| Summary: | Figure 5. Schematic representation of the palaeognath ancestor in undivided Gondwana at 152 million years ago (Mya) and its distribution across divisions of the continent at 66 Mya according to the phylogeny presented here, with approximate dates of separation indicated in white type. It is assumed, based on the shape of the phylogeny, that ancestors of the South American taxa were present on the South America-Antarctica-Australasia fragment of Gondwana, rather than being the direct result of separation from Africa. Fossil palaeognath remains in Antarctica are not well enough characterized to fit into this phylogeny (Tambussi et al., 1994) but are denoted with a question mark. Maps are modified from the Paleomap project (Scotese, 2001). : Published as part of Johnston, Peter, 2011, New morphological evidence supports congruent phylogenies and Gondwana vicariance for palaeognathous birds, pp. 959-982 in Zoological Journal of the Linnean Society 163 (3) on page 969, DOI: 10.1111/j.1096-3642.2011.00730.x, http://zenodo.org/record/5442063 |
