Journal Article
Lithostratigraphy and sedimentology of the Middle Devonian Tra-Tra Formation, including the Grootrivier Member (Bokkeveld Group, Cape Supergroup), South Africa Available to Purchase
Journal: South African Journal of Geology
Publisher: Geological Society of South Africa
Published: 01 September 2020
South African Journal of Geology (2020) 123 (3): 381–398.
...C.R. Penn-Clarke; J.N. Theron Abstract The Tra-Tra Formation is a predominantly argillaceous, shallow marine to paralic sedimentary succession of Eifelian (Middle Devonian) age within the Bokkeveld Group (Cape Supergroup) that crops out extensively within the Cape Fold Belt of South Africa...
Journal Article
Eifelian–Givetian (Middle Devonian) high-paleolatitude storm- and wave-dominated shallow-marine depositional systems from the Bidouw Subgroup (Bokkeveld Group) of South Africa Available to Purchase
Journal: Journal of Sedimentary Research
Publisher: SEPM Society for Sedimentary Geology
Published: 27 November 2019
Journal of Sedimentary Research (2019) 89 (11): 1140–1170.
... previously been proposed for the Bokkeveld Group. Sequence-stratigraphic analysis of the Bidouw Subgroup suggests that although sedimentation occurred during two large-scale second-order transgressive events, the succession was predominantly regressive. Third-order and fourth-order transgressive–regressive...

TAPHONOMY AND PALEOECOLOGY OF AN OPHIUROID-STYLOPHORAN OBRUTION DEPOSIT FROM THE LOWER DEVONIAN BOKKEVELD GROUP, SOUTH AFRICA Available to Purchase
Journal: PALAIOS
Publisher: SEPM Society for Sedimentary Geology
Published: 16 April 2019
PALAIOS (2019) 34 (4): 212–228.
...MHAIRI REID; WENDY L. TAYLOR; CARLTON E. BRETT; AARON W. HUNTER; EMESE M. BORDY ABSTRACT The taphonomy of a well preserved ophiuroid-stylophoran assemblage from the Bokkeveld Group, Lower Devonian of South Africa is described using micro-CT scanning techniques. This assemblage provides a taphonomic...
