1.45" Serrated, Allosaurus Tooth On Sandstone - Colorado
This is a robust, 1.45" long, serrated Allosaurus tooth collected this summer from our partners private quarry East of Dinosaur, Colorado. A fair amount of enamel is worn away but it has really nice serrations and is very thick in cross section. There is one repaired crack in the middle of the tooth. The sandstone it was found in was shaped to create a nice display base for 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.
