The animals in the Precambrian Period were soft bodied animals. This Era was dominated by single celled organisms: algae, bacteria. Also in existence were jellyfish, spiders, crabs, and worms.
What kind of animals developed near the end of first era?
Animals without backbones, called invertebrates, developed near the end of the Precambrian. Imprints of jellyfish and marine worms have been found in late Precambrian rocks.
