Champsosaurus Gigas was a formidable Cretaceous predator that defied expectations. Though it resembled a crocodile, this diapsid reptile belonged to an entirely separate lineage, making it a fascinating evolutionary parallel. Its gharial-like snout, elongated and precise, was perfectly adapted for capturing swift fish and smaller prey. Yet the expanded rear skull housed powerful jaw muscles capable of delivering a surprisingly forceful bite—or executing lightning-fast strikes on elusive quarry. Among Champsosaurus species, C. Gigas stood out as a giant, reaching lengths exceeding three meters. This authentic vertebra from the Hell Creek Formation offers a tangible connection to a remarkable creature that thrived millions of years ago, complete with a certificate of authenticity.
