Footprint fossils found in Poland
People look at a fossilised footprint of an unknown creature displayed at the Geological Museum in Warsaw January 7, 2010. The fossil dates back to about 400 million years ago which suggests that animals moved from sea onto land at least 20 million years earlier than previously thought.
Fossilised footprints, found in a Polish quarry, of an enigmatic, long-extinct creature have prompted palaeontologists to reopen the file of how life in the sea moved to the land.
