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.
