Neptunidraco ammoniticus, risalente al Bajociano-Bathoniano, Giurassico Medio, esemplare di Metriorinchide dalle cave di Ambrogio Veronese. Coll. Museo di geologia Giovanni Capellini, visitato in occasione del Wikiraduno Bologna giugno 2023.
White bioclastic Upper Bajocian limestone from the Sabouret quarry in Saint-Martial-de-Valette, Dordogne, France. The weathered surface reveals the bioclastic nature (and therefore high energy deposition) of the limestone with all kinds of broken debris, tiny oolites and some urchin spines.

An atypical (without intertidal and supratidal environment) carbonate platform settles down along the margin. Shallow water oolithes and oncoids are deposited in a narrow zone between a basin with Cancellophycus to the north and a marine/swampy plain with abundants mollusc fauna. However the Mytilus formation, rich in bathonian and callovian foraminifera (Septfontaine, 1984 etc.), develop thick limestone beds tenth of meter above, wrongly attributed to the upper Jurassic. See discussion in Septfontaine (1984).

Figure 36: Artist’s interpretation of the early Albian, volcaniclastic, floodplain palaeoenvironment within the Australian-Antarctic rift graben, in the region of Eric the Red West. Scene depicting two individuals of Diluvicursor pickeringi on the cutbank of a high-energy meandering river, regional floral components and distant rift margin uplands. Floral components potentially included forest trees of Araucariaceae (Agathis and Araucaria), Podocarpaceae and Cupressaceae and lower story/ground cover plants, including pteridophytes (ferns, including equisetaleans), hepatics, lycopods, cycadophytes, bennettitaleans, seed-bearing fern- or cycad-like taeniopterids and early Australian angiosperms.
