Gateway to the Paleobiology Database
North of Dockum (Miocene to of the United States)

Where: Dickens County, Texas (33.5° N, 100.8° W: paleocoordinates 33.9° N, 98.4° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Miocene to Miocene (23.0 - 0.0 Ma)

• age unclear: assumed by Cope (1892) to be "Pliocene," but the local geology is unknown and the "Blanco Beds" are not present, so the unit could be anything from the Ogallala to Pleistocene alluvium

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Collected by W. F. Cummins in 1891

• ANSP collection
