Hauffiopteryx

Hauffiopteryx is an extinct genus of ichthyosaur known from Germany, Luxembourg, Switzerland and Somerset of the United Kingdom. Two species are known: H. typicus and H. altera.

==History of study== thumb|left|Front of H. typicus fossil Hauffiopteryx was first described by Michael W. Maisch on the basis of some specimens that previously referred to Stenopterygius hauffianus. Maisch found that the lectotype of S. hauffianus can be determined as Stenopterygius cf. S. quadriscissus at best, and therefore this species should be considered a nomen dubium. He also found out that most specimens previously referred to S. hauffianus can be referred to S. quadriscissus, while the rest belongs to a highly distinctive new taxon that can't be referred to any valid species of Stenopterygius.
