GAULT.

■A M 







besides which there are remains of Saurians {^Ptcrodaciylus, etc.), 



and Chelonia. Prof. T. R. Jones 

 ^ ^, has noticed an Annelide-bed in the 



Gault near Charing, Kent. In his 

 opinion the Foraminifera indicate 

 that the beds were deposited in a 

 depth of about one hundred fathoms.^ 



To the west of Reigate the Gault 

 appears much reduced in thickness, 

 although the breadth of its outcrop 

 is naturally diminished by the higher 

 inclination of the strata.^ A section 

 of Gault has been exposed at the 

 Varnes, on the banks of the Med way, 

 near New Hythe. Many fossils have 

 been obtained at Bletchingley. In 

 East Sussex fossils have been found 

 in the neighbourhood of Ringmer ; 

 and the railway-cutting near Alton 

 has also yielded specimens. 



In the Isle of Wight the Gault 

 has received the name of the ' blue 

 slipper,' from the tendency of the 

 overlying strata to slip or slide over 

 its surface ; and in this way the 

 beautiful scenery of the Undercliflf 

 has been mainly produced. It has 

 a thickness of 100 feet in Compton 

 Bay.3 



In Swanage Bay the Gault is seen 

 on the shore near Punfield Cove, 

 and is there represented by about 

 thirty feet of bluish-green sandy 

 clay. (See Fig. 54, p. 347.) It may 

 be traced in Mewps Bay, and was 

 noticed in Lulworth Cove by Dr. 

 Fitton, where it is represented by 

 dark, greenish, sandy strata, with 

 large concretionary nodules.* It has 

 also been recognized at White Nore, 

 further west, though, from the ac- 

 cumulation of tumbled rock, it is 

 not always visible.* 



The Gault has been traced in 

 places as far as Black Ven, Lyme
