The bizarre fauna of prehistoric Florida is nothing short of fascinating. Amongst every type of mammal that ever walked this part of the planet millions of years ago, some of the most interesting and dangerous beasts can be found in the fossil deposits of Florida in the United States. This is an ULTRA RARE (first time we have seen ANY fossils of this species!) mandible with original carnassial molar from the prehistoric Bone-Crushing dog called Osbornodon scitulus. Fossils of this extinct apex predator species of bone-crushing dog are RARE and unheard of in private collections as well as being scarce amongst institutional repositories. Collections that include atypical and rare fossils such as this one set the collection apart from your typical hobbyist collections made up of common, commercial varieties of fossils.
This carnivore fossil is an extreme rarity and comes from one of North America's most dangerous prehistoric predators. This mandible is nearly complete with an intact original primary lower carnassial tooth and a partial presence of a premolar. There has been nothing done to this scientific treasure and it is as found. PREHISTORIC BONE-CRUSHING DOG FOSSILS ARE SUPER RARE AND ONLY FOUND AT A HANDFUL OF SITES IN THE U.S..
Species of Osbornodon were members of the early canid family of Hesperocyoninae, a type of large bone-crushing dog. These were robust canids that lived in prehistoric North America that had unusually well-developed bone-cracking jaws for devouring large prey. The anatomy of these animals can be described as having robust, broad and powerful bodies with high-domed skulls, short muzzles and strong jaws lined with bone-crushing teeth. They were about the size of a coyote but much more powerful and thick in body structure. Prehistoric canids like the Dire Wolf replaced these creatures when they died out of the end of the Late Pliocene.
