248 NORTH STAFFORDSHIRE COAL FOSSILS. 



found, but no complete specimen has yet occurred. These 

 remains have been collected chiefly from the Rag mine 

 and Chalky mine ironstones at Fenton. The occurrence of 

 Labyrinthodonta in beds highly charged with fish remains 

 is of great interest. No doubt these creatures lived in 

 the marshes or amongst the rank and luxuriant foliage 

 which grew upon the banks of the rivers or seas of that 

 period. That they made frequent visits, no doubt in quest 

 of prey, to the waters in which fishes lived, is evident 

 from the fact that in the beds above-mentioned remains of 

 both fishes and reptiles are found commingled. The dis- 

 covery of reptilia in this coalfield is not of recent date. 

 A single tooth of one of these creatures is figured in Mr. 

 Garner's "Natural History of Staffordshire." (Plate E, 

 fig. 13.) Within the past ten or twelve years specimens 

 representing three or four additional genera have been 

 found. These, in consequence of the limited state of our 

 knowledge, at that time, of animals of this class were thought 

 to be the remains of Rhizodus and other sauroid fishes. 

 It is only within the past few years that their true character 

 has become known.
