Lower Greensand. A. (a) Fitton. (b) 1824. (c) Ann. Phil. vol. viii. n.s., p. 371. (d) Greensand. (e) Retained the title green sand because it had “been adopted so very generally by the geologists of England,” but protested that the term was “objectionable, as being derived from a character which is not only very variable, but in reality does not belong to the greater part of this stratum.” [Query—When was “Lower” added to the name?]
