*'''485 to 444 million years ago'''
Still a lot of weird critters swimming about in the seas, but the biggest thing at this time were Sea-Bugs. Arthropoids were doing very well at that time, most notably ''Eurypterids''. Imagine a meter long meter long giant sea scorpion. There were also (among other things) a lot of early molluscs such as Orthocones and some rather derpy primitive fish. Fumbling tadpole shaped things with fleshy tails, a lot of boney armor and jawless mouths.

Ends with the Late Ordovician Extinction Event. The first of five such mass extinctions in the paleotological record.
