This is a RARE fossil partial jaw and original molar tooth from a MULTITUBERCULATE mammal from the Cretaceous Period called Meniscoessus. The jaw and associated tooth is extremely well-preserved with it unusual crown. Fossils from these tiny Mesozoic mammals are rare, especially teeth still embedded in skull fragments. Incredibly long hours collecting and microscope examination are required to locate fine specimens like this. While very tiny indeed, this fossil is exceedingly rare and specimens such as this are seldom found in private collections or even museums!
When most people think of the Mesozoic Period, they envision the Earth crawling with all types of reptiles and dinosaurs. The underdogs of this time were the small mammals that emerged and scampered about beneath the feet of some of the planet's largest dinosaurs that ever lived. They also likely scavenged on the carcasses of Tyrannosaurus rex's prey and were most probably prey themselves to many of the smaller dinosaurs including the famous dromaeosaurs ("raptors"). Mesozoic mammal fossils are important remnants in exhibits and collections to fully paint a picture of the varying fauna of the Earth during the days of the dinosaurs. Most fossil collections lack Mesozoic mammal fossils because of their extreme rarity because they are small making them difficult to locate. Another reason for their rarity is the fact that they are fragile, making them rare to survive the fossil process. The specimen we offer here is a highly recommended addition for a well-diversified and educationally valuable collection.
