Shell microstructure of the basal pectinid Pleuronectites laevigatus: implications for pectinoid phylogeny (Mollusca: Bivalvia: Pteriomorphia)


Carter, J G; Hautmann, M (2011). Shell microstructure of the basal pectinid Pleuronectites laevigatus: implications for pectinoid phylogeny (Mollusca: Bivalvia: Pteriomorphia). Journal of Paleontology, 85(3):464-467.

Abstract

New shell microstructure data for the Triassic pectinid Pleuronectites reinforce shell morphological data suggesting that its family Pectinidae was derived from the superfamily Aviculopectinoidea and not from the Pernopectinidae-Entolioidesidae-Entoliidae clade. This would make the superfamily Pectinoidea, as defined by recent authors, polyphyletic. This would also imply that alivincular-alate ligaments evolved independently in the Pernopectinidae-Entolioidesidae-Entolidae and Pectinidae clades.
