Samples for datings were taken in the railway construction (2TDK) near village of Divača, Classical Karst on October 12, 2021: (1) vertebrate bones in cave 2TDK – 002 at the profile P18, cave entrance appeared during the construction operations on cleaned karst surface in a wall of karst depression. Samples of mammal bones and gastropods were collected in situ on cave bottom, and (2) pieces of speleothems occurring in non in situ position on artificially planated surface near the cave opening were collected. U-series: no numerical date was obtained as geochemistry of sample indicate open system, probably due to recrystallization of sample in soil cover. Paleomagnetism: The transition of N- and R-polarized samples cannot be identified more precisely as U-series radiometric dating yielded no numerical results. The transition easily can represent Brunhes/Matuyama boundary (at 773 ka) as well as any of older such transitions (e. g., base of Jaramillo, base of Olduvai). In any case the speleothem grew in a closed cave space with roof, probably as flowstone (inclusion of red soils above the base) and later as baldachin on eroded allogenic fill of the paleocave. Vertebrate paleontology: bone remains of small and larger vertebrates represent subrecent to Holocene species. Sorex alpinus represents the species quite rare in fossil record, but recetly limited to variegated woodland habitats with high surface humidity. A chamois Rupicapra rupicapra represents a resident species present in Slovenia throughout all stages of a glacial cycle, recently restricted to mountain habitats.

Zpráva je volně šiřitelná od roku 2015. Anotace: Detailed paleomagnetic analysis of sedimentary profile at Teichkluft showed that sediments are characterized by varying magnetic susceptibilities and NRM with increasing tendency of anisotropy parameter with increase of susceptibility. The component analysis identified 2 short R polarity intervals (0.41 m; 2.19–2.26 m) within samples with the N polarity. Rock magnetic and AMS measurements indicated mostly the presence of oblate, low coercivity magnetic fraction, presumably magnetite. However, the R polarity interval (2.19–2.26 m) revealed also other, higher coercivity fraction (maybe due to hematite/goethite content). The identity of this fraction is still unknown. The R polarity interval in 0.41 m represents a geomagnetic excursion without any doubt. The sedimentary profile with the R polarity interval in 0.41 m must be older than 162.7 ± 3.9 ka old topmost speleothem. The paleomagnetic directions (D, I) are very close to the present magnetic field. Therefore we assume deposition of studied sediments within the Brunhes chron (<780 Ka) and the excursion may be correlated with Jamaica-Pringle Falls (205–215 ka) or Calabrian Ridge 1 excursions (315–325 ka; Langereis et al. 1997). Other Th/U date was obtained at the tourist trail opposite to Teichkluft entrance (ca 495 ka +67/-41 ka) in an altitude corresponding to the top of the Teichkluft profile. This might indicate that the Teichkluft was completely or nearly completely filled twice (before 163 and ca 495 ka) and once completely excavated (between ca 205/325 and ca 495 ka). The fragments of cuticle of ring-like shape at the level of 2.30 m belongs to attemsiid millipedes. The probability that fragments represent Polyphematia moniliformis (Latzel, 1884; Diplopoda: Chordeumatida: Attemsiidae) known in the cave is high. It is supposed they are Tertiary relict (Mock and Tajovský 2008). It is not detected, if fragments represent relics of recent/subrecent animal
