List of ichthyosauromorph type specimens

Add links
From Wikipedia, the free encyclopedia

This list of ichthyosauromorph type specimens is a list of fossils serving as the official standard-bearers for inclusion in the species and genera of the reptile clade Ichthyosauromorpha (Hupehsuchia included). Type specimens are those which are definitionally members of biological taxa and additional specimens can only be "referred" to these taxa if an expert deems them sufficiently similar to the type.
