Long before the word "raptor" entered popular culture, Dromaeosauridae were already among the most sophisticated predators of the Mesozoic. Fast-moving, carnivorous, and possibly feathered, these Cretaceous hunters are now understood to be among the closest dinosaurian relatives of modern birds. This authentic raptor bone fossil is a piece of a real Dromaeosaurid specimen recovered from the Hell Creek Formation - one of the most important dinosaur fossil sites in the world. A Real Piece of the Cretaceous With their delicate skeletal structure and possible flight-related adaptations, Dromaeosaurid bones are among the more fragile and rare components of the Hell Creek fossil record. This specimen measures approximately 1 cm and is presented in a glass-topped riker display case with an informational card that also serves as the certificate of authenticity.
