Description
Summary:Gronausaurus wegneri n. gen. n. sp. represents a newly discovered leptocleidid sauropterygian based on one individual from the Early Cretaceous (Berriasian) of Gronau in Westphalia, Germany. The holotype and only known specimen consists of a skeleton, which lacks most of the dermal skull bones, a large number of cervical vertebrae and distal limb elements. Gronausaurus wegneri is unique in having distinct cavities, the subdiapophyseal fossae, below the transverse processes of the pectoral and anterior dorsal vertebrae, that probably stabilised the bones against tensile forces of the rotator and levator muscles in the living animal.
