Key to symbols and footnotes: +, present; −, absent; ±, vestigial; ?, unknown; aQuality of specimen preservation not sufficient to determine presence/absence; bData from [48] and A.V. Balushkin (personal communication to J.T. Eastman on the presence of floating posterior pleural ribs in Halaphritis); cLarvae of 16.5 mm SL have two nostrils ([76]: p. 64); dIn agreement with ([23] p. 43–44), ectopterygoid teeth were present in the three alizarin-stained specimens we examined; eDistal part of choroid fissure persists in Gobionotothen gibberifrons and Dolloidraco longedorsalis [111]
