3.6" Fossil Theropod (Tyrannosaur) Vertebra - Aguja Formation, Texas

This is a 3.6" long fossil theropod vertebra centrum collected from the Aguja Formation in Texas. It is in good condition with wear along the edges and missing vertebral arch and processes. It's likely this is a caudal (tail) vertebra.

Comes with the pictured custom metal display stand.

There are a number of undescribed Tyrannosaurs from the Aguja Formation and this bone is likely from one of them.

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.

These formations are equivalent age to the Judith River Formations in the Northern US/Alberta. Because relatively little collecting has been done on these formations in Texas most of the species remain undescribed. Our partner has been putting important material into research collections and working with museums and researchers, so in the coming years their work will help lead to these dinosaurs being formally described.
