Vocab: - Eon: a major division of geological time, subdivided into eras. A unit of time equal to a billion years. - Era: a long and distinct period of history with a particular feature or characteristic. Divided into periods - Period: Large interval of time that is meaningful because of it’s characteristics Sequential Time: the order of events in a sequence (ex: you woke up before your brushed your teeth.) Numerical Time: The actual time that events occurred. (Ex: I woke up at 5:30 & brushed my teeth at 5:33.)

The Archaen Eon Crust cools & Plate tectonics is established Atmosphere composed of nitrogen, hydrogen, carbon, but very little oxygen The first life appears and forming the earliest fossils Complex chemical reactions change carbon molecules into earliest life forms First photosynthetic organisms produce oxygen

Proterozoic Eon Protero= first Zoon= life in Greek First multicellular animals by end of interval Larger land masses form from the accretion of smaller ones 4 major mountain-building episodes

Continents begin to erode into oceans creating marine environments where life could diversify Increasing oxygen in the atmosphere caused some life forms to go extinct, while allowing others to flourish Oldest known glaciations

Paleozoic Era & Cambrian Period 542-488 mya Cambrian Explosion of life forms Skeletonized animals (exoskeletons) Early animal diversification Diversification of trilobites Burgess Shale fauna (fossils of soft bodied animals) Warming climates Plate tectonics

Trilobite diversification
