Sundays River, east bank (Jurassic to of South Africa)

Also known as Site 15, Umfuleni

Where: Eastern Cape, South Africa (33.5° S, 25.5° E: paleocoordinates 44.2° S, 12.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Kirkwood Formation (Uitenhage Group), Tithonian to Tithonian (152.1 - 132.9 Ma)

• Kirkwood Fm. underlies the Sundays River Fm. which has been dated to Valanginian–Hauterivian based on biostratigraphic data (∼139–131 Ma; McLachlan and McMillan, 1976, Ross et al., 1999, Gomez et al., 2002, McMillan, 2003, Shone, 2006, Walker et al., 2012). Muir et al. 2017 state "Microfossil assemblages from the Bethelsdorp and Colchester Members in the lower part of the Kirkwood Formation of the Algoa Basin are dated as Tithonian (McMillan et al., 1997; McMillan, 2010), whereas the uppermost parts are inferred to be Lower Cretaceous in age based on a probable temporal equivalence with the lower part of the Valanginian – Hauterivian Sundays River Formation (McLachlan and McMillan, 1976; Shone, 1978; McMillan, 2003)."

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; fine-grained mudstone

• "fine-grained mudstone"

Size classes: macrofossils, mesofossils
