AbstractTanystropheidae is a clade of early archosauromorphs with high morphological disparity and a wide geographical distribution. The origin and early radiation of Tanystropheidae are still incompletely understood. Here we report Luxisaurus terrestris gen. et sp. nov., a new archosauromorph collected from the marine Upper Member of Guanling Formation (Pelsonian substage, Anisian, Middle Triassic) in Luxi County, Yunnan Province, China, and phylogenetically recovered as a tanystropheid. The morphology of Luxisaurus is consistent with a terrestrial lifestyle. This is the first occurrence of a tanystropheid found from the Anisian Guanling Formation in SW China and also the earliest tanystropheid from the eastern Tethys. Phylogenetic analysis shows that Dinocephalosauridae forms the sister group of Tanystropheidae, Fuyuansaurus occupies the most basal position in Tanystropheidae, and Luxisaurus forms the sister group to a clade consisting of all other tanystropheids. Considering that Fuyuansaurus and Luxisaurus are found exclusively in South China, we hypothesize that Tanystropheidae originated in the Early Triassic of South China and then dispersed globally. The discovery of Early Triassic tanystropheids in South China is needed to further support this hypothesis. The discovery of Luxisaurus expands the stratigraphical and geographical distribution of Tanystropheidae, and provides new insights into the origin and early radiation of the clade.http://zoobank.org/urn:lsid:zoobank.org:pub:07DE12AC-8AE7-48F0-8BAD-0B73F04C0858Keywords: marine reptileDinocephalosauridaephylogenyGuanling Formation AcknowledgementsWe thank Y.

摘要蝶科是一种形态差异大、地理分布广泛的早期始祖形动物分支。坦氏蝇科的起源和早期辐射仍不完全清楚。本文报道了在中国云南省鲁溪县中三叠世安尼期海相关岭组上段(Pelsonian亚阶段)中发现的一种新的原蜥脚类Luxisaurus terrestris gen. et sp. nov.。Luxisaurus的形态与陆地上的生活方式一致。这是在中国西南部安尼西亚关岭组首次发现的剑鞘类动物，也是在特提斯东部最早发现的剑鞘类动物。系统发育分析表明，龙头龙科是剑齿虎科的姊妹类群，福源龙在剑齿虎科中处于最基础的位置，Luxisaurus是剑齿虎科所有分支的姊妹类群。考虑到福源龙和Luxisaurus仅在华南地区发现，我们推测Tanystropheidae起源于华南早三叠世，然后在全球范围内扩散。华南地区早三叠世tanystropheids的发现需要进一步支持这一假设。Luxisaurus的发现扩大了Tanystropheidae的地层和地理分布，并为该分支的起源和早期辐射提供了新的见解。http://zoobank.org/urn:lsid:zoobank.org:pub:07DE12AC-8AE7-48F0-8BAD-0B73F04C0858Keywords:我们感谢Hu Y.

The taxonomy of Cretaceous cirripedes referred to the sessile orders Brachylepadomorpha and Verrucomorpha is revised. New taxa include the brachylepadid genera Crithmumlepas (type species C. hoensis sp. nov., C. aycliffensis sp. nov.) and Calvatilepas (type species C. recurvus sp. nov.). The family Pycnolepadidae nov. is established (constituent genera Pycnolepas, Faxelepas) and Pycnolepas batchelorum sp. nov. is described; a new eoverrucid species, E. barringtonensis sp. nov. is erected. Cladistic analysis of 48 characters of 18 operational taxonomic units, including 16 in-group sessile taxa yielded a consensus tree showing the strongly supported monophyly of Brachylepadomorpha + Verrucomorpha + Balanomorpha. It is recommended that the Order Brachylepadomorpha is abandoned, and its constituent families are identified as, respectively, stem group Verrucomorpha (Pycnolepadidae) and stem group Balanomorpha (Brachylepadidae). The sister-group relationship of Verrucomorpha and Balanomorpha, identified from many molecular studies, is confirmed from shell morphological data. The Neolepadoidea are shown to closely parallel the sessile adaptations of verrucomorphs and balanomorphs. The fossil record of key segments of cirripede evolution is demonstrated to be remarkably, and surprisingly, complete.
