Extract

The distribution of the Rhætic rocks in Warwickshire is not represented on the existing Geological Survey maps because at the time that the survey was made their distinctness from the Lower Lias was not appreciated, and therefore they were represented by the same colour.

page 27 note 2 Brodie states (Trans. Woolhope Nat. F.C., vol. for 1866, p. 212Google Scholar) that it is worthy of note that in one of the more westerly sections at Wilmcote “all the insect beds thin out and scarcely amount to three layers, the top band being irregular and shattered; a thick mass of shale succeeds, undivided, as elsewhere, by limestones, and below are three beds of limestone, viz., the firestone, with Ostrea liassica, but of a very different character”. From Brodie's record of the Wilmcote section (loc. cit. supra, pp. 210–11)Google Scholar it is clear that the limestones in which he found insect-remains most abundantly came above the deposits in which saurian-remains are commonest, and are clearly of planorbis date.

page 27 note 3 Brodie complains that his name of “Insect Beds” was ignored by Wright, who applied the term “Saurian Beds” to them (Trans. Woolhope, Nat. F.C., vol. for 1866 (1867), p. 210).Google Scholar
