In this study, we focus on the Early Oligocene <em>Podocarpium</em> of the Huatugou area in the western Qaidam Basin, located in the northeastern of the Qinghai-Tibet Plateau (QTP). Through detailed morphological observation and comparison, they are identified as a new species, named <em>Podocarpium minicum</em> C. Xie et D.-F. Yan sp. nov., characterized by irregularly oval pod shape, a sharply constricted apex, extremely small size, and the ratio of stipe/valve length ratio is more than 2. Based on the available fossil record, it is hypothesized that this genus may have originated in the Indian subcontinent. After migrating into the QTP, it underwent rapid radiation and further dispersed across Eurasia. The discovery of <em>P. minicum</em> sp. nov. suggests that the genus may have possessed relatively high diversity and a broad distribution in the Qaidam Basin. This fossil record reveals a potential “multi-track evolutionary mechanism” employed by the genus in response to environmental changes, while also reflecting that the EOT (Eocene–Oligocene Transition) may have indirectly influenced the climate of study area. This finding not only provides important evidence for understanding the evolutionary and distributional history of the genus but also offers further support for the hypothesis that it spread into Europe via a high-latitude route crossing the Turgai Strait.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"346 ","pages":"Article 105494"},"PeriodicalIF":1.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145797682","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}

The sequence of the developmental stages in <em>Lupinus</em> exine has been analyzed based on the above idea. To check the above idea, a modeling of exine-like pattern was carried out <em>in vitro</em> with colloidal mixtures of surfactants, analogous to those in natural anther. Flower buds of different size were collected from the Garden of the Komarov Botanical Institute, St. Petersburg, for several seasons. After fixation of the <em>Lupinus</em> material, sections were prepared and examined with TEM and SEM. For modeling exine development <em>in vitro</em>, our own method was used to obtain simulations. The successive developmental structures observed within the microspore periplasmic space have occurred to be the same as in the typical micellar self-assembly sequence in colloidal system of surfactants. Simultaneously, signs of phase separation in the fluid of the periplasmic space were evident. As was expected, several exine-like simulations of the <em>Lupinus</em> exine structures were obtained in our experiments. Pure physicochemical processes are capable to build exine-like patterns. Hence, physical processes share influence on exine development with genome.

This exceptional preservation enables a preliminary <em>ex situ</em> study to describe their modes of preservation and reconstruct the broad taphonomic pathways leading to the fossilization of these ovulate cones. The systematic observation of Belgian Lower Cretaceous pinaceous material has led to the recognition of four distinct types of preservation, each reflecting different taphonomic histories, along with marked differences between geographically close localities. A comparative analysis with ovulate cones of extant Pinaceae deposited in modern forest ecosystems was conducted to establish links between cone degradation patterns and environmental conditions. These comparisons with present-day degradation processes in natural environments support a detailed interpretation of one specific fossilization pathway (type I), corresponding to cones deposited in a forest environment and subsequently subjected to rapid burial. The <em>ex situ</em> examination of this historical collection, despite the absence of an accurate stratigraphic context, provides valuable insights into the reconstruction of broad but nonetheless informative taphonomic features that may relate to past environmental conditions. These results provide new information about the paleoenvironmental context during the Early Cretaceous in this region. Altogether, these findings contribute new and significant information regarding the ecology and environmental settings of early Pinaceae, as well as other organisms preserved within the same sedimentary contexts, thereby enriching our understanding of Barremian–Albian ecosystems in the Wealden facies of Belgium.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"346 ","pages":"Article 105495"},"PeriodicalIF":1.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145797689","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}
