OOLITES OF GERMANY. 



Inferior oolite. 

 Lias. ' 

 Keuper. 



Upper red and yellow 

 mar J. 



Muschel-kalk, want- 

 ing in England. 



Bunter sandstone. 

 Lower red sandstone. 



Rothe-todte-liegende. 

 Lowest red sandstone. 



C The inferior oolite of Wurtemberg, Bavaria, Hanover, 

 < and Westphalia, analogous to that found on the Yorkshire 

 f coast; it rests upon lias. 



Lias marl and gryphite limestone occur in the countries 

 named in the preceding section. 



A formation of purple, red, and green sandstone, and 

 marl of enormous thickness, reposing on muschel-kalk, 

 and surmounted by lias. Mr. Murchison believes that 

 the Keuper is the true representative of the English red 

 ^and green marls. 



More than 600 feet in thickness, contains remains of 

 the ichthyosaurus and plesiosaurus, the crocodile, and 

 1 turtle: the salt mines of Wurtemberg are in this forma- 

 ' tion. 



Analogous to the English lower red sandstone, with 

 magnesian limestone. 



The lowest red sandstone of Professor Sedgwick, like 

 the English sandstone: it rests on transition limestone or 

 coal measures. 



It is deserving notice, that many of the beds in the above section 

 not only contain the same fossils as those in the English series, but 

 also preserve the same mineral characters. Where this is the case, 

 we can arrive at satisfactory conclusions ; and such beds serve as a 

 key to the discovery of the true nature of the beds above and below 

 them, where the characters may be less clearly defined.
