. Elements of geology. Geology. PART II. CHAPTER XIX. 241 Fossils of the Magtiesian Limestone. When we consider the fossils of the Magnesian Limestone in England, or corresponding Zechstein in Germany, we find that they approach much nearer in their character to the organic remains of the older carboniferous group than to those of the Upper New Red. Thus, for example, the two genera of shells, Producta and Spirifer, of the family Brachiopoda, are common Fig. 240. Fig. Producta calva, Sow. Spirifer ujtdulatus. Sow. (Lept(Bna,J)a]m^^.)

There are certain fish also found both in England and Germany, in the Lower New Red System, which occur in the carboniferous strata, but in no formation higher in the series than the Magnesian limestone, not even in the Muschelkalk.
