Marine reptiles,especially large-sized long-snout ichthyosaurs,are highly controversial in taxonomy in Guanling Biota(early Carnian,Guizhou,SW China).A large number of largesized long-snout ichthyosaur skeletons have been excavated from Guanling and adjacent areas since 2000.Totally 14 specimens were used for taxonomical research and morphological description in previous works,which were originally named as different genera and species(Yin et al.,2000:Gmr 009,Gmr 015; Li and You,2002:IVPP V 11865,V 11869; Chen and Cheng,2003:TR 00001,SPCV 30014; Maisch et al.,2006:GNP dq-46,D-41,dq-22; Pan et al.,2006:GMPKU P1062; Chen et al.,2007:SPCV 10305,10306; Shang and Li,2009:IVPP V 11853; Shang et al.,2012:IGGCAS 2005F001).Based on the similarity of cranial morphology,Shang et al.(2012) referred all of these specimens to one species Shastasaurus tangae.
