Scientific name: Dromaeosaur indet - family Dromaeosauridae - Theropod raptor Dinosaur PREMAXILLARY Tooth Location: Private Ranch in Montana, USA Geological Formation: Judith River Formation Age: Late Cretaceous, Campanian stage, (~79-75 Million Years) Size: 6,9mm REF.: #S104 DESCRIPTION: Dromaeosaur teeth from the Judith River Formation are from the Late Cretaceous period and belong to feathered, raptor-like dinosaurs such as Dromaeosaurus and Saurornitholestes. These teeth are typically small, sharp, and serrated, ideal for a diet of small animals like lizards, mammals, and baby dinosaurs. Key identification features include a distinctive twist in the anterior carina and serrations that can be finer on the front edge than the back. Characteristics of dromaeosaur teeth from the Judith River Formation: Classification: The teeth come from small, fast theropod dinosaurs known as dromaeosaurs, or "raptors". Period: They are from the Campanian stage of the Late Cretaceous, approximately 79-75 million years ago. Diet: These dinosaurs were predators that fed on small animals, and their teeth were equipped for this purpose. Distinctive features: Serrated edges: The teeth have serrations along the edges, which are like tiny teeth themselves. Twisted carina: A key feature is a twist in the anterior carina (the ridge running along the front edge of the tooth). Serration density: Serrations can be finer on the front edge (approx. 22 per 5mm) than on the back edge (approx. 17 per 5mm). Multiple species: The formation contains teeth from different dromaeosaur species, including the more robust Dromaeosaurus and the more slender Saurornitholestes. Observations about this specimen: Its morphology corresponds with a premaxillary tooth. A true rarity. Tiny jewel perfect for the most discerning fine professional collectors.
