Spectacular Fossil Forests Found In US Coalmine
Smivs passes along a report up on the BBC about the fossil forests found in coal mines in Illinois. "The [US-UK] group reported one discovery last year, but has since identified a further five examples. The ancient vegetation — now turned to rock — is visible in the ceilings of mines covering thousands of hectares. These were among the first forests to evolve on the planet, [according to] Dr. Howard Falcon-Lang... 'These are the largest fossil forests found anywhere in the world at any point in geological time. It is quite extraordinary to find a fossil landscape preserved over such a vast area; and we are talking about an area the size of [the British city of] Bristol.' The forests grew just a few million years apart some 300 million years ago; and are now stacked one on top of another."
are the places where there is both coal and limestone. The same place that was once a forest that got fossilized then got covered by the sea. Scratch through the limestone and you find fossilized sea shells etc. Go deeper and you find fossilized twigs and leaves.
Engineering is the art of compromise.
