Why did crocodiles survive and not dinosaurs?

Crocodiles survived the asteroid strike that wiped out the dinosaurs thanks to their ‘versatile’ and ‘efficient’ body shape, that allowed them to cope with the enormous environmental changes triggered by the impact, according to new research. Crocodiles can thrive in or out of water and live in complete darkness.

Did archosaurs survive the PG extinction?

Extinct archosaurs include non-avian dinosaurs, pterosaurs, and extinct relatives of crocodilians. Birds and several crocodyliform lineages were the only archosaurs to survive the K-Pg extinction, rediversifying in the subsequent Cenozoic era.

How did alligators survive the asteroid?

They live near the water However, for some reason, freshwater rivers and lakes were less impacted by the meteor. This helped the Crocodiles survive, as their amphibious lifestyle let them roam the rivers to escape the land and sea disasters.

Did archosaurs evolve dinosaurs?

Dinosaurs evolved from other reptiles (socket-toothed archosaurs) during the Triassic period, over 230 million years ago. Dinosaurs evolved soon after the Permian extinction, which was the biggest mass extinction that ever occured on Earth.

Why did crocodiles get smaller?

In the case of crocs, climate change – the cooling temperatures during the Cenozoic – probably contributed to the comparatively large sizes of today’s species. Crocs became more restricted to the tropics and this possibly led to the extinction of smaller species.

What did archosaurs look like?

Most archosaurs had long hind legs and short forelimbs. All archosaurs had a large opening of uncertain function on the snout in front of the eye (antorbital fenestra) and another at the junction of three bones in the lower jaw (mandibular fenestra).

Why is a crocodile an Archosaur but not a dinosaur?

The primary characteristic that unifies archosaurs is two openings on the side of their skulls. These tetrapods, or four-legged vertebrates, splinter into two groups: bird crocodiles (Ornithosuchia) and false crocodiles (Pseudosuchia).

Are crocodiles evolved from dinosaurs?

As far as reptiles go, crocodiles are closely related to dinosaurs. But they’re incredibly complex biological organisms that survived the meteor impact that ended the Cretaceous period roughly 66 million years ago — and did in their dinosaur relatives.

What dinosaur is the crocodile related to?

Deinosuchus are crocodylians — the group that includes modern alligators, crocodiles and gharials — and despite the name “terrible crocodile,” the Deinosuchus lineage was more closely related to alligators, the researchers determined. They also found that the species D.
