Teeth of the oceanic whitetip shark, Carcharhinus longimanus are an infrequent find in the Yorktown and possibly Pungo River formations. The teeth are moderately sized which is to be expected as the shark seldom exceeds three meters in length. This is unlike C. leucus or C. obscurus both of which commonly exceed this length. The teeth, upper and lower, are very erect, remaining so, even in most of the posteriors. Roots are only slightly arched across the bottom.

Upper teeth have moderately coarse serrations about half way up the blade until there is an abrupt change to fine serrations. They are fairly robust and have a relatively thick cross section. Due to their erectness, they present a very triangular appearance, particularly when viewed labially.

Lower teeth have extremely fine serrations which change to fine but visible serrations near the tip. They are robust and have prominent enamel shoulders. Anteriors have very long blades. The blades become shorter but wider presenting a more triangular appearance as one progresses mesially.
