Bedrock Age: Jurassic, *all periods
Description of primary interest:
The Late Jurassic (Lower to low-Upper Kimmeridgian) sequence of a carbonate platform of the Bahamian type developed widely across the area of Central Poland, and exposed at Małogoszcz Quarry, displays a variety of facies ranging from oolitic shoals and cross-bedded banks, intraoolitic shallow basins, to deeper offshore facies fluctuating into oyster coquinas (Actinostreon and/or Nanogyra shellbeds) of tempesite and/or storm shellbar origin. Ubiquitous fossils of various kinds, echinodermas in particular (echinoids Rhabdocidaris, Gymnocidaris, Holectypus; free-living crinoids Comatulina, stalked Apiocrinites; ophiuroids and starfish), as well as ammonites, non-ostreid bivalves, gastropods, brachiopods, isopods and lobsters make up a far-fame of the site. Easy insight into ancient oolitic banks and oyster shellbars.
