Limestone Hill (Permian of the United States)

Where: Maryland (39.1° N, 81.4° W: paleocoordinates 4.0° S, 15.9° W)

• coordinate estimated from map

When: Greene Formation (Dunkard Group), Sakmarian (293.5 - 290.1 Ma)

• "In the early 1930s, R. W. Whipple of Marietta College (Ohio) collected two series of lepospondylous vertebrae from the Ninevah Limestone (Greene Formation, Dunkard Group, Permian) at Limestone Hill, WV."

Environment/lithology: terrestrial; limestone

Size class: macrofossils

• "One specimen consists of an articulated series of approximately 17 dorsal and six caudal vertebrae. The dorsal centra are large for a lepospondyl (1.6 cm long). The caudal centra, seemingly from tail's end, are smaller, approximately 0.5 cm long. The second specimen consists of two articulated, but fragmentary, caudal vertebrae whose centra are about 1.5 cm long."
