It was a steamy tropical land south of the equator; swamps, mountains, high rainfall, a primal jungle teaming with the land-pioneers – insects. Amphibians came ashore to harvest the vegetation and insects and some evolved to stay on land. They were the very first vertebrates to colonise the land; lizard-like Tetrapods crawling and slithering through the mud. The high rain fall brought floods of silt from the mountains, quickly filling and burying the tracks of the Tetrapod.
