3" Fossil Dromaeosaurid Theropod Chevron - South Dakota
This is a fossil chevron bone of a dromaeosaurid theropod dinosaur, collected from the Hell Creek Formation of South Dakota. The deposit is Late Cretaceous in age, or approximately 66 million years old.
Chevrons, or haemal arches, are bones attached to the underside of caudal (tail) vertebrae, forming the ventral surface of the tail. A chevron comprises a left and right part, which are typically fused to each other in a V-shaped fashion, enclosing a large opening that can be seen in front or back view. The openings of multiple consecutive chevrons form the haemal canal of the tail, which protects nerves and blood vessels.

The Hell Creek Formation
Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
