Figure 3 in Morphological perspective on the classification and evolution of Recent Pterioidea (Mollusca: Bivalvia)

Figure 3. Previous ideas on the phylogeny of the Pterioidea. A, the phylogeny of the 'Aviculidae and their allies' by Jackson (1890: 391) after his genealogical table. Only the relevant part of the tree is shown. For clarity, outdated generic names are replaced with currently accepted names and the genera of Pinnoidea, Pseudomonotidae, Inoceramidae, and Ostreoidea are collapsed without altering the original topology. The Recent pterioidean taxa, the main subject of the present work, are highlighted in bold. The non-pterioidean taxa having their origin in Jackson's Pteria have been removed in subsequent revisions, as indicated in Table 1. B, proposed sister groups of the Pterioidea (see text for details).
