sp. nov., from the Lower Cretaceous (probably Upper Hauterivian) of Germany. The material …

The two plesiosauroid species from the Posidonia shale of Holzmaden,'Plesiosaurus'

An almost complete postcranial skeleton recovered from late Maastrichtian beds of central

Though the Maastrichtian Phosphates of Morocco have yielded very rich marine vertebrate
assemblages, plesiosaurs remain very scarce in these strata. The only hitherto recognized …

Elasmosaurids are a monophyletic group of cosmopolitan plesiosaurs with extremely long
necks. Although abundant elasmosaurid material has been collected from the Upper …

Discussion—The slender morphology of tooth type A and the tightly packed pattern of
longitudinal ridges are diagnostic among Lower Jurassic plesiosaurs restricted to …

The systematics of elasmosaurids are not well resolved partially because of the scarcity of
well-preserved skull material. Among Weddellian elasmosaurids, one exception to this is the …

Three specimens of elasmosaurid plesiosaurs (Sauropterygia, Plesiosauria) from Upper
