Illustration of Ediacara approximately 550 million years ago. Complex life is starting to evolve. In the background are some frond-shaped Charnia. Nearby on the left are three swartpuntia. The three white jellyfish-like organisms on the seafloor are dickensonia. On the seafloor are some sea anemone-like nemiana which may have had tentacles for catching food particles. In the foreground is a kimberella, feeding on the bacterial mats by scratching with its proboscis. Another can be seen further back on the left. At extreme foreground on the left is a tribachidium.
