Illustration of an ideal landscape of the Upper Oolite, a rock formation of the Jurassic Period found in England and Europe, from Louis Figuier's The World Before the Deluge, 1867 American edition. Vegetation includes Sphenophyllum tree-ferns, Pandanus trees, cycad-like Zamites, and many conifers. Aloft in the air floats Archaeopteryx, the bird of Solenhofen. On the ground are Rhamphorhynchus (leaving tracks), Crocodileinus, and various marine invertebrates (Asteria, Comatula, Hemicidaris, Pteroceras). A coral atoll rises offshore.
