.4" Serrated, Theropod (Juvenile Allosaurus?) Tooth - Colorado
This is a small, serrated, .4" long theropod tooth collected this past summer. It comes from the Morrison Formation at our partners private quarry East of Dinosaur, Colorado. It's likely a juvenile Allosaurus tooth. There is a repaired crack in the middle of the tooth.
Allosaurus was a theropod of the Late Jurassic that lived from 156 to 145 million years ago. It was a predator with a massive skull, serrated teeth, and gaping jaws. This powerful and plentiful carnivore genus could grow more than 30 feet long. Due to how plentiful it's fossils are in the Morrison Formation, it's been suggested that they may have been a pack hunter.
