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. [1]

Discovery and naming
changeThe 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.[1] 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.[2]
