    The first 2 Eons Archean and Proterozoic , represent this Precambrian time period. All organisms of this time had soft bodies with no shells or skeletons. Ex Worms and sponges. Oceans fill with diversity of life Cambrian period: Amphibians left water for land -large water reptiles emerge -Dinosaurs emerge.

    This sharp division in time is the K T boundary -Dinosaurs and many other groups go extinct here million years ago. Many periods named after geographic locations. Are time divisions of a period. The processes concerning mountain building, erosion, and sea level changes that are occurring today have been occurring since Earth formed. Places rocks and events that formed them in order, but without exact dates.
