These specimens are genuine fragments of a Triceratops frill. The frill consists of elongated bones that form part of the skull. Its functions likely included both defense against predators like Tyrannosaurus rex and visual display for other Triceratops.

Paleontologists have discovered Triceratops frills and brow horns with partially healed Tyrannosaur bite marks, indicating that these dinosaurs successfully defended themselves against attacks.

Triceratops was an enormous creature, similar in size to an African elephant. It could grow up to 30 feet (9 meters) in length and weigh over 11,000 lbs. (5,000 kg), with some larger individuals reaching nearly 15,750 lbs. (7,150 kg).

This particular Triceratops specimen originates from the Hell Creek Formation, a Cretaceous-age fossil site that dates to approximately 65.5 million years ago, marking the end of the age of dinosaurs.
