What Was the Earth Like 1 Billion Years Ago?

The Earth one billion years ago was a vastly different place than it is today. The supercontinent called Rodinia had just begun to break apart, forming the continents we know today. The climate was much warmer, with no polar ice caps and lush forests covering the land. The oceans were teeming with diverse marine life, including giant sea scorpions and the earliest known fish. The atmosphere was also different, with higher levels of carbon dioxide and less oxygen than today. This warm, wet, and biodiverse planet was home to a wide variety of life, much of which was quite different from anything we see today.
