Also known as Ryers Valley 401

Where: Northern Cape, South Africa (32.1° S, 22.1° E: paleocoordinates 59.6° S, 33.8° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Pristerognathus Assemblage other zone, Poortjie Member (Teekloof Formation), Capitanian (264.3 - 259.5 Ma)

• lower Teekloof Formation, in the uppermost Poortjie Member.iostratigraphically, this new gorgonopsian specimen occurs in the uppermost Pristerognathus AZ (Smith and Keyser 1995); this suggests that its horizon of provenance is younger than ~260.41 Ma (late Capitanian) based on the age of the Pristerognathus AZ as derived from CA-TIMS U–Pb dates from reworked tuff beds in the Eastern Cape Province

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; gray siltstone

Size class: macrofossils
