In paper a fragment of mammal tooth from Oligocene beds of Senovo colliery is discussed. Available is the distal half of third left molar from maxilla of an anthracotherian of species Anthracotherium ...magnum Cuvier, 1822 that is kept in geologic collection of the elementary school at Senovo. In Slovenia anthracotherian teeth were found in beds of the same age at Zagorje, Trbovlje, Hrastnik and Laško. All anthracotherian remains in Slovenia were found in coal deposits.
The article deals with the sites of Miocene sedimentary rocks in north-eastern Slovenia. Due to dense vegetation cover and consequently rare rock outcrops mostly abandoned quarries were elaborated. ...According to evaluation criteria defined by Nature Conservation Act and Decree on the categories of valuable natural features, out of 28 examined locations 6 were selected as important from the nature conservation point of view. These sites contain mainly the fossilferous lithothamnian limestone and they are proposed to be listed as valuable geological natural features. The quarries Osek – oolite limestone and sandstone site and Zgornji Duplek 1 –lithothamnian limestone siteare proposed as geological natural values of national importance. The lithothamnian rocks used to be importantbuilding stone. Nowadays we find it in some of important cultural monuments like castles, churches and other cultural monuments. In this respect some of the sites of Miocene sedimentary rocks have significant cultural value as well.
Oligocene and Miocene beds in Kozjansko, SW part of the Parathetys region, were developed in the time span ranging from Kiscellian to Pannonian, with two emersion phases – the first in Ottnangian, ...Karpatian and partially Badenian, and the second in Badenian and Sarmatian. Kiscellian sedimentation started with basal conglomerate, which was followed by sand, marl with coal seams, and marly clay (sivica). Clastic sedimentation was accompanied by volcanic activity that produced andesites, dacites, and andesitic,dacitic and rhyolitic tuffs. Egerian deposits include sands, sandstones, siltstones, claystones,marls and tuffs (the Govce beds). Eggenburgian deposits are characterised by quartztoze and gluconitic sandstones (the Macelj sandstones) and conglomerates. Badenian deposits are among the most widespread in occurrence and the most diverse in development. Theyare known as the Laško beds. Marls and siltstones predominate over massive lithothamnian limestone, calcareous-quartztoze conglomerate and biocalcarenite. They contain marine fauna. Badenian tuffs have been newly discovered on the territory of Kozjansko. InSarmatian, the environment changed from marine to brakish and freshwater. Transgressively deposited conglomerate is overlain by sand, marl, sandstone and scarce beds of marly limestone. Clastic sedimentation continued in the Pannonian time, too.
Rhodolith beds are the basal transgressive unit of the several hundred metres thick Badenian succession, and are a pecuharity of the Kozjansko area.Rhodoids are mainly spherical having up to 15 cm in ...diameter. They are built of Lithothamnium corallinacean algae with crusty and branching texture, frequently intergrown with bryozoans. The rhodoid nuclei commonly consist of pebbles of Palaeozoic clastic rocks (quartz, phyllites), Triassic carbonates and Oligocene tuffs.The rhodolith occasionally passes into a rhodolithic conglomerate. Sparsely rhodoids of somewhat smaller dimensions also occur in lithothamnium limestone (biocalcarenite). Rhodolith was formed in nearshore, well agitated areas of the Tertiary Kozjansko basin.
