Although the geologically instantaneous effects of the Chicxulub impact better explain the KPB catastrophic mass extinction, refinement of geochemical and micropaleontological proxies contributes to assessing the actual role of the Deccan volcanism in environmental changes across the KPB. Furthermore, cyclostratigraphy is being used to evaluate the role of orbital forcing on climate, and to refine age models. In this paper, we evaluate the climate and environmental changes across the KPB (66.100–65.350 Ma) from a global perspective, exploring several proxies from the Pacific, Atlantic and Tethyan realms: bulk δ<sup>18</sup>O and δ<sup>13</sup>C disturbances, mercury enrichments, and blooms of triserial guembelitriids and aberrant planktic foraminifera. The KPB, Dan-C2 and LC29n events, dated at 66.0, 65.8–65.7 and 65.47–65.41 Ma, respectively, have been recognized in all Tethyan and Atlantic localities, but only the KPB in the Pacific. Multiproxy analysis suggests that volcanic activity of the Deccan Traps did not have a relevant role in the aforementioned events, but contributed to environmental stress in the first 10 kyr of the Danian, and between ∼70 and 200 kyr after the KPB.</div></div>","PeriodicalId":55116,"journal":{"name":"Geobios","volume":"88 ","pages":"Pages 125-137"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examine the fossil assemblage recovered from the floor of the Baio cave (Zestoa, northern Iberia), which includes the remains of cold-adapted species. This site has yielded an assemblage that includes herbivores, carnivores and a small number of rodents. Our radiocarbon dating of the remains of a reindeer and a red deer yielded chronologies consistent with the Châtelperronian and Late Aurignacian occupations in the area, indicating a diachronic accumulation. Taphonomic observations suggest carnivores as being the main accumulation agents, with a minimal human contribution, along with the probable accumulation of some remains due to natural causes and/or the cave acting as a natural trap.

Nevertheless, the co-occurrence of diagnostic criteria for different anatomical elements (e.g., various teeth) enables specific identification.

The lack of expertise, however, hinders the systematic sampling and study of fish fossils in the country. We recommend developing a national program for paleoichthyological research and promoting paleontology by engaging researchers, government agencies, private collectors, and the general public.
