Smith for a thin See also:band of shelly See also:limestone which, in the See also:south of England, breaks up in the manner indicated. Although only a thin See also:group of rocks (10–25 ft.), it is remarkably persistent; it maybe traced from See also:Weymouth to the See also:Yorkshire See also:coast, but in See also:north See also:Lincolnshire it is very thin, and probably See also:dies out in the neighbourhood of the See also:Humber. It appears again, however, as a thin See also:bed in Gristhorpe See also:Bay, Cayton Bay, Wheatcroft, See also:Newton See also:Dale and Langdale. In ,the inland exposures in Yorkshire it is difficult to follow on See also:account of its thinness, and the fact that it passes up into dark shales in many places—the so-called " See also:clays of the Cornbrash," with Avicula echinata.
The Cornbrash is a very fossiliferous formation; the .See also:fauna indicates a transition from the See also:Lower to the See also:Middle Oolites, though it is probably more nearly related to that of the beds above than to those below. Good localities for fossils are Radipole near Weymouth, Closworth, Wincanton, See also:Trowbridge, See also:Cirencester, See also:Witney, See also:Peterborough and Sudbrook See also:Park near See also:Lincoln. A few of the important fossils are; Waldheimia lagenalis, See also:Peden See also:levis, Avicula echinata, Ostrea flabelloides, Myacites decurtatus, Echinobrissus dunicularis; Macrocephalites macrocephalus is abundant in the midland counties but rarer in the south; belemnites are not known. The remains of saurians (Steneosaurus) are occasionally found. The Cornbrash is of little value for See also:building or road-making, although it is used locally; in the south of England it is not oolitic, but in See also:York-See also:shire it is a rubbly, marly, frequently ironshot oolitic limestone. In See also:Bedfordshire it has been termed the See also:Bedford limestone.
