HUGE, 2.58" Allosaurus Tooth - Colorado

This is a HUGE Allosaurus tooth from the "Salt & Pepper Quarry" near Dinosaur, CO. Most Allosaurus teeth are between 1 and 1 1/2 inches but this one is a whopper at 2.58" long. In fact it's the largest Allosaurus tooth found at the quarry since they started excavations 3 years ago. Prior to preparation they assumed it was a Torvosaurus tooth because of it's size.

The tooth is in good shape with most of it's serrations still present. It has good enamel and very minimal repair and restoration.

This tooth comes from what is being called the "Salt & Pepper Quarry", near Dinosaur. Colorado. Within the past several years this quarry has produced articulated remains of several types of dinosaurs including large theropods, sauropods and Ornithischia. There is a thin layer in the quarry, probably representing a sandy river bottom that produces many isolated teeth and tumbled bone fragments. This tooth was collected this summer from layer. There are far few commercial quarries operating in the Morrison Formation that the Cretaceous aged Hell Creek Formation so material is much more rare and sought after by collectors.
