Three teeth of the shark Serratolamna serrata (Agassiz) from the Guinea Corn Formation (Central Inlier) represent the first recorded occurrence of fossil sharks within the Cretaceous of Jamaica. This occurrence increases the known palaeogeographical distribution of S. serrata, which appears to have been global. This species is largely known from the Upper Maastrichtian, which helps confirm the stratigraphical position of the Guinea Corn Formation
