Gastropods of the Lower Jurassic Hierlatz Limestone Formation, part 2. Some new archaic type slit-bearing components from the fauna of the Hierlatz Alpe (Hallstatt, Austria) and the Bakony Mts (Hungary)

Abstract

-Th is paper presents the taxonomic classifi cation of gastropod specimens mainly from yet unpublished parts of collections of the Early Jurassic Hierlatz Limestone fauna. Th e discussed species most probably belong to such higher rank taxa that have been formerly thought to become extinct during the Late Triassic crisis and represent groups typical of Palaeozoic to Triassic times. Th e new taxa are: Wortheniopsis rakusi n. sp., Wortheniopsis bakonyensis n. sp., Foveolaria n. gen., Foveolaria bicarinata n. sp., Foveolaria conoidea n. sp., Foveolaria globosa n. sp., Foveolaria suemegensis n. sp., Foveolaria kocsisi n. sp. and Foveolaria sp. (?Pithodeidae), and Cyclostomaria praemonarii n. sp. (Gosseletinidae). With 40 fi gures.

Middle Triassic (Anisian, Bithynian) gastropods from North Dobrogea (Romania) and their significance for gastropod recovery from the end‐Permian mass extinction event

“…Szabó () questionably placed Wortheniopsis in the family Pithodeidae which has a late Palaeozoic type genus. Mazaev () synonymized Plethospiridae and Pithodeinae (Ordovician type genus) but this is not beyond doubt according to Bouchet et al .…”

Gastropods of the Lower Jurassic Hierlatz Limestone Formation, part 3. New pleurotomarioideans from the fauna of Hierlatz Alpe (Hallstatt, Austria)

“…Actually the taxonomical status of this "mega-species" has not yet been arranged satisfactorily (see also Monari & Gatto 2013, p. 771). Th e situation is similar to the case of "Pleurotomaria foveolata" (Szabó 2017): is Pleurotomaria debuchi a single species or a group of unsatisfactorily known species, and does this/these species belong to Pleurotomaria at all? In the Hierlatz Alpe fauna, some "varieties" of P. debuchi occur (Stoliczka 1861, Szabó 2008, 2009 but all are diff erent from P.?…”

“…Some specimens are from subsequent, mostly anonymous collectors. Th e characterization of the material and the locality, provided in the previous parts of the series on the Hierlatz Limestone gastropods (Szabó 2009(Szabó , 2017, concern also the objects of this paper.…”

Early Jurassic (Sinemurian) gastropods from the Lusitanian Basin (west of Portugal)

“…In the last few years, gastropod faunas from other Lower Jurassic European basins have been published, mainly in Germany (Gründel, 2003(Gründel, , 2007a(Gründel, , 2007b(Gründel, , 2010Nützel & Gründel, 2015;Schubert et al, 2008), Austria-Hungary (Szabó, 2008a(Szabó, , 2016, England (Gründel et al, 2011;Todd & Munt, 2010) and Italy (Conti et al, 2004;Fischer et al, 2002;Gatto & Monari, 2010;Szabo et al, 2019). Researches about faunas from France (Gatto et al, 2015), Luxembourg (Monari et al, 2011) and Turkey (Okan & Hosgör, 2007), and other non-European countries, such as Argentina (Damborenea & Ferrari, 2008;Ferrari, 2009Ferrari, , 2013Ferrari, , 2014Ferrari et al, 2014) have also been published.…”
