Epoch 3 was a time of major intraclade expansion of bilaterians or animals with bilateral symmetry (Babcock).
Epoch two experienced early diversification of marine animal clades, most notably among the arthropods (Babcock).

During this period, Earth's landmasses were mostly barren, with shallow seas covering much of the planet. The climate of this period was also relatively warm but had possible glacial-interglacial cycles in the later portions (Peng).
The Cambrian Period saw a rapid explosion of life in the oceans, also known as the Cambrian explosion. This explosion leads to a massive diversification of marine animals emerging on to the planet's ecosystems.
