Miocene land snails from Belchatöw (Central Poland), III: Carychiinae (Gastropoda; Pulmonata: Ellobiidae)

KurzfassungIn den Kalkstein-Zwischenlagen einer Lignit-Sequenz des Braunkohlen-Tagebaus Belchatöw werden neun Arten der GattungCarychium und eine Art der GattungCarychiopsis beschrieben. Drei stratigraphisch verschiedene Schichten (Beł-A, Beł-B and Beł-C), in denen Überreste von Landschnecken vorkommen, werden den biostratigraphischen Zonen MN 4 - MN 9 zugeordnet. Als neue Arten werdenCarychiopsis prisyazhnyuki, Carychium achimszulci undC. surai beschrieben.AbstractNine species ofCarychium and one species ofCarychiopsis are described from calcareous intercalations within lignite sequences in the brown coal mine of Bełchatów. Three stratigraphically different levels (Beł-A, Beł-B and Beł-C) containing land snail remains have been referred to the biostratigraphic zones MN 4 — MN 9. Three new species are reported:Carychiopsis prisyazhnyuki, Carychium achimszulci andC. surai.

Late Paleozoic Continental Gastropods from Poland: Systematic, Evolutionary and Paleoecological Approach

Abstract Two taxa of the Late Carboniferous and four species of the Early Permian terrestrial snails have been found in the Late Paleozoic continental molasse sediments of the Upper Silesian-Cracow Upland (Southern Poland). Discovery of Anthracopupa ohioensis and Protodiscus priscus indicates that, besides in North America, they occurred also in the European part of the Pangea supercontinent. According to the general sedimentary facies context and the accompanying floral and faunal assemblages, the gastropods lived in swamp environments, including a topogenous fen.

Miocene land snails from Belchatow (Central Poland), I. Cyclophoridae, Pomatiasidae (Gastropoda Prosobranchia)

KurzfassungDrei Kalksteinhorizonte einer Lignit-Sequenz der Braunkohlengrube Belchatöw (51°15′’N, 19°202032;’E) enthalten eine reiche Landschneckenfauna von über 40 Arten. Das radiometrische Alter dieser Faunen (Beł-A und Beł-B) liegt zwischen 18.1 ± 1.7 Mio und 16.5 ± 1.3 Mio Jahren, der Beł-C Horizont befindet sich aber unter den datierten Tuffhorizonten und scheint älter zu sein. Fünf Arten der Cyclophoridae und Pomatiasidae werden beschrieben, darunter die neuen ArtenProcyclotella?glazeki n. sp. undCaspicyclotus belchatoviensis n. sp.AbstractThree calcareous intercalations within lignite sequences in the open-cast mine Belchatów (51°15’N, 19°20’E) yield rich land snail faunas of over 40 species. Fission-track ages of these faunas (Beł-A and Bel-B) range from 18.1 ± 1.7 Ma to 16.5 ± 1.3 Ma, though the Beł-C level lies below the dated tuffitic intercalations and seems to be older. Five species of Cyclophoridae and Pomatiasidae are described including two new species:Procydotella?glazeki n. sp. andCaspicyclotus belchatoviensis n. sp.

Miocene land snails from Belchatów (Central Poland). II: Aciculidae (Gastropoda Prosobranchia)

KurzfassungIn den Kalkstein-Zwischenlagen einer Lignit-Folge des Braunkohlen-Tagebaus Belchatów wurden fünf Arten der Familie Aciculidae gefunden, die in diesem Aufsatz besprochen werden. Zwei dieser Arten,Acicula schlickumi (Schutt 1967) undRenea pretiosa (Andreae 1904) waren bisher nur in wenigen unvollständigen Gehäusen bekannt. Als neue Art wirdAcicula crassistoma n. sp. beschrieben.AbstractThe paper reports five species of Aciculidae from calcareous intercalations within lignite units of the opencast brown coal mine in Belchatów. Two of them,Acicula schlickumi (Schütt 1967) andRenea pretiosa (Andreae 1904) were only poorly known on the basis of some incomplete shells, whileAcicula crassistoma is described as a new species.

Professor Andrzej Wiktor - on his 80th birthday

This year we celebrated the eigthieth birthday of our friend, colleague, teacher and boss, Professor Andrzej Wiktor (Fig. 1). This issue of the Folia is dedicated to him. We all wish him many happy returns and further malacological success. Andrzej Hubert Wiktor was born the 4th of February 1931 in Nowa Wieœ near Rzeszów. The son of Józef and Maria neé £oœ, he was the youngest of four children. He had two brothers: Józef (1923–2000, ichthyologist, professor at Gdañsk University) and Stanis3aw (1926–2007, ship-building engineer), and a sister (Krystyna Wiktor-Jacobson, artist). His father was a landowner, and the family stayed in Nowa Wieœ almost till the end of World War II. Andrzej went to primary school in the nearby town of Czudec near Rzeszów and finished it during the war. In 1944 the family moved to Gorlice and after the war – to Sopot. This is why Andrzej started his secondary school education in Gorlice just after the war, but continued in Gorlice and Sopot, and then in Gdynia-Or3owo where he passed his school-leaving exams in 1949. In the same year he started studying biology at Poznañ University. At that time in Poznañ it was only possible to get bachelor’s degree in biology. After obtaining his bachelor’s degree, thanks to his good results, Andrzej was offered one of the two positions to continue his studies in zoology at one of the two universities in Poland which then offered master’s courses (Wroc3aw and Vol. 19(4): 193–200
