9.2" Hadrosaur (Duckbilled Dinosaur) Chevron - Texas
This is a 9.2" chevron of a large Hadrosaur (duckbilled dinosaur) from the Aguja Formation in Texas. It has several repaired cracks but has not been restored.
A chevron is one of a series of bones on the ventral (under) side of the tail in many reptiles, including dinosaurs. Their main function is to protect critical elements in the tail such as nerves and blood vessels from being damaged when the animal either supports its weight on its tail, or pushes it against a hard surface to propel itself.

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 Big Bend National Park or in Mexico, where laws prevent collection of fossils for sale. One of our partners was lucky enough to purchase several hundred acres of ranch land in Texas containing a good exposure of these formations.
These formations are equivalent age to the Judith River Formations in the Northern US and Alberta, Canada. Because relatively little collecting has been done on these formations in Texas, most of the species remain undescribed. Our partner has been putting important material into research collections and working with museums and researchers, so in the coming years their work will help lead to formal descriptions for these dinosaurs.
