Also known as Gaiasia jennyae type locality

Where: Namibia (20.7° S, 14.2° E: paleocoordinates 51.2° S, 30.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Gai-As Formation, Cisuralian (298.9 - 273.0 Ma)

• The Cisuralian age is based on a U–Pb SHRIMP date (272 ± 1.8 million years ago (Ma), Roadian) of the uppermost beds of the unit and the age of the underlying unit (Artiskian, about 285 Ma).

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, medium-grained, red, argillaceous mudstone and siltstone

Size class: macrofossils

• The Gaiasia type specimen (F-1528) comprising the skull with articulated lower jaw and fullyarticulated partial axial skeleton was preserved dorsal-up and completely enveloped with calcareous nodular material.
