GEOLOGY OF THE EAST CLIFF. 135 



The Fairlight Clays are essentially a 

 plant Formation, though fishes and reptiles 

 are occasionally found ; also the footprints 

 of Iguanodon* at various horizons, and 

 ripple-marks. 



Thickness of beds (bottom not known) 

 360 feet. 



FORMATION No. 2. 



ASHDOWN SANDS. 



About 14 feet above the East Groyne, 

 and overlaying the pale blue clays which 

 indicate the top of the Fairlight Clays, there 

 is a change into red buff Sandstone. For the 

 first (lowest) 43 feet it is of rather a loose

 contrast to the thick perpendicular bed above, 

 at the junction with which there is a thin 

 parting from 12 inches to 18 inches of
