This Acheroraptor "raptor" dromaeosaur dinosaur fossil tooth is a superb specimen. It possesses finely detailed and intact serrations. The enamel is a beautiful dark rich brown hue with naturally lustrous enamel preservation.
Acheroraptor is an extinct genus of dromaeosaurid theropod dinosaur known from the latest Maastrichtian Hell Creek Formation of Montana, United States. It contains a single species, Acheroraptor temertyorum. A. temertyorum is one of the two geologically youngest known species of dromaeosaurids, the other being Dakotaraptor, which is also known from Hell Creek.
At the time of writing Acheroraptor is only known from a maxilla and dentary with additional referred teeth. These however have been enough to at least confirm that Acheroraptor was actually a North American cousin of the famous Velociraptor that lived in Asia. Comparison of the known Acheroraptor fossils at least suggest that the total length of the holotype individual of Acheroraptor would have been somewhere in the region of about two meters in length.
The famous Hell Creek deposit in the Northwestern United States has been immortalized again and again on numerous TV documentaries. For its astonishing array of dangerous and large prehistoric predator fossils, no place has captured more attention or has been featured more in the news than Hell Creek! Fine grade fossils from this formation are amongst the most sought after specimens for collectors around the world. Most of the dinosaurs we grew up learning about as kids, come from Hell Creek!
Despite how dromaeosaurs are portrayed in the movies, most were only knee-high and about the size of small dogs, hence the very small teeth that are usually found. Dromaeosaur teeth are found in micro-sites carefully scanning the tiny fossils found in prehistoric environments that once were rich habitats such as swamps, springs or stream beds.
