摘要：

A partial vertebral series of a lamniform shark (Chondrichthyes: Elasmobranchii) occurred in the "Vallecillo fish Member" of the Agua Nueva Formation (Upper Cretaceous: Lower Turonian) at Vallecillo, Mexico. Its taxonomic assignment below the ordinal level is tenuous, but the vertebrae closely resemble those of cretoxyrhinid sharks. This report represents the first documentation of a Cretaceous lamniform shark in northeastern Mexico. The shark could have measured slightly over 3 m in total body length. Because the vertebrae are articulated and are three-dimensionally preserved, they are thought to be deposited rather quickly on a soft oceanfloor after decomposition of most of the shark carcass.
