TKIASSIC SYSTEM. 83 



The Organic Eemains of this System are not very 

 numerous, the deposition of the marls and sandstones 

 appearing to be unfavourable to the development of animal 

 life. Besides the species of fishes which occur in the 

 "Bone Bed," remains of plants and one or two shells 

 {Posidonomya) have been found in the sandstones of 

 Worcestershire and Warwickshire, where, also, impressions 

 of footsteps of animals have been detected, as weU as in Che- 

 shire, the most remarkable being those from Storeton HUl, 

 near Liverpool. The most interesting discovery, however, 

 is probably that by Professor Owen, respecting the bones 

 and teeth from the sandstones of Warwick and Leamington, 

 in which he has proved that their affinity is, not with the 

 Saurian, but with the Batrachian order, and from the 

 complicated texture of the fossil teeth, has proposed the 

 term Lahyrinthodon for the genus to which these remains 

 belong, suggesting at the same time that the foot impres- 

 sions to which the name Cheirotherium had been applied, 

 might have been produced by the above-mentioned 

 creature.
