Stanowisko mamuta – Mammuthus primigenius (Blumenbach, 1799) w górnym plejstocenie Kopalni Węgla Brunatnego Bełchatów

The fossil remains of juvenile woolly mammoth (Mammuthus primigenius) from Pleistocene deposits of the Be³chatów coal mine are described. Precise measurements of the excavated bones allowed for approximate reconstruction of the specimen, which turned out to be in the estimated age of 10 years. Serial samples for isotope analysis of carbon and oxygen were taken from a tooth, and the isotope record has revealed a probable change of diet due to switching from milk-based to plant-based food.

Rhaetian/Hettangian palynomorphs of the Tatra Mountains (West Carpathians)

The uppermost Triassic and the lowermost Jurassic clastic-carbonate strata of the Sub-Tatric (Kriżna) unit of the Polish Tatra Mountains yield an important assemblage of microfossils - mostly foraminifers and also palynomorphs. The three representative Triassic/Jurassic boundary sections of the Kriżna unit (Lejowa Valley, Strążyska Valley and Mt. Mały Kopieniec) have been studied and sampled in order to establish a stratigraphical succession of microfossils. The palynomorph assemblage (spores, pollen grains and dinoflagellate cysts) were found in the transitional beds of the Fatra Formation (Rhaetian) and the basal clastics of the Kopieniec Formation [Hettangian-Sinemurian(?)] - Fig. 1. The assemblage contains 58 spore and pollen species and is dominated by pteridophyte spores (Dictyoniaceae and Matoniaceae). The biostratigraphically significant taxa: Concavisporites, Dictyophyllidites and Leptolepidites, indicate Rhaetian/Hettangian time interval (Fig. 1) - see Zavattieri, Batten (1996). The facies development and floral and faunal assemblages of the Triassic/Jurassic boundary sequence in the Kriżna unit are characteristic for the shallow-marine sedimentary environment (shoreface-offshore). The data presented support the earlier views (Goetel 1917; Gaździcki 2003) that the environmental conditions prevailing in the Tethys realm were quite similar to those in the epicontinental basin of the northwestern Europe during the Early Liassic times.
