4.2" Theropod (Tyrannosaur) Caudal Vertebra - Texas

This is a 4.2" long Tyrannosaur caudal vertebra collected this past spring from the Aguja Formation in Texas. It's most likely from one of the currently undescribed Tyrannosaurs from the formation. This vertebra is a surface find, hence the heavy erosion of bone. There are multiple repaired cracks and sections of bone, however there is no indication of any restoration.

This specimen was collected within the past year on private deeded property in Brewster County, Texas. You won't see any other dinosaur material from the Aguja & Javelina Formations for sale because nearly all of the formation lies the borders of a national park or in Mexico which can not be collected. One of our partners was lucky enough to purchase several hundred acres of ranch land in Texas containing a good exposure of these formations and we will be offering more material from the locality in the future.
