Corals of the Štramberk-type limestones from Poland: Taxonomic and palaeoecological aspects
The paper provides new data and the summary of the previous studies on the taxonomy and palaeoecology of corals from the Štramberk-type limestones, occurring as pebbles to boulders (so-called exotics) in the flysch sucessions of the Polish Outer Carpathians. At least 80 species (53 genera) are known from these limestones. Less abundant and less diversified than corals of the Štramberk Limestone from Moravia, but they still represent one of the most species-rich assemblage of the latest Jurassic–earliest Cretaceous age (mostly Tithonian). Uniqueness of these coral faunas, especially in Czech Republic, is an unusual proliferation of the suborder Pachythecaliina (order Hexanthiniaria). 22 species and 14 genera occur in the Štramberk-type limestones in Poland. Corals, many with phaceloid growth form, are commonly associated with microbialites and microencrusters, which are important reef framework contributors. Macrobiota and microencrusters (some typical of the Tethyan Realm) suggest oligotrophic or mildly mesotrophic environments. Four scleractinian species are described, representing the poorly known genera Bilaterocoenia, Thecomeandra and Misistella.
