Adocus sp.

Specimen —USNM 357834, a third right peripheral element, discussed in Weems (1988) and Hutchison and Weems (1998).

Locality, horizon, and age — Found at the Hampton Mall in Prince Georges County, Maryland, probably in the Brightseat Formation, early Paleocene (Danian) .

Remarks —A peripheral of a non-marine turtle from the early Paleocene Brightseat Formation was considered by Weems (1988) to belong to Agomphus sp. because it showed no obvious surface sculpture. However, this specimen was reassigned to Adocus sp. by Hutchison and Weems (1998) because it does have a faint pitted surface texture that was largely obliterated before the specimen was buried. Therefore, it is Adocus that occurs in the Brightseat Formation and not Agomphus , though the presence of Agomphus tardus in the laterally equivalent Hornerstown Formation in New Jersey to the northeast implies that this taxon may yet be found in the Brightseat.
