4.8" Fossil Hadrosaur Phalanx - Aguja Formation, Texas

This is a beautifully preserved, 4.8" wide phalanx (toe bone) of a hadrosaur (duck-billed dinosaur) from the Aguja Formation of Texas. It's suspected that there are several species of Hadrosaurs in the formation so we can't positively ID an individual bone like this down to a genus or species level.

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.
