Permian pelecypods from Tunisia. American Museum novitates ; no. 2686

Abstract

"Fifteen late Permian pelecypod species belonging to 15 genera and 13 families are described from Tunisia. Shikamaia ? ogulineci, a remarkable ambonychiacean, Gigantocyclus zidensis, a lucinid of surprisingly modern aspect, and a new species, Lyroschizodus djemelensis are morphologically unusual elements of the fauna. A new non-byssate pterinopectinid, Denguiria azzouzi, new genus and new species, is described. A minor element of an extraordinarily rich assemblage of marine invertebrates dominated by reef-building calcareous sponges, the pelecypods show surprisingly little resemblance to contemporaneous assemblages of other areas"--p.
