Here, we report the earliest fossil record of Bauhinia s.s., namely Bauhinia tibetensis Y. Gao et T. Su sp. nov., based on leaves from the latest Paleocene of the southern Tibetan region. Combined with palaeoecological niche simulations and ancestral state reconstruction, the new fossils suggested a Paleocene origin of Bauhinia s.s. in the Afrotropical realm that subsequently dispersed to the Neotropical and Indomalayan realms. Bauhinia tibetensis belongs to the Asian clade of Bauhinia s.s. that reached the southern Tibetan region from the Afrotropical realm via the Kohistan-Ladakh Island Arc in the early Paleocene. This clade spread to south-eastern China during the Oligocene and entered northern India during the Neogene or earlier. The discovery of the oldest Bauhinia s.s. from what is now the southern Tibetan Plateau updates our understanding of the biogeographical history of this genus and demonstrates that the Kohistan-Ladakh Island Arc is an ancient corridor for floristic interchange between Africa and India.Keywords: Bauhinia s.s.biogeographydiversificationPaleoceneleaf fossilpalaeoecological niche simulations AcknowledgementsWe thank the members of the Paleoecology Research Group from Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences (CAS) and colleagues from Kunming Institute of Botany, CAS for fossil collection works.

{"title":"<i>Gujaratia indica</i> , the oldest artiodactyl (Mammalia) from South Asia: new dental material and phylogenetic relationships","authors":"Abhay Rautela, Sunil Bajpai","doi":"10.1080/14772019.2023.2267553","DOIUrl":"https://doi.org/10.1080/14772019.2023.2267553","url":null,"abstract":"AbstractDiacodexeids are widely considered to be a paraphyletic group consisting of the oldest and most primitive artiodactyls that made their sudden appearance in all northern continents around the Palaeocene–Eocene boundary. In South Asia, the first record of artiodactyls is marked by the appearance of Gujaratia indica from the early Ypresian (∼55 Ma) Cambay Shale of the Vastan lignite mine, India, which is slightly younger than the oldest artiodactyls from Europe and North America. Here we describe new dental material of G. indica, documenting associated upper dentition, including P4, a new locus. Gujaratia (including G. pakistanensis and G. indica) is clearly distinct from all known diacodexeids in having the most triangular upper molars and lower molars with weaker paraconids. Cladistic analysis performed to assess the phylogenetic relationships of Gujaratia with other diacodexeids, dichobunoids, raoellids and pakicetids shows that Gujaratia is monophyletic while Diacodexis and Diacodexeidae are strongly polyphyletic. Gujaratia is found to be closer to the North American diacodexeids and D. gigasei and D. morrisi from Europe, which form a paraphyletic group. The European Diacodexis represents an unnatural grouping with D. antunesi being most closely related to a clade comprising dichobunids and homacodontids, and D. gazini and D. varleti occupying basal positions in a clade comprising raoellids and pakicetids. Dichobunidae is also recovered as a polyphyletic group whereas Homacodontidae is paraphyletic. Raoellids and pakicetids, long considered to be endemic to the Indian subcontinent, are monophyletic and without close affinities to Gujaratia, and appear to be more closely allied to some European dichobunoids, e.g., D. gazini, necessitating a reappraisal of current ideas about artiodactyl origins.Keywords: EoceneGujaratiaphylogenyDiacodexeidaeIndian subcontinent AcknowledgementsWe thank the two anonymous reviewers and the editors for their constructive comments which helped improve the manuscript.
