EARTH SCIENCE  - EARTH'S HISTORY

PROBLEM: How can you use fossils to date and determine the paleoenvironment of an area?

HYPOTHESIS:

MATERIALS: Earth Science - Fossils

PROCEDURE:

1.  Look at the range chart from the reader and determine the age of this specimen. 

FOSSIL LOCATION AGE RANGE
Turritella (gastropods)   Maryland
Shark tooth   Morocco
Crinoid Stems Morocco
Belemnite Morocco
Ammonite Morocco
Brachiopod Morocco
Sea Urchin Spine Morocco
Trilobite Morocco
Coquina Florida
Fish Nevada or Wyoming
Mollusk Capitola, California

2.  Look at the fossils and try and interpret what kind of environment existed when these animals where present in that area.  Try and determine if it was deep ocean water, shallow water, shallow marine, or even fresh water like a lake.
