This is a 1.55" long Allosaurus tooth still embedded in the sandstone that it was found in. The tooth has nice enamel and unlike most Morrison teeth is NOT heavily fractured. It was collected this past year from our partners private quarry near Dinosaur, Colorado.
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.
