This is an authentic fragment from a rib of Triceratops, one of the most iconic ceratopsian dinosaurs.

Triceratops was a massive herbivore famous for its three facial horns, powerful parrot-like beak, and enormous bony frill. These giants roamed what is now North America during the final days of the Late Cretaceous (~68-66 million years ago), right up to the mass extinction event. 

Sourced from the renowned Hell Creek Formation in Montana, this fossil comes from ancient floodplain and river environments that once teemed with iconic dinosaurs like Triceratops, Edmontosaurus, and Tyrannosaurus rex.

Specimen Highlights:
