Anderson, J. M.
The charts presented here (i.e. charts 23-35) are intended to form part of a series with those (i.e. charts 1-22) compiled by H. M. Anderson and J. M. Anderson as a supplement to Palaeontologia Africana, Volume 13, 1970' (see bibliography). Charts 1- 22 were presented under the title "A preliminary review of the biostratigraphy of the uppermost Permian, Triassic and lowermost Jurassic of Gondwanaland". Further charts are to follow and will be numbered from 36 onwards.
