Oldest Land-Walker tracks found
The first vertebrates to walk the Earth emerged from the sea 18 million years before than thought, say scientists who have discovered footprints from an 8-foot long prehistoric creature. Dozens of 395 million year old fossil footprints have been rezcently discovered in a former lagoon in South-eastern Poland. The prints were made by Tetrapods [animals with backbones and 4 limbs] and could rewrite the history of when, where, and why fish evolved limbs and first walked onto land, the study says.
The tracks were made by species which had digits or toes on each foot. The footprints vary in size, some being as wide as 10 inches. Track size indicate flat bodied, lizard like creatures 8.2 feet long and with stout legs. These were discovered in an abandoned mountain quarry.
