# Allosaurus Vertebra Fragment - Authentic Morrison Formation Fossil Specimen - Medium

With its iconic skull "hornlets" and powerful bipedal build, **Allosaurus** was the dominant large predator of the Late Jurassic - an apex carnivore that lived over 145 million years ago and hunted the same Morrison Formation landscapes as Brachiosaurus, Apatosaurus, and Stegosaurus. This **authentic Allosaurus vertebra fossil** in the medium size is a larger fragment of real Allosaurus backbone recovered from private land in the Morrison Formation of Utah, presented in a glass-topped riker display case.

## **More of the Jurassic Apex Predator's Backbone**

The medium-sized Allosaurus vertebra fragment offers more surface area to examine the deep pleurocoels and distinctive morphology of theropod vertebral anatomy. Allosaurus used its powerful build and possibly cooperative pack hunting tactics to take down prey far larger than itself - including the giant sauropods that shared its ecosystem. This is not a cast. This is a genuine Jurassic fossil, approximately 145 million years old.
