1.8" Hadrosaur Caudal Vertebrae - Javelina Formation, Texas

This is a 1.8" long, caudal (tail) vertebrae of a Hadrosaur from the Javelina Formation of Texas . Little scientific work has been done on the dinosaurs from this formation so we can't put a definitive ID on it, but it's possible Gryposaurus. The formation is the equivalent of the Hell Creek and Lance Creek Formations several states to the north.

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.
