Jouve and colleagues suggested in 2008 that juvenile marine crocodyliforms lived in freshwater environments as do modern marine crocodile juveniles, which would have helped them survive where other marine reptiles became extinct; freshwater environments were not so strongly affected by the K–Pg extinction event as marine environments were. [119]
Crocodylomorpha in the modern sense, as defined by Paul Sereno in 2005, is phylogenetically defined as the most inclusive clade containing Crocodylus niloticus (the Nile crocodile), but not Rauisuchus tiradentes, Poposaurus gracilis, Gracilisuchus stipanicicorum, Prestosuchus chiniquensis, or Aetosaurus ferratus.
The first effect on the Earth, after the blast wave and potential multiple fire storms, would be the death of most, if not all, of the photosynthetic life forms on Earth. Those in the ocean that survive would possibly become dormant until the sun came out again.
Ocean-dwelling dyrosaurids were among the few marine reptiles to survive the Cretaceous–Paleogene extinction event. The dyrosaurids were a group of mostly marine, long jawed, crocodile-like quadrupeds up to 6 metres (20 ft) long. [1] The largest dyrosaurid was probably Phosphatosaurus estimated at 9 m (30 ft) in length.
Ursula Marvin argued that the asteroid impact explanation for the end-Cretaceous mass extinction was at odds with the idea of uniformitarianism and criticized those who attempt to reconcile the two as engaging in "newspeak". [95] Alvarez and Asaro measured the iridium levels of a 57m span of rock near the K–T boundary at Gubbio once more.
A longer version of the video posted to TikTok shows the reptile eventually walked into the ocean, where it quickly vanished beneath the waves. Florida is home to crocodiles and alligators, and it ...

Deinosuchus (/ ˌ d aɪ n ə ˈ sj uː k ə s /) is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period.
