Rønne Formation (Denmark) |
The Rønne Formation is a geologic formation on the island on Bornholm, Denmark. It is of middle Hettangian to early Pliensbachian age. Vertebrate fossils have been uncovered from this formation. During the Early Jurassic, on what is now the Bornholm region was transitional between continental and marine settings with tidal influence.[1] There was a lower delta plain, with lagoons and intertidal swamps.[2] The formation is correlated with the lower Rya Formation and the upper Höganäs Formation of Skåne, Sweden.[3]
Fossil content[]
The Rønne Formation has provided many fossil flora.[3]
