Pessopteryx is an extinct genus of ichthyosaur from the Early Triassic (Olenekian) of Svalbard, Norway.[1] The genus originally contained four species, P. nisseri, P. arctica, P. pinguis, and P. minor, which were named in 1910 by Carl Wiman.[2][3] Only P. nisseri is still considered valid; P. arctica and P. pinguis are considered nomina dubia while P. minor was reassigned to the tenuous genus Isfjordosaurus.[3] Omphalosaurus nisseri, Merriamosaurus hulkei, and Rotundopteryx hulkei are all junior synonyms of P. nisseri.[1]
