Atrociraptor uh-trɑːsee-RAPTUHR

Atrociraptor () is a genus of dromaeosaurid dinosaur that lived during the Late Cretaceous in what is now Alberta, Canada. The first specimen, a partial skull, was discovered in 1995 by the fossil collector Wayne Marshall in the Horseshoe Canyon Formation, about 5 km from the Royal Tyrrell Museum of Palaeontology where it was brought for preparation. In 2004, the specimen became the holotype of the new genus and species Atrociraptor marshalli; the generic name is Latin for “savage robber”, and the specific name refers to Marshall. The holotype consists of the (frontmost bones of the upper jaw), a (main bone of the upper jaw), the (tooth-bearing bones of the lower jaw), associated teeth, and other skull fragments. Isolated teeth from the same formation have since been assigned to Atrociraptor.
