There were plenty of fossilised sea creatures nearly 2,000 feet down at Wearmouth Colliery where I worked. I wish I had got a few now but nobody bothered.
We once had a machine cutting coal and it suddenly bucked like a bronco and every stel box on the drum that held the Tungsten picks were sheared off. Somebody said later that it had been a fossilised tree that had somehow kept its shape and turned into something harder than concrete.
Bought a load of fossillised oak tree last year to slice into nice sample sized pieces, ive only done about half of it cos even with the big diamond saw it takes hours to cut through. Bloody lovely looking stone though all shades of red and yellow with a strange blue/gray coloured bark.
