3.9" Ankylosaur Side Armor Spike With Stand - Texas

This is a very rare find from the Aguja Formation in West Texas. It's a 3.9" long, side armor spike of a currently undescribed Ankylosaur. Ankylosaur fossils are extremely rare, but this is even more so because so little dinosaur material has been collected from the Cretaceous of Texas. The formation it comes from would be the equivalent of the Judith River Formation in the Northern US and Alberta.

A partially articulated find from the same property this fall (currently being studied) hints that the Ankylosaurs at this locality are not just a new species but may represent a new genus entirely.

There is a crack repair with gap fill near the base of the spike and some surface restoration on one side near the tip. It comes with a custom metal stand.

This specimen was collected last 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.
