Early Cretaceous ammonites from the Butkov Quarry (Manin Unit, Central Western Carpathians, Slovakia)

Vol. 60, no. 3

393-415

The taxonomic and stratigraphic study of rich ammonite material from the Lower Cretaceous deposits of the Butkov Quarry, near Ladce (ManIn Unit, Slovak Central Carpathians) is presented. More than 55 ammonite species are recognised and twenty-one biostratigraphically significant ammonite species are described, with one species, Sarasinella subdensicostata, described as new. The recognised taxa document an interval from the Upper Valanginian through to the Lower Hauterivian. The ammonite assemblage represents the Mediterranean bioprovince, with only a single species, Dichotomites evolutus, from the Boreal bioprovince.a new ammonite zone, the Teschenites flucticulus Zone, is proposed for the basal Hauterivian in the Western Carpathians.

A remarkable assemblage of Early Barremian ammonites in the Central Western Carpathians (Butkov Quarry, Slovakia)

A remarkable fossiliferous horizon dominated by ammonites has been recorded in Lower Barremian clayey limestones of the Butkov Quarry in the Slovak Central Carpathians. The rich ammonite assemblage yielded 16 genera and 21 species. The 15 species are described in detail; four of these are new. Numerous barremitids are accompanied by biostratigraphically significant pulchelliids, some heteromorphs and particularly by representatives of the family Holcodiscidae. The composition of the ammonite assemblage, which contains only taxa belonging to the Mediterranean faunal province, is characteristic of the Early Barremian Kotetishvilia compressissima ammonite Zone.
