چکیده
Over three thousand specimens representing the superfamily Trochoidea Rafinesque, 1815 [Trochidae and Calliostomatidae Thiele, 1924 (1847)] from upper Upper Badenian = Kosovian lower Serravallian (middle Miocene) marine deposits of Ukraine, housed in collections Polish Academy Sciences Museum Earth Warsaw (MZ), are studied herein. The abundant material has allowed for investigations intraspecific variation revision earlier determinations. As a result, 21 species belonging to 5 genera have been identified, described illustrated, which one is new [Clanculus (Clanculopsis) krachi sp. nov.] left open nomenclature. Granulifera O.

A new and precisely defined chronometric subdivision of the Badenian (Middle Miocene, regional stage of Central Paratethys) is proposed. This uses global events, mainly geomagnetic polarity reversals as correlated chronometric boundaries, supported by climatic and sea-level changes in addition to isotope events and biostratigraphic data. The Karpatian/ Badenian boundary lies at 16.303 Ma, at th...

In situ preservation of mud shrimps of the family Callianassidae (Decapoda: Axiidea) has rarely been noted in the fossil record. The present contribution reports body fossils of four members of the family (“Callianassa” almerai, “C.” pseudorakosensis, “C.” sp. 1 and “C.” sp. 2) which are apparently preserved within their burrows, all from middle Miocene deposits of Austria, Slovakia and Hungary...

A total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the Miocene deposits of Khavich section, south of Sirjan, Kerman. Gastropods assemblage in Khavich area indicates deposition in shallow, warm ramp-type carbonate platform. The Miocene and even Oligocene gastropod assemblages, relatively similar to Khavich section, reported from the othe...
