First added to the fauna list of New Jersey in 2004¹, the teeth of Pseudocorax affinis are rare and bear a resemblance to the more commonly found teeth of Squalicorax kaupi. While both species belong to the same family (Anacoracidae) there are marked differences between the two species. The root of Pseudocorax affinis is moderately robust and strongly bilobate with a distinct nutrient groove. This nutrient grove is completely lacking in all of the Squalicorax species. The crown is moderately broad and lacks the long convex mesial cutting edge that is so distinctive of Squalicorax, there is a distinct notch on the distal side.

Labial view of P. affinis, the root has a "U" shape.
