Thus, this species has long been considered significant in stratigraphic correlation of non-marine sequences. However, previous studies of <em>P. ptilum</em> have been mostly focused on the morphological characteristics of its foliages, a complete biological feature, particularly the epidermal anatomy, remains poorly understood. Here, we show detailed epidermal anatomies of <em>P. ptilum</em> based on well-preserved cuticular specimens from the Upper Triassic of Sichuan Province, Southwest China. <em>Pterophyllum ptilum</em> is characterised by petiolate leaves with small lateral leaflets, which possess contracted bases and bicuspid apices with five to eight parallel veins and syndetocheilic type stomata. In the leaflets, the stomata are only present on the abaxial surface, whereas the stomata are present on both the abaxial and adaxial surfaces of the rachis. Both the adaxial and abaxial leaflet surfaces can be divided into costal and intercostal fields. The epidermal cells in the costal fields are elongated rectangular but shortened rectangular in the intercostal fields. The stomata are only present in the intercostal fields of the abaxial leaflet surface. On the rachis, the epidermal cells are all elongated rectangular and arranged tightly in vertical files. Based on a thorough comparison of fossil records and observation of extant cycads, we propose that the bicuspid leaflet apices of <em>P. ptilum</em> may resulted from herbivorous arthropod apical feeding damage. Fossil records reveal that <em>P. ptilum</em> were primarily preserved in coastal plain, deltaic, and tidal flat environments in the South China Block; the absence of papillae and hairs in the present specimens may suggest a relatively more humid local environment.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"339 ","pages":"Article 105351"},"PeriodicalIF":1.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143851589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fossil evidence offers unique insights into the historical biogeography and evolutionary trajectories of endemic taxa, particularly in biodiversity-rich regions like northeast India and the Western Ghats. This study reports the discovery of two <em>Nothopegia</em> species (Anacardiaceae) from late Oligocene sediments in the Makum Coalfield, Assam, northeast India. These fossils represent the earliest global record of the genus and display striking morphological similarities to the extant <em>Nothopegia travancorica</em> and <em>N. castaneifolia</em>, currently restricted to the Western Ghats, indicating a significant biogeographic shift over millions of years. Paleoclimatic and paleolatitudinal reconstructions suggest that the late Oligocene climate of northeast India mirrored the present-day equable climate of the Western Ghats, enabling the survival of <em>Nothopegia</em> in the region. However, the uplift of the Himalayan-Tibetan Plateau and a pronounced decline in the cold month mean temperature (CMMT) across northern and northeastern India likely drove the extinction of <em>Nothopegia</em> from these areas, confining it to the warmer environments of the Western Ghats. Present fossil evidence, along with previous fossil records of other plant taxa, underscores deep-time floristic connectivity between northeast India and the Western Ghats, likely facilitated by evergreen Paleogene forest corridors. These findings illuminate the biogeographic history of megadiverse ecosystems of South Asia and highlight the interplay between climatic shifts and geological events in shaping endemic biodiversity.

Its evolutionary history in bamboos remains poorly understood due to limited fossil evidence, with only a single previously documented specimen of a preserved node. Furthermore, the evolutionary ecology and paleoclimatic adaptations of bamboos during the Quaternary in Asia remain unclear due to a lack of fossil records. This study introduces <em>Chimonobambusa manipurensis</em> sp. nov., a well-preserved thorny bamboo fossil from the late Pleistocene of eastern India, marking the first Asian fossil record of thorny bamboo and the first Quaternary record from Asia. The fossil features nodes, internodes, nodal buds, and thorn scars, offering novel insights into bamboo spinescence and nodal morphology. <em>C. manipurensis</em> displays three well-preserved nodes, two complete internodes, prominently conserved nodal buds, and 3–4 thorn base scars along each nodal rim. Morphologically, it shares traits seen in modern <em>Chimonobambusa</em> Makino and is placed within the same genus. Together with a Pliocene–Pleistocene thorny bamboo record from Peru, this discovery suggests spinescence in bamboos likely emerged during the Neogene, with evolutionary adaptations continuing into the Pleistocene potentially as an adaptation to changing climatic conditions and increased herbivory pressures. Furthermore, it suggests that bamboos during Quaternary time in Asia were growing under warm and humid climatic conditions.
