Why did crocodiles not evolved?

Our crocodiles evolved from an animal in the prehistoric period called a Phytosaur. But their big sizes didn’t evolve until the Cretaceous period about 100 million years ago. Many scientists believe that one of the reasons crocodiles haven’t had to evolve much is because of their predator strategy (how they get food).

Why did crocodiles survive but 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.

How long have crocodiles been around for?

About 80 million years ago, during the Cretaceous period, crocodilians appeared.

Will crocodiles go extinct?

It certainly has in modern times. We haven’t lost a species of crocodile to extinction since humans have been dominant on the planet, even in the last few hundred years when our impact has been appalling. The reason appears to be in large part because crocodiles learn quickly and adapt to changes in their situation.

How long have crocodiles been around on Earth?

As a group the Crocodyloformes have been around for 225 million years, but true crocodiles have been around for 55 million years and alligators have been around for 37 million years.

Why are crocodiles more impressive than the dinosaurs?

One way in which prehistoric crocodiles were indeed more impressive than their terrestrial relatives was their ability, as a group, to survive the K-T extinction event that wiped the dinosaurs off the face of the earth 65 million years ago.

Why are crocodiles not extinct in the wild?

It is amazing to experts that they didn’t end up extinct about 65 million years ago when the dinosaurs did. They also haven’t been affected by evolution and look very much today like they did all those years ago. Crocodiles have one of the most complex structures and anatomy of any animals out there.

Which is species has been around longer crocodile or alligator?

Answer Wiki. 1 Answer. , minor encyclopedia poorly disguised as a human computer programmer. Neither “crocodile” nor “alligator” refers to a species; both are larger groups, so the question doesn’t really make sense — presumably some crocodile species have been around longer than others, for instance.

Why are crocodiles becoming extinct?

Many crocodiles are at the verge of extinction whereas some of them are classified as critically endangered. While most crocodilian species faced almost-extinction situation because of the habitat degradation or deforestation, others were illegally hunted, still others died of road collision.

Did crocodiles descend from dinosaurs?

Well, the fact is that dinosaurs, pterosaurs and crocodiles are all descended from archosaurs, the “ruling lizards” of the late Permian and early Triassic periods.

What survived the KT extinction?

About 50 percent of the planet’s animal and plant life survived the Cretaceous -Tertiary mass extinction, also known as the K/T boundary. Here are some of the animals whose ancestors walked (or swam) alongside dinosaurs: Platypuses . The platypus is one of the few monotremes still in existence today.

Is a crocodile a dinosaur?

Crocodiles are not dinosaurs, but they are closely related, and they share a common ancestor. Crocodiles have their own fascinating fossil history, and we’ll never truly know just how diverse in size and lifestyle the prehistoric crocodiles truly were.

around 200 million years old
Relatives of crocodiles have been around for an extraordinary length of time, their fossil remains having been found in rocks from the early Jurassic period, around 200 million years old.
