[38] [39] Modern crocodilians can live as scavengers and survive for months without food, and their young are small, grow slowly, and feed largely on invertebrates and dead organisms for their first few years. These characteristics have been linked to crocodilian survival at the end of the Cretaceous.
During the Triassic, amphibians were mainly represented by large, crocodile-like members of the order Temnospondyli. Although the earliest lissamphibians (modern amphibians like frogs and salamanders ) did appear during the Triassic, they would become more common in the Jurassic while the temnospondyls diminished in diversity past the Triassic ...
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 Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.

Once grabbed and dragged into water, it is unlikely the victim will escape. Analysis of attacks show most-such attacks take place when crocodiles are guarding nests or newly hatched young. [152] Saltwater crocodiles have been implicated in over 1,300 attacks on humans between 2010 and 2020, almost half of which fatal. [151]
With the sun's radiation being severely diminished, the first species to die would be plants and animals who survive through the process of photosynthesis. This lack of food would ultimately lead to other mass extinctions of other animals that are higher up on the food chain and possibly kill up to 25% of the human population. [ 6 ]
Only 1,500 to 2,000 adult crocodiles survive in southern Florida’s brackish swamps, so seeing one on a public beach is highly unusual, according to the South Florida Wildlands Association.
