GEOLOGY OF THE ISLE OF WIGHT. 



occasionally thin out rapidly, even within short distances. This 

 may be observed in the case of the bed of greenish sandstone 

 seen in the cliff near Barnes Chine, which is reduced to a 

 thickness of 3 feet where it reaches the shore.

The skull of Vcctisaurus valdcnsis, a Wealden Dinosaur, was 

 found by Mr. Hulke lying on the cliff-foot, 300 yards east of the 

 flagstafE near Brixton (Grange) Chine.* 



Barnes Chine presents a section of red and mottled blue marls. 

 At the top of the eastern bank of the chine, a bone-bed, containing 

 also much lignite, Avas observed by J. Khodes, the fossil 

 collector to the Survey. 



We have now passed over a thickness of 562 feet of strata, and 

 at a point on the beach about 30 yards west of Cowleaze Chine 

 we reach the junction of the variegated beds and the Wealden 

 Shales. The nature of the junction may be gathered from the 

 following section which commences with the thick sandstone so 

 conspicuous in the chine and the long dip-slope of Barnes High. 

 The details were obtained from various points in the cliff below 

 this hill. The section of the same beds as seen at Cowleaze Chine 

 is given on p. 15.
