The bite force of Deinosuchus has been estimated to be 18,000 N (1,835 kgf; 4,047 lbf) [8] to 102,803 N (10,483 kgf; 23,111 lbf). [19] Deinosuchus had a secondary bony palate, which would have permitted it to breathe through its nostrils while the rest of the head remained submerged underwater. [20]
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 ...
The evidence of the forested environment is overwhelmingly supported by petrified wood, rooted gley paleosols, [123] and ubiquitous tree leaves. The presence of the simple and lobed leaves, combined with an extremely high dicot diversity, extinct cycadeoid Nilssoniocladus , Ginkgo , many types of monocots , and several types of conifers is ...
[113] [114] Debate on megafaunal extinction in Australia has historically centred on whether the extinctions were caused by humans (which most sources estimate arrived in Australia at least 50,000 years ago, spreading to Tasmania later around 42-41,000 years ago [115]), or whether many megafauna species had already gone extinct prior to human ...
English: A comparison of several size estimates for Deinosuchus, a giant Late Cretaceous crocodilian. The largest credible specimen of modern C. porosus (saltwater crocodile) is also included in the diagram for comparison, as is an average height human.

A Deinosuchus reaches its head out of the sea and grabs one of the Nyctosaurus. Nigel sees another Deinosuchus swimming from the sea up a river, and decides to head in that direction. In the park, Susanne visits Martha the mammoth, who tries to be an "auntie" to the elephant herd's matriarch's calf, but the frightened matriarch drives Martha away.
Deinonychus (/ d aɪ ˈ n ɒ n ɪ k ə s / [1] dy-NON-ih-kəs; from Ancient Greek δεινός (deinós) 'terrible' and ὄνυξ (ónux), genitive ὄνυχος (ónukhos) 'claw') is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus.
[123] [124] While this was occurring, modern birds were undergoing diversification; traditionally it was thought that they replaced archaic birds and pterosaur groups, possibly due to direct competition, or they simply filled empty niches, [92] [125] [126] but there is no correlation between pterosaur and avian diversities that are conclusive ...
