lamniform shark, Squalicorax probably would have
resembled a modern
Great White shark. Aside from swimming the northern oceans between
North America, Europe and North Africa, an articulated skeleton of
Squalicorax, S. falcatus, has
been recovered from the US state of
Kansas. This indicates that Squalicorax was also
swimming in the
Western Interior Seaway that once submerged the mid US, along with much
of Canada. These would have been dangerous waters for even a fully
grown Squalicorax, as giant mosasaurs such as Tylosaurus
swimming these waters at the time.
Squalicorax is a confirmed dinosaur eater, with evidence of this coming from a metatarsel (foot bone) of a hadrosaurid that has a Squalicorax tooth embedded in it. The general consensus is that the dinosaur had been swept out to sea and had its body scavenged by a wandering Squalicorax that may have picked up on its scent in the water.
