Age - Cretaceous Commonality - Very uncommon?
One of two species of nurse shark found in NJ, Cantioscyllium decipiens was added to the fauna list of New Jersey in 2008 ¹ The teeth of C decipiens are small, averaging between 4 and 5 mm (3/16's of an inch) across and similar to the teeth of the other nurse sharks. Distinguishing characteristics of C decipiens are the presence of one to three weak cupslets on each shoulder and strong wrinkles on the labial side of the tooth. The root has a single large medial nutrient pore and a single pair of lateral pores.
