.78" Allosaurus Tooth On Original Matrix

This is a tooth of Allosaurus fragilis, an apex predator of the Jurassic. It's .75" long and still embedded in the original matrix it was found in.

It was prepared that it sticks straight up from this free-standing piece of matrix. The tooth has nice enamel preservation and good serrations.

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.
