The K-Pg interval of the Seymour Island section was deposited in a deltaic/estuarine system with considerable sedimentary input from the erosion of a distant volcanic arc at the Antarctic Peninsula, combined with ash fallouts from explosive volcanic eruptions. The Maastrichtian interval represents the prodelta of a delta prograding in a marginal marine setting, whereas the Paleocene interval was deposited in more open, shallow marine conditions, following sea-level rise and shoal submergence above the K-Pg boundary. Dinocyst biostratigraphy indicates that in the studied section the K-Pg boundary is represented by a gentle erosive surface, 30 cm below a partially-indurated, marker sandstone bed. The dinoflagellate assemblages show quantitative changes across the boundary. Representatives of <i>Manumiella</i> group together with abundant <i>Palambages</i> dominate the assemblages in the lower part of the section, i. e. below the K-Pg boundary. There is an evident peak of <i>Fibrocysta/Ifecysta/Cordosphaeridium</i> just above the boundary. In the upper part of the section, <i>Senegalinium</i> reaches relatively high abundance together with <i>Impletosphaeridium clavus</i>. While relatively high concentrations of soil-derived organic matter inhibit the use of the TEX<SUB>86</SUB> paleothermometer to reconstruct sea surface temperatures, the MBT′/CBT paleothermometer indicates warm mean annual air temperatures for the latest Cretaceous (16.0–16.5 <sup>°</sup>C). These high temperatures, coinciding with the lowest abundance of the high-latitude pollen taxon <i>Nothofagidites</i>, may reflect the terminal Cretaceous Deccan Traps-warming pulse. Fluctuating temperatures followed in the early Paleocene, characterized by ~2 degrees drop in air temperatures, coincident with the maximum percentage of the high-latitude angiosperm <i>Nothofagidites</i> spp. and the cold-water dinocyst taxon <i>Impletosphaeridium clavus</i>. The recognition of ecological signals of disturbances and their relationship with short-term climatic and environmental changes, provides new insights related to the effect of the impact at the high-latitude K-Pg boundary of Antarctica.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A high-resolution record of environmental changes from a Cretaceous-Paleogene section of Seymour Island, Antarctica","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:32:08.535195","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sedimentology; Palynology; BiomarkersK-Pg; Paleotemperatures","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-05-17","DateCreate":"2020-09-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000552137900006","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.palaeo.2020.109844"},"refs":null,"anarec":{"AnaID":328458,"PubliDate":2020,"Pagination":"109844","XtraPublOfAnaID":null,"ISBN":null,"Volume":"555","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43483,"SerRR":"Palaeogeography, Palaeoclimatology, Palaeoecology.
