Abstract

AbstractIn this paper we review five cancellariid assemblages from the Hungarian part of the Pannonian Basin (Börzsöny, Bakony, and Mecsek Mts regions) which yielded 26 species. Ten species are recorded for the first time in Hungary. One species, Scalptia nemethi n. sp. is described as new. A revision of the Hungarian museum collections and historical Hungarian literature is also provided. Sveltia salbriacensis Peyrot 1928 is considered a junior subjective synonym of Petitina inermis (Pusch 1837).

Highlights

The aim of this paper is to review the early Badenian distribution of the family Cancellariidae in the Hungarian part of the Pannonian Basin (Central Paratethys) by investigation of five recently collected mollusk assemblages (B€orzs€ony Mts: Letkes, Bakony Mts: Band, and Devecser, Mecsek Mts: Mecsekp€ol€oske and Tekeres, Fig. 1)
Twenty-six cancellariid species are recorded from five early Badenian (Middle Miocene) mollusk assemblages in the Hungarian part of the Pannonian Basin
Based on the comprehensive revision of Harzhauser and Landau (2012) and the gastropod collection of the HNHM, the highest diversity can be documented in the Faget Basin (SW Romania) at Costeiu de Sus with 22 species, while 21 species are known from the mollusk assemblages of Grund (North Alpine Foreland Basin), and in the Vienna Basin (Austria) at Gainfarn and Steinebrunn

Summary

Introduction

The aim of this paper is to review the early Badenian (early Middle Miocene) distribution of the family Cancellariidae in the Hungarian part of the Pannonian Basin (Central Paratethys) by investigation of five recently collected mollusk assemblages (B€orzs€ony Mts: Letkes, Bakony Mts: Band, and Devecser, Mecsek Mts: Mecsekp€ol€oske and Tekeres, Fig. 1). Photos of the cancellariid assemblage from Letkes in the Senckenberg Forschungsinstitut, Frankfurt am Main (SFI) were studied; these specimens were collected by Helmut Krock, late German fossil collector. As a result of the research 26 species are described and illustrated in this paper; 21 species are recorded from Letkes, seven from Band, five from Devecser and Tekeres, and two from Mecsekp€ol€oske. Bonellitia austriaca (Hoernes and Auinger), Contortia callosa (H€ornes), Contortia tortoniana (Sacco), Merica obsoleta (H€ornes), Ovilia excassidea (Sacco), Perplicaria mioquadrata (Sacco), Scalptia dertoparva (Sacco), Scalptia polonica (Pusch), Trigonostoma exampullaceum (Sacco) and Tritonoharpa mariechristinae Lesport, Cluzaud and Verhecken are recorded for the first time in Hungary; a new species, Scalptia nemethi n. sp., is designated
