Squalicorax

Squalicorax is a genus of extinct shark-like fish that lived during the Cretaceous period. It belongs to the family Squalodontidae, commonly referred to as squalodonts. These animals were among the top predators of their ecosystem and are known for their distinctive appearance.

Fossil evidence suggests that Squalicorax lived about 65 to 95 million years ago, during the Cenomanian to Santonian ages of the Late Cretaceous. The genus was once thought to be a member of the family Squalidae, but it has since been reclassified into Squalodontidae based on morphological and phylogenetic analysis. Squalicorax fossils have been found in North America, Europe, Asia, and Africa.

Physical characteristics of Squalicorax fossils reveal a shark-like body with a short, broad snout and small teeth. Adults typically reached lengths of 6 to 10 meters (20 to 33 feet). They likely preyed upon fish, squid, and other marine mammals, as well as armored reptiles like Corbulicrinus and Placodus.

Several species of Squalicorax have been identified, including S. giganeus, S. falcatus, and S. kaupi. The genus is notable for its exceptional preservation in the fossil record, particularly in the Maastrichtian stage deposits in North America. Despite its impressive reputation as a top predator, the taxonomic status of Squalicorax is subject to change as new evidence and studies become available. Research continues to refine our understanding of these fascinating ancient marine animals.
