This group contains eleven or more series of I 

 strata, and is characterized by its Ammonites ; 

 some of which are said to be as large as a \ 

 coach-wheel, while others are of the size of ] 

 a sixpence ; it does not cover a large area, | 

 but has many fossils, such as Reptilia, (some ! 

 of which have been found eighteen or more ! 

 feet in length, Icthyosaurus, Plesiosaurus, ! 

 Amblyrhynchus, <&c.) Bones of many kinds ' 

 of Fish, as the Chimaera, Insects, Zoophytes, 

 Radiata, Conchifera, Mollusca.

Coal Measures. 



1. Coal. 



2. Millstone Grit. 



3. Mountain or Carboniferous 



Limestone. 



This section does not differ much from the rest j 

 of the Oolite, but in not containing the Oolite 

 mineral called Roestone, and being the low- 

 est of the group. 



The fossils in this group consist of Swamp j 

 plants, Ammonites, Shells of the Posidono- ; 

 mya, Productus and Spirifer, Fish of the ; 

 Genus Palaeoniscus of Agassiz, Crinoidea or | 

 Stone Lillies, &c, &c, with large foot marks 

 supposed to be of a gigantic Batrachian. 



Old Red Sandstone. 



1. Quartzose Conglomerate. 



2. Cornstone and Marl. 



3. Tilestone. 



This is characterized by its numerous species 

 of Swamp Plants, such as Ferns, Sagillarix, ] 

 Calamites.Lepidodendron, &c, which appear 

 to have grown in a warmer climate than the 

 coal is now found in — there are also found a 

 few fresh water and marine shells, teeth of 

 fish of the Sauroid family of Agassiz. 



This rock is characterized by several species 

 of cartilaginous fish with bony coverings, 

 somewhat like the genus Loricaria of Lin,
