FORMATION OF NORTHERN GERMANY. 137 
numerous yellow undulating lines, and finally of a perfectly 
ochreous colour. Fossils are frequent in the large stone quarries 
on the northern declivity of the mountain, and among them 
occur— 
Hamites gigas. Thracia Phillipsi. 
Ammonites Decheni. ... elongata. 
Mya elongata. 
The most westerly occurrence of the “quader” is on the 
north of Recklinghausen in Westphalia. It here forms the 
Haard; and at Haltern the Annaberg, and the Hohemark. In 
the whole of this district it occurs sometimes as a whitish, but 
generally brownish or reddish, perfectly loose sand, sometimes 
200 feet in thickness, which encloses numerous nodules of brown 
ironstone and quartz, from the size of a fist to that of a foot, 
and frequently hollow in the interior; and it alternates with 
nearly horizontal layers, from 2 to 3 feet in thickness, of a com- 
pact sandstone very much fissured, frequently passing into a 
quartz rock. Fossils are not rare in this peculiar deposit, espe- 
cially Pecten muricatus, and P. quinguecostatus, Exogyra, Chama 
costata, Mytilus eduliformis, and Inoceramus mytildides var. 
Among these there are no characteristic species; and it is there- 
fore still possible that the whole of the deposit may be of a 
more recent age; it might perhaps likewise be considered as an 
equivalent of the upper white chalk. 
In Saxony we find the lower greensand in the immediate 
neighbourhood of Dresden, on the left bank of the Elbe at Coste- 
baude, Bannewitz, Welschhufe, Rippchen and Golberoda; but 
it is here difficult to determine the upper limit of the formation. 
At Bannewitz, for instance, the following succession of strata 
appears in the Burgck stone quarries:
