1.54" Allosaurus Tooth - Skull Creek, Colorado

This is a 1.54" long tooth of Allosaurus fragilis from the Skull Creek Quarry near Dinosaur, CO It has good enamel preservation though most of the serrations are worn. It's good sized as Allosaurus teeth tend to average about 1" long. There are a few crack repairs and small gap fills in the tooth but this is pretty typical of teeth from the Morrison Formation which are almost always found in pieces.

This tooth comes from what is being called the "Salt & Pepper Layer" in the quarry. A meter and a half thick sandy layer which probably represents a river channel deposit. It mostly contains isolated teeth and tumbled bone fragments. The quarry is also the location of the recently announce "Elvis" Torvosaurus find.
