Triceratops Bone - Authentic Hell Creek Fossil Specimen

Triceratops belongs to the Ceratopsidae - the horned dinosaurs of the Late Cretaceous. In adulthood, Triceratops measured 29 feet (9 m) long and 10 feet (3 m) tall, with its distinctive three-horned head comprising nearly one-third of its total body length. Studies of bone lesions in the cranium and frill confirm that Triceratops used its horns in combat - and as one of the last non-avian dinosaurs to appear before the K-Pg extinction, it roamed the same landscapes as T. rex in the final chapter of the Mesozoic. This authentic Triceratops bone fossil is recovered from private land in the Hell Creek Formation of South Dakota. From the Last Landscape of the Dinosaurs This is not a cast. This is a genuine fossilized Triceratops bone fragment from the Hell Creek Formation - one of the most significant Late Cretaceous fossil sites in the world. Specimens measure approximately 0.75 in to 1.5 in (2 cm to 3 cm) in length. Each piece varies in size and shape and is completely unique. The specimen is housed in a glass-topped riker display case measuring 4 in x 3 in x 1 in. The Authentic Triceratops Bone Fossil for Collectors Research on Triceratops combat behavior suggests that about one-third of the adult horn was hollow at the base, making the horns effective display structures as well as combat weapons. Progressive changes in horn orientation during adolescence indicate visual signals of maturity onset. This fossil fragment connects the holder to one of the most behaviorally complex and visually dramatic dinosaurs ever documented. Each specimen includes a Mini Museum certificate of authenticity and informational display card. Explore more in our Prehistoric Collection and our Natural History Collection.
