About Mapusaurus
Mapusaurus (lit. 'earth lizard') is a genus of giant carcharodontosaurid dinosaur that lived in Argentina during the Albian age of the Early Cretaceous. It is known from a bonebed of between seven and nine specimens, excavated from the strata of the Huincul Formation between 1997 and 2001 as part of the Argentinian-Canadian Dinosaur Project. In 2006, Rodolfo Coria and Philip J. Currie scientifically described Mapusaurus. Only one species of Mapusaurus, M. roseae, has been described, named after the rose-colored rocks in which it was discovered and sponsor Rose Letwin. Another carcharodontosaurid, Taurovenator, was once believed to be a synonym of Mapusaurus. However, the description of a more complete specimen of Taurovenator demonstrated that they are separate taxa.
