I02 PROCEEDINGS COTTESWOLD CLUB 1910 



for studying these beds was long ago recognised by Lycett' and 

 Wright : - the latter geologist giving a generalized account 

 and section (text-figure) of beds from the Lower Lias to the 

 top of the Inferior Oolite. 



Ascending Wotton Hill, the first exposure (Wotton-Hill 

 Quarry — IL) is in an old quarry, now much overgrown, on the 

 north side of the road. It shows the top-portion of the Sands, 

 the Cephalopod-Bed, and the basal portion of the Oolite. It 

 has long been known as a locality rich in specimens of Gram- 

 moceras striatuluni (Sow.), and G. toarciense (d'Orb.), and, in 

 my opinion, is the best place in the South Cotteswolds for 

 studying the Cephalopod-Bed and its relations with the sub- 

 and super-jacent deposits. It will be observed that the two 

 rather prominent limestone-bands and intervening marl below 

 the Dispansum-Beds, usuSiWy referred to as the " Stnatultim- 

 Beds,"^ have been more precisely dated. The Scissum-Beds 

 occur at the top of the quarry, and, as at Haresfield, yield 

 Pholadomya fidicula, Sow., and Volsella sowerbyana (d'Orb.) 

 not infrequently. 



There is a gap between this section and the large quarry 

 where the Freestone and Ragstone-Beds have been worked for 

 road-metal ; but the Freestone must be between 30 and 40 feet 

 thick. The beds seen in this second, and very large, quarry are 

 detailed under the heading of " Wotton-Hill Quarry — I." in the 

 record given on page 104. Of previous workers, Mr H. B. 

 Woodward has mentioned its existence,* and the late W. H. 

 Hudleston noticed that the Upper Trigonia-Gnt rested upon 

 the Freestone without the intervention of any Gryphite-Grit ; 

 that Nerinaa Guisei occurred in its usual position in the 

 Clypcus-Gnt ; and that about the middle of the Freestone 

 there was a " slight unconformity in connection with a bed 

 of Nerincea."^ 



The Upper Trigonia-Gnt is not typically developed in this 

 quarry ; but the most interesting points are that there is a 

 layer of lenticular masses of coral on the horizon of the Upper 

 Coral-Bed, and that between it and the Upper Trigonia-Gnt is 

 a thin deposit referable to the Dundry Freestone.
