| 英文摘要 | Rhipidistians comprise dipnomorphs (the lungfish lineage) and tetrapodomorphs (the tetrapod lineage). Arquatichthys porosus Lu and Zhu, 2008 is a Pragian dipnomorph from the Posongchong Formation of Zhaotong, Yunnan, South China (similar to 409 million years ago, Early Devonian), previously represented by a lower jaw and few scattered scales. Here we describe a newly-discovered postparietal shield of Arquatichthys by means of high-resolution computed tomography. The cranial morphology of Arquatichthys resembles that of the basal dipnomorph Powichthys in having more than two supratemporal bones each side, more than one row of openings for sensory canals on the marginal bones, and a straight posterior margin of the shield. An intricate occipital artery system is present between the skull roof and neurocranium, as in Youngolepis and the tetrapodomorph Eusthenopteron. The discovery of the postparietal shield of Arquatichthys adds new evidence in the cranial evolution of rhipidistians, and helps to improve our understanding of the character transformations during the early diversification of rhipidistians.
