This bituminous schist is also remarkable as containing, in great abundance, the nearly perfect fossil remains of a large number of extinct species of fish. By The bituminous schist is succeeded by other beds more entirely argillaceous; and these are covered up by a compact limestone, which is the Zechstein, properly so called, and which rarely attains a thickness of more than twenty or thirty yards. The lower bed of the Zechstein is called Rauwaclcé, and consists of a hard but cellular magnesian limestone, abounding in long, irregular, and narrow cavities, which are most numerous when the bed attains a considerable thickness, but are almost obliterated in the thinner and more compact portions. To the Rauwacké succeeds a fetid limestone called Stin/cstein, which is a compact or granulated rock, of a blackish-brown or greenish colour, and extremely bituminous, giving out an offensive odour when struck or rubbed. Towards the upper part the bed is marly, and passes into a greyish, bluish, or greenish clay, well known under the name of lettm, and this often contains rolled fragments of dolomite and crystals of gypsum. In the zechstein and the beds associated with it, there are found occasionally several minerals, and, amongst the rest, white crystallized carbonate of lime, crystallized sulphate of lime or gypsum, quartz, and mica.
