Dr Howard Falcon-Lang said: ‘It was an amazing experience. We drove down the mine in an armoured vehicle, until we were a hundred metres below the surface. The fossil forest was rooted on top of the coal seam, so where the coal had been mined away the fossilised forest was visible in the ceiling of the mine. We walked for miles and miles along pitch-black passages with the fossil forest just above our heads. We were able to make a map of the forest by the light of our miner’s lamps.’
