28 L. Richardiion — Rhcetic Rocks of Warmckaliire. 



from tlie £2:reater portion of Warwickshire where the true White Lias 

 occurs. There stiff, blackish clays rest directly upon the White Lias. 



IIL Local Details. 



At Marl Cliff the Tea-green Marls are visible, then about 2 feet of 

 black shale, to which follows a layer of sandstone, 1 inch thick, that 

 represents the Bone-Bed.' 



Summer Hill. — Here the East and West Junction Railway passes 

 thi'ough the escarpment of the Rhaitic beds in a cutting. When 

 this railway was constructed an excellent section was displayed; but 

 w^liile Brodie has furnished some information, it is unfortunate that 

 his remarks were not more detailed.'^ 



According to Brodie, the beds dip to the south-east. At the eastern end of 

 the cutting was an " insect-limestone, probably the bottom one of the series ", 

 below which came, in descending order, the Firestone, the Estheria-'BeA 

 (doubtless embedded in the usual greenish-grey Upj)er-RhEetic marls), and then 

 the Black Shales. The Black Sliales were, in the words of Brodie, "loaded with 

 the usual characteristic fossils" at certain horizons;^ but whilst he noticed 

 a " band of blue nodular stone in the shales ", which probably represented the 

 Pecten- Bed, he did not observe any equivalent to the Bone -Bed. Probably 

 it was present as a thin sandstone-layer, like its representative at Marl Cliff 

 and Knowle, near Birmingham. 



The escarpment between Summer Hill and the neighbourhood of 

 Kewnham is well-marked and in places very steep, but there are no 

 exposures of the Rhaetic beds in it. 



North-west of JS^ewnhani, but on the opposite side of the Alne 

 River, are two outliers of Rhaetic beds, namely, those called by Brodie 

 ' Stooper's Wood' and 'Brown's Wood'. 



Stooper's AYood Outlier. — This outlier is composed of Rhajtic and 

 Lower-Lias beds. The quarry referred to by Brodie at Shellfield 

 is overgrown now, and those from which he obtained evidence of 

 the Pecten- and J^stheria-'QeA.?,, the latter containing fragments of 

 Lycojyodites, were characterized as ' old ' by Brodie as long ago 

 as 1865.* 



Brown's Wood Outlier. — Brodie noticed beds similar to those he 

 saw at Stooper's Wood at Brown's AVood.* The ' Insect-Limestones ' 

 appear to have been singularly fossiliferous, containing 



" a great variety of beautifully-preserved insect-remains . . . a few fragmentary 

 plants (including fronds of fern), and a small shrimp-like Crustacean ..." 



Similarly, the Pecten-]iii(\. proved to be highly-fossiliferous, and 

 some of the well-preserved specimens referred to by Brodie ^ are now 

 to be seen in the Warwick Museum. There is also, from the same 

 locality, a piece of limestone crowded with specimens of Estheria 

 minuta var. brodieana.
