Cristatusaurus

Cristatusaurus was a carnivorous theropod dinosaur from the Early Cretaceous of West Africa. Its fossils look very similar to the ones from "Baryonyx" and "Suchomimus." 
Discovery and naming.
The first specimens were found in Niger in 1973 by a French paleontologist named Philippe Taquet. The name of the animal refers to the Latin word for crest, ""crista"," because it had a crest on its snout. The species "lapparenti" is named after another French paleontologist called Albert-Félix de Lapparent. The fossils discovered so far include two broken snout bones, some pieces from the upper and lower jaws, a claw, and four backbones (also called "vertebrae"). Scientists aren't sure if "Cristatusaurus" is a new species, some of them say it could be the same dinosaur as "Suchomimus" or "Baryonyx."
