Gydo Formation (1st Shale), Prince Albert area (Devonian of South Africa)

Where: South Africa (33.3° S, 21.8° E: paleocoordinates 59.5° S, 151.9° W)

• coordinate stated in text

• local area-level geographic resolution

When: Gydo Formation (Bokkeveld Group), Emsian (407.6 - 393.3 Ma)

• Age call from ref. 9618

• formation-level stratigraphic resolution

Environment/lithology: marine; bioturbated mudstone and bioturbated siltstone

• Ref. 9618 gives interpretation of Bokkeveld Group as a series of shallowing-upward packages, with argillaceous unit below and arenaceous unit above. Gydo Formation, as the "first shale", is the lowermost argillaceous unit. The shallowing upward sequence is interpreted as representing environments from the shelf up to deltaic systems. Most fossils come from lower mudstones, often in lenses.

• Ref. 9616 refers only to "shale". Ref. 9617, for formation as a whole, cites "Mudstones and siltstones and minor thin-bedded sandstone, scattered fossiliferous nodules and lenses, lenticular bedding, abundant bioturbation."

Collection methods: Author gives numbers from personal collections, which are said to have some bearing on actual abundances.
