Bivalves from the carboniferous glacial deposits of central Patagonia

Abstract

Karbonische Ablagerungen von Zentral-Patagonien (Argentinien) liefern wichtige Hinweise zu Reichweite und Herkunft verschiedener Angehöriger der endemischen Bivalven-Fauna von Gondwana. Allerdings ist nur sehr wenig Material zu interessanten Taxa verfügbar, das darüber hinaus nur unvollständig erhalten ist, sodass Beschreibungen unvollständig bleiben. Die neue Gattung Waterhouseus und vier neue Arten werden beschrieben: Waterhouseus keideli n. sp., Streblopteria? n. sp., Megadesmus? n. sp. und Myonia? prinsi n. sp. Die Beschreibung der Morphologie von Merismopteria salinensis González kann durch Revision präzisiert werden. Neue Vorkommen werden für zwei bereits bekannte Arten, Waterhouseus tepuelensis (González, 1969) und Pyramus primigenius González, 1972, vorgestellt. Fünf weitere Arten, Nuculopsis sp., Leptodesma (Leiopteria) sp., Myonia? sp. Pyramus? sp. und Amosius sp. werden wegen ihrer unzureichenden Erhaltung unter offener Nomenklatur beschrieben.

Carboniferous deposits of central Patagonia afford important evidence on the range and origin of various components of the endemic bivalve fauna of Gondwana, but the available material of some interesting forms is unfortunately scarce and incomplete remains that allow a very limited description. A new genus, Waterhouseus, and four new species are described: Waterhouseus keideli n. sp., Streblopteria? n. sp., Megadesmus? n. sp. and Myonia? prinsi n. sp. The morphology of Merismopteria salinensis González is amplified after revision. New occurrences are reported for two previously known species: Waterhouseus tepuelensis (González, 1969) and Pyramus primigenius González, 1972. Five further species: Nuculopsis sp., Leptodesma (Leiopteria) sp., Myonia? sp. Pyramus? sp. and Amosius sp. are left innominate because insufficiently known.
