202 DAVIS : SECTIONS IN THE LlASSIC AND OOLITIC ROCKS OF YORKSHIRE. 
Further north the Cornbrash may be seen at the base of the 
Kelloways Rock, in the valleys at Hackness, and on the sides of the 
Langdale Gorge and in other localities. An outlier occurs on the 
moors of Fylingdale at Blea Hill. An outlying piece of the rock may 
be seen along the north cliff at Scarborough. 
The Kelloway Rock is a thick bedded sandstone, soft and of a 
brownish-yellow colour, due to iron ; except a red calcareous band in 
its upper beds with fossils, the Kelloways are generally unfossiliferous. 
Towards the base the beds become more argillaceous, and pass in- 
sensibly and without break into the blue clays of the Cornbrash 
below. The Kelloway Sandstone first appears and forms a projecting 
reef at low water at Newbiggin Wyke. In this locality it is scarcely 
6 feet in thickness, but it rapidly expands northward, and a short 
distance further on, in Gristhorpe Cliff, the beds have attained a 
thickness of 30 feet, and in the North Cliff, at Scarborough, they are 
75 feet. After forming a distinct feature in the south-west end of 
Gristhorpe Bay the Kelloways are hidden by the boulder clay of the 
coast, until they again appear high in the cliff on the eastern side of 
the fault in Red Cliff*. Further north, it can easily be traced by the 
projecting feature it makes on the sides of the hills west of Scar- 
borough. It has been quarried at several places, and has been used 
in the erection of the Scarborough Museum, and also the one at York. 
It is a very durable stone and hardens with exposure. In the valleys 
westward from Scarborough, about Hackness and district, surmounted 
by the Calcareous Grit, this rock usually forms a prominent feature 
about half-way down the escarpment. It comes to the surface north- 
westwards, and forms moorlands reaching a height above the sea level 
of 950 feet. 
The following fossils have been obtained from the red calcareous 
band referred to above : — 
Rhychonella Thurmanni, Voltz. Goniomya liberata, Sow. 
R. socialis. Myacites recurvus, Phil. 
Waldheimia ornithocephala, Sow. Myacites calceiformis, Phil. 
Ostrea flabelloides, Lam. Gresslya peregrina, Phil. 
Gryphaea dilatata, Sow. Pleurotomaria guttata, Phil. 
Pecten fibrosus, Sow. Ammonites modiolaris, Sherid.
