Where: Saint Marys County, Maryland (38.4° N, 76.6° W: paleocoordinates 38.6° N, 74.6° W)

• coordinate estimated from map

When: St Marys Formation (Chesapeake Group), Tortonian (11.6 - 7.2 Ma)

• USNM 9352 lacks detailed stratigraphic information, although Cope believed that it may have been derived from the “Yorktown Formation” [90: 145] – later corrected to St Mary Formation by Kellogg [93]. Strontium dating indicates the Little Cove Point Member of the St Mary‟s Formation to be almost exclusively early Tortonian (11.7–10.0 Ma) [48, 49]. Note that de Verteuil and Norris [94] estimated the relevant portion of the St Mary‟s Formation to be younger (ca. 10.4–8.8 Ma). However, their assignment of these strata to dinoflagellate zone DN8 for the most part does not preclude the older strontium dates [94: fig. 3]. (Marx & Fordyce, 2015)
