Mh. Stephenson et D. Mclean, International correlation of Early Permian palynofloras from the Karoo sediments of Morupule, Botswana, S AFR J GEO, 102(1), 1999, pp. 3-14
Palynological assemblages of the lower Karoo Morupule Main Seam of Botswana
are similar to those of the Striatopodocarpites fusus Biozone of the Colli
e Basin, Western Australia and the 3a Microfloral Biozone of the northern K
aroo Basin, South Africa. This indicates an Aktastinian (Early Permian) age
for the strata of Morupule.
