Abstract

"Permian scallops of the genera Streblochondria and Guizhoupecten, family Streblochondriidae, are here revised with the aid of superb collections of silicified specimens from western Texas. The more specialized of the two genera, Guizhoupecten, shares several 'derived' characters with the post-Paleozoic family Pectinidae. This study illustrates the necessity of large, well-preserved collections for evaluating variable populations. Phylogenetic and ecological conclusions are deferred until we can properly document associated taxa"--P. [1].
