More About Kronosaurus

Kronosaurus was a huge marine reptile; it was a plesiosaur, not a dinosaur. It lived in the open oceans and breathed air. Kronosaurus swam using its four paddle-like flippers and probably crawled up onto the beach sand to lay eggs (like modern-day sea turtles).

Anatomy: This short-necked plesiosaur was a marine reptile 30 feet (9 m) long. It had four flippers, a huge head with strong jaws, and a short, pointed tail. The head was up to 9 feet (2.7 m) long, about 1/4 of the entire length of the body.

Diet: Kronosaurus ate ammonites and other cephalopods. Fossilized plesiosaurs and turtles have been found in the stomach cavity of Kronosaurus. Kronosaurus had strong jaws and sharp teeth. It had rounded teeth at the back of the jaws, used to crush shells. Kronosaurus was one of the top predators in the seas of the Mesozoic Era.

When Kronosaurus Lived: Kronosaurus lived in the sea during the early Cretaceous period, when there were many dinosaurs on Earth.

Fossils: Kronosaurus fossils have been found in Australia and Colombia, South America. It lived during the early Cretaceous period.
