360 WILMORE : THORNTON, MARTON AND BROUGHTON-IN-CRAVEN. 
The small cuttings at Langber and at Haw Pasture, (12) on 
the map, have furnished very few fossils. Small specimens of 
Athyris, probably planosulcata, and a small Chonetes being the 
only recognisable shells obtained, but fragments of Syrmgopora 
were also seen. 
As the anticline is followed to the east it is found to be cut 
transversely by the brook, as already mentioned. The northern 
limb forms a well-marked ridge, extending from Broughton 
Fields to Broughton village, and in that ridge is a series of quarries, 
in which the beds have a steady north-westerly dip. They are 
numbered (13), (14), (15) on the sketch-map. In number (15) 
there is considerable disturbance, two small faults and some folding 
of the beds being seen. In number (13), the quarry at Broughton 
Fields, Syringopora is very common, and on the dip-slopes may 
be seen lenticular masses from six inches to a foot in diameter. 
Similar masses are seen in the calcareous shales at Rain Hall. 
(See note on Syringopora on page 368.) Other fossils are not 
common ; but such as I have obtained seem exactly like those 
of Rain Hall. 
The beds in the whole of the exposures in this long anti- 
cline are of the same general type — calcareous shales, thin 
earthy limestones, massive dark-blue to black limestones, and 
subordinate grey crinoidal limestones being everywhere seen. The 
shales are characterised by the same general fauna, and the dark- 
blue and black limestones, when sectioned, present very similar 
features. Foraminifera are very plentiful. This is the case at 
the western end of the anticline, as at the Punch Bowl Hill and 
Gill Rock on opposite sides of the arch, and at Broughton 
Fields much further east. I have added a section from the 
well-known quarry at Raygill, Lothersdale, some 2h miles 
south of the southern limb of the Thornton anticline (Plate 
XLIIL, Fig. 1). It mil be seen that the sections of these rocks 
show very similar characters to those of Thornton and district. 
W ith regard to the precise stratigi'aphical position of the 
beds in this anticline, it must be pointed out that there is nothing 
like a continuous section, and that the beds are evidently very 
much disturbed. Still I think there is little doubt that they are 
of Upper Dibunophyllum age, probably corresponding with
