Cambrian Explosion

The fossil record shows that 600 million years ago in the Precambian period life began to evolve rapidly. Then, about 570 to 530 million years ago there was another burst of diversification that is responsible for the appearance of many lineages of species that are still present today. This burst of life is known as "the Cambrian Explosion." Some of the species that appeared during this period are:

Marella

Waptia

Opabinia

Hallucigenia

Wiwaxia

Anomalocaris
