摘要	The Ginglymodi are a group of ray-finned fishes that make up one of three major subdivisions of the infraclass Neopterygii.Ex- tant ginglymodians are represented by gars,which inhabit freshwater environments of North and Central America and Cuba.Here, we report the discovery of well-preserved fossils of a new ginglymodian,Kyphosichthys grandei gen.et sp.nov.,from the Middle Triassic(Anisian)marine deposits(Guanling Formation)in Luoping,eastern Yunnan Province,China.The discovery documents the first known fossil record of highly deep-bodied ginglymodians,adding new information on the early morphological diversity of this group.The studies of functional morphology of extant deep-bodied fishes indicate that Kyphosichthys is not a fast swim- mer but has a good performance in precise maneuvering,representing a morphological adaptation to structurally complex habitats (e.g.thick macrophyte beds,rocky areas,or coral reefs),which differs from the other members of this group.A cladistic analysis with the new fish taxon included supports the hypothesis that the Ginglymodi are more closely related to the Halecomorphi than to the Teleostei.Represented by Felberia,Kyphosichthys,and Dapedium,a highly deep and short fish body type has inde- pendently evolved at least three times in the stem-group neopterygians,ginglymodians,and basal teleosts within the lower neop- terygians of the Triassic.
