Ho ka etsahala hore ebe e ne e le “se seng sa lihahabi tse khōloanyane tsa metsing” tse neng li phela tikolohong ea tsona ka nako eo, ho latela mongoli ea ka sehloohong oa phuputso eo Andrzej Wolniewicz, setsebi sa thuto ea lintho tsa khale Univesithing ea Hefei ea Theknoloji e Chaena le Poland Academy of Sciences.
Ho fihlela joale, ea khale ka ho fetisisa li-saurosphargids e qalile lilemong tse ka bang limilione tse 245 tse fetileng nakong ea bohareng ba Triassic. Bo-rasaense ha ba tsebe hore na P. yingzishanensis e bile moholo-holo ho tsena hamorao li-saurosphargids kapa leloko le arohaneng, Wolniewicz o itse. Empa moralo oa kakaretso oa mefuta e sa tsoa hlalosoa e fana ka maikutlo a matla a hore sehlopha sohle se ka be se ile sa aroloa ka tsela e fosahetseng pele, a eketsa.

Ka lebaka leo, bangoli ba thuto ba hlahisitse hore li-saurosphargids e lokela ho hlophisoa bocha e le sehlopha se senyenyane sa li-sauropterygians.
Bafuputsi ba boetse ba lumela hore li-sauropterygians le lihlopha tse ling tsa lihahabi tsa leoatleng, tse kang ichthyosauromorphs, tse kenyelletsang li-ichthyosaurs le thalattosaurs, li ka amana haufi-ufi le li-clade Archelosauria - sehlopha se kenyelletsang likolopata tse phelang le tse timetseng le li-archosaurs, tse kenyelletsang li-crocodilians le linonyana - hofeta kamoo ho neng ho nahanoa pele.
