Species with the prehistoric origin are usually extinct. However, some of those very old species managed to survive.
Sharks, crocodiles, and horseshoe crabs appeared on this planet around the same time as dinosaurs and they still exist.
A recent discovery of a prehistoric species is quite scary. The rarely seen frilled shark was captured on video. This creature seems to be 80 million years old, which means that frilled shark is even older than dinosaurs.
Based on this footage, it has been concluded that this prehistoric shark has not changed much over time.
