Cristatusaurus was a meat-eating dinosaur that lived in what is now West Africa during the Early Cretaceous period. This was about 112 million years ago! It was a type of theropod, which means it walked on two legs. Scientists have found its fossils, and they look a lot like those of two other dinosaurs, Baryonyx and Suchomimus.

Discovering the Crested Lizard

Finding Cristatusaurus Fossils

The first pieces of Cristatusaurus were found in Niger in 1973. A French paleontologist (a scientist who studies fossils) named Philippe Taquet discovered them.

The name Cristatusaurus means "crested lizard." This name comes from the Latin word "crista," which means "crest." Scientists gave it this name because they think it had a crest, or a ridge, on its snout. The second part of its name, "lapparenti," honors another French paleontologist, Albert-Félix de Lapparent.

What Fossils Were Found?

So far, the fossils found include two broken pieces of its snout bone. Scientists also found parts of its upper and lower jaws. A large claw and four backbones (also called vertebrae) were also discovered.

Is It a New Dinosaur?

Scientists are still trying to figure out if Cristatusaurus is a completely new type of dinosaur. Some experts believe it might actually be the same dinosaur as Suchomimus or Baryonyx. This is because their fossils look very similar. More discoveries might help solve this mystery!
