Silurian Life. The Silurian saw rising sea levels due to glacial melting. Life was still predominantly marine, but the first unequivocal terrestrial fossils are found in Silurian strata. Arachnid and centipede fossil are found. Perhaps most important is the appearance of vascular.
Devonian Life. The Devonian period brought significant diversification of terrestrial life, including the first vertebrates, the amphibians, and the first forests of trees appeared; this completed a land colonization process that likely started in the late Cambrian. Dunbar, C.O.

The Cambrian Period was followed, million years ago, by the Ordovician Period. At that time many species died out, to be replaced by new ones in another evolutionary “explosion”, called the Great Ordovician Biodiversification Event (or GOBE). During the Ordovician, the seas surrounding North America and Europe became rich in life, especially trilobites, brachiopods and reef-forming corals.
