David, J.M., Simões, M.G., Anelli, L.E., Rohn, R. and Holzfoerster, F. 2010. Permian bivalve molluscs from the Gai-As Formation, northern Namibia: systematics, taphonomy and biostratigraphy. Alcheringa: An Australasian Journal of Palaeontology, DOI: 10.1080/03115518.2011.538908


Description:

Permian bivalve molluscs from the Gai-As Formation, northern Namibia: systematics, taphonomy and biostratigraphy.

Summary / Notes:

Fossil bivalves from two horizons in the Gai-As Formation of NW Namibia are tentatively correlated with mid-Permian taxa of the Passa Dois Group of Brazil, supporting the concept that the Parana' Basin extended into Africa. The Namibian fauna includes a new genus and species, Huabiella compressa, which was previously confused with Brazilian taxa. The taphonomy of the bivalve-rich strata indicates deposition under the influence of episodic events, such as storms. The Gai-As Formation directly overlies the mesosaurid-bearing deposits of the Huab Formation, indicating a significant unconformity when compared with the more complete succession of the Passa Dois Group, Parana' Basin, Brazil. The studied bivalve assemblages are no younger than 265+2.5Ma (mid-Permian), based on U/Pb radiometric dating of zircons from tuffs. Keywords: Bivalvia, Megadesmidae, Permian, Huab area, Gai-As Formation, biostratigraphy, Rio do Rasto Formation.
