When Did Crocodilians First Appear?

The first crocodilians appear about 250 million years ago.

When Did Crocodilians Go Extinct?

Crocodilians have not gone extinct. In fact, modern crocodilians have changed very little in 50 million years! Some species such as Sarcosuchus and Deinosuchus have died out, but as a whole the order has done very well throughout its time. It even survived the K-T extinction that killed off the dinosaurs!

What Did Early Crocodilians Look Like?

Early crocodilians looked very much like modern crocodiles and alligators. The species that are extinct now looked much like modern species as well. The biggest difference was size: Sarcosuchus (110 million years ago) was the largest know crocodilian, reaching about 40 feet (11-12 meters) long. Most crocodilians were about the same size as modern species. All crocodilians have the same characteristic tubular bodies, splayed stances, long flat snouts, and conical teeth. Alligators and caimans have shorter, broader snouts, while gharial and false gharial species have longer, thinner snouts. Crocodiles have longer and more pointed snouts than alligators and shorter, wider snouts than gharials and false gharials.

Are Crocodilia And Phytosaurs Related?

Crocodilia and phytosaurs are not related. They are an example of convergent evolution, where two groups evolve similar characteristics in response to environmental conditions but share no common ancestor.
