Guizhouichthyosaurus tangae (Cao et Luo in Yin et al., 2000; Shang and Li 2009; Maisch et al. 2015; Late Triassic) is an ichthyosaur derived from a sister to Platypterigius and basal to Shonisaurus popularis.

Guizhouichthyosaurus had very large fore flippers and a long narrow skull. The posterior skull (supratemporal + postfrontal + postorbital) are displaced in situ, reconstructed above). Some bones are relabeled.
