Ciechocinek Formation
The Ciechocinek Formation, formerly known in Germany as the Green Series (German: "Grüne Serie") is a Jurassic (lower Toarcian) geologic formation that extends across the Baltic coast, from Grimmen, Germany, to Nida, Lithuania, with its major sequence on Poland and a few boreholes on Kaliningrad. Dinosaur remains are among the fossils that have been recovered from the formation, not yet been allocated to a specific genus. The layers assigned to the formation are a group of sediments that differ from the those of the Posidonia Shale and other Toarcian formations of Europe. Most of the sediments of the Polish realm come from deltaic, fluvial and marine deposits. In the Polish realm there is also an abundance of siderite, attributed to mixed saline and marine action, with the rounding off of some due to transport by freshwater or sea currents. Its main equivalents are the Posidonia Shale, upper part of the Rydeback Member, Rya Formation (Southern Sweden), the Fjerritslev Formation (Danish Basin), the Bagå Formation (Bornholm) or the Lava Formation (Lithuania). There are also coeval abandoned informal units in Poland: Gryfice Beds (Pomerania region), Lower Łysiec beds (Częstochowa region), or the "Estheria series".
