Abstract

Up to the present there was a gap from the Liassic to the Callovian time in the ichthyosaur record. A long - snouted ichthyosaur found in the Early Bajocian of Chacaico Sur (Northwestern Patagonia, Argentina) is the most complete ichthyosaur fossil of this age. This specimen is assigned to a new genus and species. A comparison of the new taxon with the other long-snouted ichthyosaurs reveals important differences in the mandible ratio, cranial proportions, and forelimb structure. Early Bajocian ammonites in the same stratum provide the age control.
