Plattenkalk are stacks of laterally continuous layers that cleave into flat blocks or thin sheets. A much more general term for this type of lithology is platy, but this term implies beds ranging from 1 to 30 cm, and the Solnhofen Limestone can contain layers much thinner than that. This limestone which is strictly the plattenkalk, was deposited in the Jurassic, more specifically in the Early Tithonian .

  As mentioned in the previous page, the Romans used this limestone for carvings and drawings. This is a carving by Doman Herring titled 'The judgement of Paris', in 1508. Because of the exceptional sorting (95 - 98% calcium carbonate) and size of the limestone grains as well as its continuity it makes the limestone excellent for carving (modified from Barthel et. al., 1990).
