A rare find in the Lee Creek mine, the Galapagos shark, Carcharhinus galapagensis occassionally turns up in the Yorktown and possibly Pungo River formations. The teeth are moderately sized and very similar to those of the dusky shark, C. obscurus , except proportionally longer relative to width. The upper teeth have a gentle mesial curve.
Serrations are moderately coarse near the base, gradually becomine finer towards the tip.
The base of the root is prominently arched. Lower teeth are very erect, finely serrated, and have long cusps. Enamel extends well down over the root shoulders. Root bases are gently arched. 1 - labial and Fig.
