Abstract

PAGANI, María Alejandra. Carboniferous and Permian bivalves from Patagonia (Chubut, Argentina): Part V: Families Trigoniidae, Permophoridae, Cardiniidae, Crassatellidae, Pholadomyidae, Sanguinolitidae and Megadesmidae. Conclusions. Ameghiniana [online]. 2006, vol.43, n.3, pp.539-556. ISSN 1851-8044.

A thorough systematic analysis on the bivalve fauna of the Upper Paleozoic of the Tepuel-Genoa Basin (Chubut Province, Argentina) is performed, as a contribution to the knowledge of early Permian faunas of Argentina. This last part comprises the families Trigoniidae, Permophoridae, Cardiniidae, Crassatellidae, Pholadomyidae, Sanguinolitidae, Megadesmidae, and conclusions of all study. The abundant well preserved specimens allowed the recognition of the new species Pleurophorella elongata n. sp. New records of Permophorus sp., Lyroschizodus? sp., Oriocrassatella sp., Cosmomya (Palaeocosmomya) sp., Exochorhynchus sp. and Pyramus sp. are also included. On the basis of new material from the Tepuel-Genoa Basin, the diagnoses of Cosmomya (Palaeocosmomya) chubutensis González, Pyramus tehuelchis González, and Pyramus primigenius González are revised. In addition, the descriptions of these and other previously known species (Cypricardinia? elegantula Dickins, Sanguinolites freytesi González, Sanguinolites turneri González and Myofossa antiqua González) are supplemented by new information and their geographical ranges are expanded.
