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
