Canberra, September 26 : New fossils of the first land animals have revealed that ancient shores, 500 million years ago, were alive with more crawling, slithering creatures than anyone previously thought.
According to a report by ABC News, researchers found fossil evidence that slug-like molluscs had slithered through the tidal flats towards land.
In the late Cambrian era, nearly 500 million years ago, the seas were teeming with life. Food was abundant, but so were predators.
Palaeontologists believe animals fled the marine environment for the safe confines of tide pools, and ultimately dry land, where they could live without fear of being eaten.
