...JUDY A. MASSARE; JACK M. CALLAWAY Abstract The resolution of the problem of ichthyosaurian affinities has been complicated and prolonged by an emphasis on the morphology of Jurassic ichthyosaurs, some 30 to 40 m.y. younger than the earliest known species.

In A. bitumineus , poor preservation makes it unclear whether the supratemporal or the postfrontal form the anterior margin of the temporal fenestra. However, a review of the parvipelvian ichthyosaurs for which the dorsal skull roof is well known...

... (Quenstedt), long considered a longipinnate, is herein shown to have closer phenetic affinity with latipinnate ichthyosaurs. The close phenetic affinity between the skulls of P . americanus and the undescribed Swiss ichthyosaur is inconsistent with currently held views of cranial evolution in ichthyosaurs...
