In the Upper Cretaceous, a second order of batoids appears in the fossil record, the Myliobatiformes. The teeth are small and arranged in numerous files.
Females have a crushing, and males often a clutching, dentition.
Many of the challenges encountered with skate teeth are relived with the dasyatids. The number of extant species is fewer, but there seems to be significantly less research material available. From personal experience, I have collected over a thousand dasyatoid teeth from the mine and the DPW site. As was done with the skates, it would be useful to look at the extant species of the western Atlantic for potential stingray species that might be represented at Lee Creek, particularly in the Yorktown. As previously discussed, the Pungo River Formation is thought to have been a subtropical environment and the Yorktown, warm temperate.
