Taxons
Chacaicosaurus
Diagram of the known material of the forefin of MOZ 5803, the holotype and only known specimen of the Bajocian Argentine ichthyosaur Chacaicosaurus cayi, as preserved, following Fernández (1994). The partial humerus and isolated phalanges were not found in articulation with the rest of the limb and are therefore not included here.
