.72" Fossil Crocodile and Hadrosaur Tooth - Aguja Formation

This is a .72" fossil crocodile (Goniopholis sp.) tooth and a .16" hadrosaur (Hadrosauridae sp.) tooth from the Late Cretaceous, Aguja Formation of Texas. They are in good condition and still attached to the rock in which they were found. The hadrosaur tooth is on the side containing lettering and on the opposing edge.

Goniopholis is an extinct genus of crocodile known primarily from Europe and Africa. It has recently been identified in late Jurassic and early Cretaceous deposits in North America.

Hadrosaurs are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that roamed Asia, Europe, and North America during the Upper Cretaceous Period. Many species of Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.

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 and Javelina Formations for sale because nearly all of the formations lie within the boundaries of Big Bend National Park, where fossils may not be collected, or in Mexico, where fossils cannot be commercially traded. 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.
