This is a RARE set of TWO DIFFERENT GROUPS of dinosaur-era Mesozoic mammals from the Cretaceous Period - MULTITUBERCULATES and METATHERIANS. These fossil teeth were found in the famous Hell Creek Formation. The long tusk-like incisor tooth with partial root is from a Cimolodon, a small mammal from the Multituberculate mammals. The smaller pre-molar tooth is perfect with COMPLETE root and is from an Alphadon, a member of the Metatherian mammals.
The set of having both types of these Mesozoic mammals make for a great reference and educational study/display fossil set. Both teeth are extremely well-preserved with their own respective unique anatomy. Complete isolated teeth from these tiny Mesozoic mammals are rare, especially these prominent incisors. Fossils like these require incredible collecting and microscope examination time to locate. These fossils are EXCEPTIONALLY rare and are RARELY found in private collections!
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.
