﻿Yol. 6 1.] BLEA WFKE BEDS IN" NORTH-EAST YORKSHIRE. 453 



IV. Inland Sections. 



(1) Falling Foss and Littlebeck. 



Along the east side of this valley are a few exposures of the 

 Dogger, from which many fossils can be obtained. 



At Falling Foss, by the side of the waterfall, the succession is : — 



Thickness in feet. 

 Estuarine Series above. 



Fine-grained ferruginous sandstone 8 



Coarse red rock, with pebbles and white fragments ; 



many fossils 4 



Blue Liassic shale below. 



The 4-foot bed consists of a coarse, reddish-grey, conglomeratic 

 rock, containing numerous angular white fragments. This is 

 exactly like the rock seen at the Peak alum-works and many 

 other localities. The fossils are not in good preservation, but the 

 following can be identified : — 



Pentacrinus. 



Ceromya bajociana. 

 Modiola plicata. 

 Pecten arcuatus. 

 Pecten barbatus. 

 Pecten demissus. 

 Avicula Munsteri. 

 Cardium striatulum. 



Pleuromya sp. 

 Sowerbya. 



Cerithium muricatum. 

 Pseudomelania procera. 

 Alaria arenosa. 



Belemnites. 



In a small stream, half a mile north of Newton House, the 

 following interesting section is exposed : — 



Thickness in feet. 

 An extremely-variable bed, in some parts a coarse 

 pebbly grit, in others a yellow sandstone, or even an 



oolitic ironstone becoming flaggy at the top 12 



Soft yellow sandstone, weathering into concentric 



ferruginous coats 2£ 



Pebble-Bed, with badly-preserved fossils 1 



Soft yellow sandstone l£ 



Blue Liassic shale, very rotten. 



The Pebble-Bed consists of unusually-large pebbles, measuring up 

 to 1^ inches in diameter, of the ordinary character. The fossils, 

 although very numerous, are badly preserved. The following are 

 determinable : — 



Trigonia striata. 

 Pecten 

 Pinna sp. 

 Pholadomya. 



Pseudomelania procera. 

 Turbo ' 



Belemnites. 



And a fragment of an ammonite, probably derived. 



In the Littlebeck alum-works the lower part of the Dogger is 

 very fossiliferous ; it is, for the most part, the peculiar red conglo-
