*'''540 to 485 million years ago'''
There's an explosion in diversity in multicellular life in the seas. Large numbers of invertebrates and the ancestors of every major branch of the tree of life emerge along with a bunch of others which would eventually fade away or be wiped out. A lot of really strange body plans like ''Anomalocaris'' and ''Opabinia'' get tried out. Hell, one Cambrian critter was named ''Hallucigenia'' because paleontologists could literally not make heads or tails of it for decades.
