Trylobity w eratykach wapieni beyrichiowych znalezionych u podnóża klifu orłowskiego w Gdyni (północna Polska)

Abstract

ported there by ice sheets from Scandinavia and some Baltic regions can be found. Sedimentary rocks, important to palaeontological studies, contain numerous fossils and, among others, arthropods. One of the most common rock types here is beyrichian limestone. Its fossil content allows us to recognize many varieties, such as Calymene limestone, Nucula limestone, Elevatus limestone and others. The present study concentrated mainly on trilobites found in these rocks and belonging to two genera: Calymene and Acaste.
