1.1" Fossil Dinosaur Jaw Fragment - Aguja Formation, Texas
This is a 1.1" fossil of jaw fragment from the Aguja Formation, Brewster County Texas. The tooth socket crenulations suggest it may be from a hadrosaur but there are not enough diagnostic features to assign to a family with any degree of certainty.
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 within the boundaries 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.
