In the National Museum collection there is a single example of a scute pertaining to some lepidotid fish (No. 1063, Kiowa shales). Cope has described Macrepistius of this family from a stratum between the Upper and Lower Trinity Sands of Texas. It seems very probable that the teeth referred to the vomer of Mesodon abrasus really belong here.
