Remake of the original picture of the Drzewica Formation. Terrestrial environment of the Pliensbachian-Toarcian boundary of Fennoscandinavia Inland environment of the Bornholm Coast, nearby the German realm of the Ciechocinek Formation. Includes Ciechocinek Formation (Lower Toarcian, Bones) and Drzwica Formation (Latest Pliensbachian, Footprints) Fauna Sorthat Formation environment, fluvial influenced mainland with Cheirolepidaceae and Bennetitales as dominant flora Dinosaurs are based on material found on various locations of Northern Germany, and Footprints of the underliying Drzewica Formation at the Holy Cross Mountains, connected with Bornholm at the time. Dinosaur Species appeared: Megalosauripus isp. Large Footprints (+65 cm) found on the Drzewica Formation. There is a dorsal vertebrae on the German Margin of the Ciechocinek Formation assigend to Megalosauria (Huene, 1966). Gravisauria spp. representing the Grimmen Sauropod reported on 2014, as a taxon related with Tazoudasaurus. Barapasaurus-like footprints are know from the Drzewica Formation. Coelophysoidea spp. based on coeval Anchisauripus tracks from the Holy Cross Mountains. Basal Ornithischan, related to Eocursor, based on a crouching trace (Gerard Dariusz Gierlinski, Martin G. Lockley, Grzegorz Niedźwiedzki:2009). Massospondylidae spp. based on Otozum-like tracks.
