}ABSTRACT
Here we report on a new basal elasmosaurid plesiosaurian, Lagenanectes richterae, gen. et sp. nov., from the Lower Cretaceous (probably Upper Hauterivian) of Germany. The material includes a partial skull (cranium and mandible), the atlas-axis complex, additional cervical vertebrae, caudal vertebrae, an ilium, and limb elements. The basioccipital and atlas intercentrum are pathologically deformed, probably due to an osteomyelitic infection. Two potential autapomorphies were found in…

A new elasmosaurid is described from the upper Hauterivian (Lower Cretaceous) of Ulyanovsk (European Russia) and its shape suggests multiple episodes of elongation and shortening, however, the precise patterns are obscured by an unstable phylogenetic signal.
