Squalicorax ("Hairabe") is an extinct genus of the mackerel shark species that lived during the Cretaceous Period .

Like the majority of extinct shark species, Squalicorax is best known in the form of fossil teeth . In the US state of Kansas , however, a 1.9 meter long skeleton of the species S. falcatus was found that was anatomically preserved . The total length of S. pristodontus was estimated to be up to five meters based on the size of the teeth .

Squalicorax's teeth had a rectangular base, the crown was in the shape of a rose thorn and was finely serrated. They resembled those of the recent tiger shark . Squalicorax was probably a predatory fish , but fossilized teeth in the metatarsal bone of a young hadrosaur and in the vertebra of a mosasaur suggest that Squalicorax ate opportunistically and also ate carrion .
