Boplaas Formation (3rd Sandstone), Grootrivier (Devonian of South Africa)

Where: South Africa (32.6° S, 19.4° E: paleocoordinates 65.7° S, 154.3° W)

• coordinate stated in text

• local area-level geographic resolution

When: Boplaas Formation (Bokkeveld Group), Eifelian (393.3 - 387.7 Ma)

• Age call from ref. 9618.

• formation-level stratigraphic resolution

Environment/lithology: marine; fine-grained, medium, intraclastic sandstone

• Ref. 9618 gives interpretation of Bokkeveld Group as a series of shallowing-upward packages, with argillaceous unit below and arenaceous unit above. 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 "sandstone". Ref. 9617, for formation as a whole, cites "Sandstone, fine- to medium-grained, thin- to thick-bedded, horizontal and ripple laminated, planar and trough cross-bedded, thin intraclast lenses, as well as numerous thin lenses of plant fragments"
