Abstract
The Sinemurian ammonoids from the boulders in the Greek quarry (Salgir River basin, south-east of Simferopol city) are described. The assemblages are represented by Phylloceratidae (Phylloceras, Zetoceras and Partschiceras), Juraphyllitidae (Juraphyllites and Paradasyceras), Schlotheimiidae (Phricodoceras), Arietitidae (Coroniceras, Metophioceras, Arnioceras and Asteroceras), Oxynoticeratidae (Gleviceras), Echioceratidae (Plesechioceras, Orthechioceras, Echioceras and Paltechioceras), Eoderoceratidae (Eoderoceras), Epideroceratidae (Epideroceras) and, questionably, Coeloceratidae (?Tetraspidoceras). A new species Asteroceras dommerguesi sp. nov. is described. A sequence of biostratigraphic units was reconstructed and correlated with known biostratigraphic units (zones, subzones and biohorizons) of the Mediterranean area. The ammonite assemblages were found to be close to those of the northern Tethyan margin (Pontic and Austroalpine subprovinces).
