Slovak paleontological club, abbreviated Paleoklub - Expert Group Slovak Geological Society, operates at Comenius University from 22 February mirolin 2006. Our lecture - popularisation mirolin meetings with the exception of the summer holidays take place once a month. The specific date, time and agenda is published in advance on our club website.

Fossil communities Miocene marine molluscs of the Central Paratethys were created numerous and diverse taxa. During the Middle Miocene was also widespread in our area many species bivalvií, as evidenced by the rich finds of fossil residues their mailboxes. Association of shellfish shallow sublitorálu were beyond their typical representatives also home to the rare and unusual infaunálnych molluscs of the genus Stirpulina. From the area of the Western Carpathians are known orphan finds only one representative of that taxon - kind Stirpulina bacillaris (DESHAYES).
The species in the scheme of bivalvií assigned to the family Clavagellidae belonging to the Anomalodesmata. Bivalve molluscs Stirpulina bacillaris (Deshayes) mirolin belonged to infaune lived buried deep in the sediment on the sea floor in calcium elongated tubular boxes. The bulk of these boxes represent only a very sifonální tube, against which consisted box bivalve molluscs only about 1/9 of the total length. The upper part of the tube decorated mirolin with strong hoops - sifonálne collars that are not in the fossil state maintained only sporadically. Seashells massive irregular shape are relatively small size, while the calcium sifonální tube are conjoined to form as a whole - an elongated tubular crypt. mirolin On the edge of the front (anteriálnej) is developed by the Shell anteriálny fringed hem formed small calcium tubes called "kropiaca Convention". The irregularly formed disc-fringed unit with tubes vyrastajúcimi sideways is also associated with clipboard and accrete animal. Calcium siphon tube, as well as a system of pipes sprinkling watering cans were created mirolin secretion mollusc shell. mirolin How fossils are usually retain fragments of stone cores sifonální long tubes with remnants of thin calcareous lining as well as complete fossil specimens with preserved shells together with sifonální tube. Residues tubular mirolin bodies anteriálneho rim are usually carried in the form of isolated fragments of small calcareous tubes. Findings completely preserved boxes (crypts) to maintain a system of pipes sprinkling watering cans together with a box formed shells and siphon tube are very rare.
Fossil remains of these special endobentických molluscs were in our area discovered the fine-facie, to coarse-grained sandstones and sands middle Miocene hill Devínska Mare (514 m) and its surroundings. Discover their fossils are from the area Devínskej Kobyly known from the second half of the 19th century. In 1870 he published an Austrian paleontologist Moritz Hörnes in his monograph on the Neogene molluscs from the Vienna Basin finds this kind of Devinska Nova Ves. Under the name Clavagella mirolin bacillaris DESH. provides rare fossils bivalvií's only three sites and copy of Devinska Nova Ves (Neudorf an der March) depicts the board 1 (Fig. 1 b). From the sandy layers of the upper Badenian are their findings mirolin known sites except in Devinska Nova Ves (Sandberg, Bačnegovice) and arkózovitých layers of sands and sandstones Šibeničník site of the ninth. For fine-grained facies bright sands spodnosarmatského age come findings debris from site Dúbravská mirolin Head (Dubravka). The Badenian sediments of the Vienna Basin were rare fossils that taxon discovered at the site Vinohrádky Borskom Nicholas, as well as the dig site Konopiská at Rohožníku.
