{"title":"Mesozoic stem-group zoroasterid sea stars imply a delayed radiation of the crown group and adaptation to the deep seas","authors":"Marine Fau, Loïc Villier","doi":"10.1080/14772019.2023.2243268","DOIUrl":"https://doi.org/10.1080/14772019.2023.2243268","url":null,"abstract":"AbstractThe family Zoroasteridae is a clade of extant sea stars found exclusively in deep marine environments (i.e. bathyal environments deeper than 200 m). In the fossil record, seven species have been compared and/or assigned to the Zoroasteridae, on a time span ranging from the Middle Jurassic to the Miocene. This study describes a new taxon, Viridisaster guerangeri gen. et sp. nov., from the Cenomanian of Le Mans (Sarthe, France) and reappraises two Mesozoic species, the Jurassic Terminaster cancriformis and the Early Cretaceous Protothyraster priscus. To test the relationships of the putative fossil zoroasterids with modern taxa, a phylogenetic analysis was performed combining six of the best-known fossil species and 29 forcipulatacean species, including four Zoroasteridae. Many of the characters that define the extant Zoroasteridae do not appear in the fossil record before the Cenozoic. The family name is maintained for the crown group only. The family Terminasteridae, that accounted for the genera Terminaster and Alkaidia, is found paraphyletic and is rejected here. The order Zorocallida, initially erected for the family Zoroasteridae only, is redefined as the sister clade to the Forcipulatida that includes the crown-group Zoroasteridae and its stem relatives. Mesozoic Zorocallida are small in size compared to the Cenozoic Zorocallida, and they express morphological characters that are typical of juvenile Zoroasteridae; thus, the emergence of modern forms is likely associated with peramorphic evolution. The palaeoecology of the Zoroasteridae and their restriction to deep-sea environments after the Eocene is discussed.http://zoobank.org/urn:lsid:zoobank.org:pub:1755AFC6-198F-45F2-A2F6-011EAC6BE10FKeywords: CretaceousAsteroideaEchinodermataphylogenynew taxon AcknowledgementsThe authors are grateful to the collection managers who facilitated access to the specimens: Nicolas Morel (MHNLM); Walter Etter and Sergio Kühni (NMB Basel); Timothy A.

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.
