1 Fossils and Earth’s Geologic History PRESENTED BY: MARK A. VAN HECKE ANCHOR BAY HIGH SCHOOL NEW BALTIMORE, MI

2 ALL GEOLOGIC TIME IS DIVIDED INTO TWO EONS PHANEROZOIC FROM 570 MILLION YEARS AGO TO THE PRESENT PRECAMBRIAN EON FROM 3.4 BILLION YEARS AGO TO 570 MILLION YEARS AGO

3 EACH EON IS DIVIDED INTO PERIODS ONLY THE PHANEROZOIC IS DIVIDED INTO PERIODS, THE THREE YOU NEED TO KNOW ARE PALEOZOIC MESOZOIC CENOZOIC

4 EACH OF THE ERAS IN TURN IS DIVIDED INTO PERIODS

5 PALEOZOIC ERA CAMBRIAN ORDOVICIAN SILURIAN DEVONIAN MISSISSIPIAN PERMIAN

6 MESOZOIC ERA TRIASSIC JURASSIC CRETACEOUS

7 CENOZOIC ERA TERTIARY QUATERNARY

8 PERIODS IN TURN ARE DIVIDED INTO EPOCHS

9 THE PERIODS OF THE PALEOZOIC AND MESOZOIC ARE SIMPLY DIVIDED INTO EARLY, MIDDLE AND LATE EPOCHS

10 EPOCHS OF THE CENOZOIC ERA ARE GIVEN DISTINCTIVE NAMES IN EACH OF THE PERIODS

11 TERTIARY PERIOD PALEOCENE EOCENE OLIGOCENE MIOCENE PLIOCENE

12 QUATERNARY PERIOD PLEISTOCENE HOLOCENE (PRESENT)

13 MOST GEOLOGISTS THINK THAT THROUGHOUT IT’S HISTORY EARTH’S CLIMATE HAS SEE- SAWED BETWEEN A ‘HOT HOUSE’ AND AN ‘ICE BOX’ CLIMATE
