Postcranial morphology of a basal Pistosauroidea (Sauropterygia) from
the Lower Muschelkalk of Winterswijk, The Netherlands.
Paläontologische Zeitschrift (advance online publication)
Two partial postcranial skeletons from the Lower Muschelkalk (early
Anisian) of Winterswijk, The Netherlands, are described in detail. The
specimens were assigned to basal Pistosauroidea, presumably to cf.
Cymatosaurus or a closely related taxon. Cymatosaurus is currently the
earliest member of the Pistosauroidea and is only known from skull
material. Taxonomical assignment is based on humerus morphology and
histology, and on morphological differences from other Sauropterygia
(Nothosauria and Pachypleurosauria).
