalachia in the east.
Deinosuchus, [134] being one of the largest crocodilians of the fossil record, [135] was an apex predator that did prey on the dinosaurs [136] [137] [138] in the area, the same case applies for Laramidia as well, [139] [140] despite the fact that the majority of its diet consisted of turtles [141] and sea turtles.
"Deinosuchus was a giant that must have terrorized dinosaurs that came to the water's edge to drink," study lead Dr. Adam Cossette said in a press release.
"Microcephale": Said to be an extremely small pachycephalosaur, with skull caps only 5 centimetres (2.0 in) long. Mojoceratops perifania : May be a synonym of Chasmosaurus . Nanotyrannus lancensis : Most likely a juvenile Tyrannosaurus , although a more recent study suggests it might be a possibly distinct taxon based on referred specimens.
P. kirkpatricki compared to a human. Postosuchus was one of the largest carnivorous reptiles during the late Triassic. The length of the paratype is estimated up to 3.5–4 m (11–13 ft) long, [3] and an individual of such length would have measured 2 metres (6.6 ft) tall at the head when stood upright and weighed around 250–300 kilograms (550–660 lb).

The advent of agriculture roughly 11,500 years ago in the Middle East was a milestone for humankind - a revolution in diet and lifestyle that moved beyond the way hunter-gatherers had existed ...
American palaeontologist Thomas Holtz noted that spinosaurid teeth were adapted for grasping rather than slicing, hence their reduced serrations, which in most other theropods were more prominent. Suchomimus 's extensive secondary palate, which would have made the roof of the mouth more solid, allowed it to better resist twisting forces exerted ...
