My initial browsing of the new edition of Claus Nielsen’s Animal Evolution could scarcely have produced a bigger surprise. Opening the book from the back I first read the last line of the last chapter on molecular phylogeny: “The evolutionary scenario pictured in fig. 57.2 [a molecular cladogram based on 18S rDNA sequences] is fully compatible with the phylogeny proposed on morphological evidence in this book...” (p. 519). Imagine the surprise! Anyone even marginally familiar with recent developments in higher-level animal phylogenetics will be aware of some major conflicting... |

These species are herein described as the palaeostomatopod Bairdops beargulchensis Schram & Horner, 1978 and a new species of archaeostomatopod, Tyrannophontes acanthocercus. quite distinct from the Pennsylvanian archaeostomatopod Tyrannophontes acanthocercus is T. theridion from the Essex fauna (Mazon Creek), with which it was originally compared. Bairdops beargulchensis is very similar to the Mississippian palaeostomatopod, B. elegans, from the Scottish Glencartholm fauna. A previously... |
