Early Paleogene events of the Alpine Tethys were considerably upgraded for the Western Carpathians. The Kršteňany KRS-3 core section provides high-resolution data from the Cretaceous-Paleogene (K/Pg) transition to Lutetian/Bartonian boundary. The Upper Cretaceous sequence started from terrestrial red-beds superposed by transgressive sediments with Abathomphalus mayaroensis. The K/Pg transition is inferred in a horizon with reworked Maastrichtian microfossils and earliest Danian species of Globigerinidae. Multiple redeposition with eugubina-rich clasts implies a storm erosion and resuspension of the post K/Pg sequence during P0 - Pα Zones (approx. 300 kyr). The early Danian microfauna was initially impoverished, later enriched by first praemuricids, and after the Latest Danian Event (LDE) diversified to angulate morozovellids, igorinids and fasciculiths. Paleocene bioevents and polarity chrons imply a radiation of planktic foraminifera during transgressive cycles in the late Danian (P1, C28n), Middle Selandian (P3b, C26r/n) and late Thanetian (P4c/P5, C25n/C24r), and vacant P/C zones either in regressive cycles or during unconformities in the early Danian (P1a/C28r), Danian/Selandian transition (P2/P3a, C27r/n) and middle Thanetian (P4b/C25r). The late Thanetian transgression (Th-2) led to replacement of Assilina-rich beds (SBZ 4) by Nummulites-bearing marls (SBZ 5) at the base of Ilerdian (= LFT). The Paleocene – Eocene transition is marked by Acarinina-rich marlstones with densely muricate species (Ac. acarinata) and excursion taxa (Ac. sibaiyaensis, D. araneus), which correspond to the Paleocene-Eocene Thermal Maximum (PETM). This horizon implies a warm-water productivity, eutrophication, humidity and upwelling activity (pteropods, diatoms). The hyperthermal conditions culminated at the beginning of the Early Eocene Climatic Optimum (EECO) with demise of morozovellids, intensification of hydrological cycles and enhanced continental input of siliciclastics, which progressed by accumulation of Ypresian nummulite banks and terminated by pelagic deposition with recovery of hispid morozovellids (E5 – E7 Zones, chron C23n - C22r). The lower Lutetian sequence reveals a post-EECO cooling by predominance of deep-dwelling habitats (subbotinids, turborotaliids, catapsydracids) and appearance of subtile morozovellids (M. gorrondatxensis), earliest globigerinathekids and another marker species of the E7 – E8 Zones (chron 22n - C21r). Late Lutetian warming (LLTM) is indicated by increased plankton productivity of mixed-layer habitats like strongly muricate species of anguloconical acarininids (Ac. topilensis, Ac. medizzai) and gracile species of morozovelloids (M. coronatus). The youngest part of the Kršteňany section belongs to the E11 Zone, indicating prior conditions of Middle Eocene Climatic Optimum (MECO) warming.

对于西喀尔巴阡山脉而言，阿尔卑斯特提斯山脉的早期古近纪事件大大升级。Kršteňany KRS-3 岩心剖面提供了从白垩纪-古近纪 (K/Pg) 过渡到 Lutetian/Bartonian 边界的高分辨率数据。上白垩统层序始于与Abathomphalus mayaroensis 的海侵沉积物叠加的陆地红层。K/Pg 转变是在重新加工的马斯特里赫特微化石和最早的丹宁类球虫科物种的地层中推断出来的。用eugubina多次再沉积富碎屑意味着在 P0 - Pα 区（约 300 kyr）期间，风暴侵蚀和后 K/Pg 序列的重新悬浮。大年早期的微型动物群最初是贫瘠的，后来被最初的 praemuricids 丰富，在最新的大年事件 (LDE) 之后多样化为有角的 morozovellids、igorinids 和 fasciculiths。古新世生物事件和极性年代意味着在晚达尼安 (P1, C28n)、中色兰阶 (P3b, C26r/n) 和晚塔尼阶 (P4c/P5, C25n/C24r) 和空置的 P/ C 带要么处于倒退旋回中，要么处于大尼阶早期（P1a/C28r）、大尼阶/塞兰阶过渡（P2/P3a、C27r/n）和中塔尼阶（P4b/C25r）的不整合面。Thanetian 晚期海侵 (Th-2) 导致富含 Assilina 的床 (SBZ 4) 被替换为Ilerdian (= LFT) 底部的含Nummulites泥灰岩 (SBZ 5)。古新世 - 始新世过渡的标志是富含 Acarinina 的泥灰岩，具有密集的鼠类（Ac. acarinata）和远足类群（Ac. sibaiyaensis, D. araneus)，对应于古新世-始新世热最大值 (PETM)。这个地平线意味着温水生产力、富营养化、湿度和上升流活动（翼足类动物、硅藻）。高温条件在早始新世气候最优 (EECO) 开始时达到顶峰，随着 morozovellids 的消亡、水文循环的加强和硅质碎屑的大陆输入增加，随着 Ypresian nummulite 银行的积累而发展，并以远洋沉积终止，伴随着硬毛状morozovellids 的恢复（E5 – E7 区域，chron C23n - C22r）。较低的 Lutetian 序列揭示了 EECO 后因深居栖息地（subbotinids、turborotaliids、catapsydracids）的优势和细纹 morozovellids ( M. gorrondatxensis ) 的出现而变冷)，最早的 globigerinathekids 和 E7 – E8 区的另一个标记物种 (chron 22n - C21r)。Lutetian 晚期变暖 (LLTM) 表现为混合层生境的浮游生物生产力增加，例如角锥螨类（Ac. topilensis、Ac. medizzai）的强粘虫种和 morozovelloids 的纤细种（M. coronatus）。Kršteňany 部分最年轻的部分属于 E11 带，表明中始新世气候最优 (MECO) 变暖的先决条件。
