MOORS, COAL FIELD AND LIMESTONE RIDGE; West Yorkshire's landscape gets its character the underlying rock.
On the whole plants are rare in the fossil record, but Coal bearing rocks give a rare glimpse of long vanished tropical forests. The county's creamy coloured Limestone formed in a dying sea while, millions of years before, the tough Millstone Grit of the Pennines were laid down in vast river deltas.
