Euclastes wielandi ( Hay 1908)

Synonymy – Lytoloma angusta ? (partem) Wieland 1904, Lytoloma wielandi Hay 1908 , Osteopygis borealis Hay 1908 (partem), Erquelinnesia molaria Hay 1908 , Osteopygis emarginatus (partem) Zangerl 1953, Osteopygis emarginatus (partem) Weems 1988, Osteopygoides priscus Karl, Tichy & Ruschak 1998 , Euclastes priscus Lynch & Parham 2003 (partem) Euclastes wielandi Parham 2005 (partem).

Specimen –USNM 412113, palate composed of premaxillaries, maxillaries, and vomer, described in Weems (1988).

Locality, horizon, and age – Found at Hampton Mall, Prince Georges County, Maryland; Brightseat Formation; early Paleocene (Danian) .

Remarks –A pair of fused premaxillaries and maxillaries from the Brightseat Formation in Prince Georges County, Maryland were assigned by Weems (1988) to Osteopygis emarginatus following the taxonomy current at that time. Since then, Parham (2005) has demonstrated that only carapace and plastral material assigned to O. emarginatus properly belongs to that taxon, which belongs in the “ Macrobaenidae .” Skull material that had been assigned to O. emarginatus does not belong to that species and instead belongs to a pancheloniid turtle, Euclastes wielandi . Therefore, the Brightseat skull fragment has been taxonomically reassigned to E. wielandi and the Pancheloniidae.
