CLUPEIFORMES GOODRICH, 1909

FAMILY INDETERMINATE

CLUPEIFORM ? INDETERMINATE

FIG. 6B

Material— one eroded, broken specimen, DMNH 2021-09-10.

Description and Remarks— Although small and somewhat eroded, this specimen is tentatively assigned to the Clupeiformes and is included because of the rarity of clupeids in the Cretaceous. The outline of the sagitta, the flat inner face, and the shape of the sulcus indicate a possible clupeid. Schwarzhans et al. (2018b) assigned 13 specimens to Clupeiform indeterminate from the Eutaw Formation (upper Santonian) of Alabama.
