Salt occurs in the Muschelkalk at Friedrichshall and some other localities in Wurttemberg and Thuringia; and in the Bunter at Schoningen near Brunswick.
The Bunter sandstones of the Vosges have afforded several species of Lower Triassic plants; these include the Equisetaceous genus Schizoneura - a member also of the Glossopteris flora - bipinnate fern fronds referred to the genus Anomopteris, another fern, described originally as Neuropteris grandifolia, which agrees very closely with a southern hemisphere type (Neuropteridium validum, fig.
These two instances - the Tongking beds of Rhaetic age and the Bunter sandstones of 'the Vosges - afford evidence of a northern extension of Glossopteris types and their association with European species.
Flanking the hills between Ashbourne and Quarndon are red beds of Bunter marl, sandstone and conglomerate; they also appear at Morley, east of the Derwent, and again round the small southern coalfield.
Next in importance to the Chalk formations as a source of underground water supply comes the Trias or New Red Sandstone, consisting in Great Britain of two main divisions, the Keuper above and the Bunter below.
