NEW RED SANDSTONE. 



lower portions of these beds near Sidmouth, and there also Plant- 

 remains {Equisetiies ?) have been found by Mr. P. O. Hutchinson.^ 



The underlying Upper Sandstones are generally composed of 

 red rock, often false-bedded and in places mottled with greenish- 

 grey streaks and patches, and they contain hard nodules and 

 ferruginous concretions. Such beds are well shown near Williton, 

 Halse, Milverton, Minehead, Wellington, Kentisbere, and Ottery 

 St. ]Mary, as well as on the coast near Sidmouth. Near Williton 

 the beds are very calcareous, and are burnt for lime. After a study 

 of the red rocks near Minehead and Williton (1870-73), Mr. J. H. 

 Blake came to the conclusion that the three divisions of the Trias 

 were present, and he correlated the calcareous sandstones, well 

 shown between Crowcombe Heathfield and Bishops Lydeard, with 

 the Muschelkalk.* (See p. 221.)

False-bedded red, brown, and 3'ellow sandstone, with pebbly seams (Upper Sandstone). 



In the sandstone series of Otterton Point Mr. Whitaker found 

 the jaw of Hyperodapedon, a lacertilian reptile about six feet long ; 

 and more recently in the higher portion of the same series of beds, 

 between Budleigh Salterton and Sidmouth, bones of Labyrinthodon 

 have been discovered.^ 



Beneath the Upper Sandstones come beds of Conglomerate 

 with large pebbles of grit and limestone, as at Tipnoller and other 

 quarries east of Wiveliscombe, Vellow near Stogumber, INIilverton, 

 and Wellington ; sandstone bands frequently occur between the 

 beds of conglomerate. Between the sandstone and conglomerate 

 there is often no hard line of demarcation ; south of IMilverton,
