Florida geologic history begins deep benearth its surface where ancient rock indicate that Florida was one a part of Northwest Africa. The sea was favorable to the existence of shell life , the remains accumulating to form shell rock ; hence in the early history of Florida in paticular a large amount of lime and shell rock accumulated. In Florida , sedimentary rock are the most common type of rock. These rocks are made up of cemented mineral particles. One example is shell fragments ( the mineral arrgonite) that are cemented together by calcite to form the sedimentary rock coquina.Since Florida is relatively a young terrain , its basement rock is composed of carbonate remains of marine algae and shells deposited in an ancient sea. Evidence indicates earliest geologic formations begain during the Tertiary Eocene era. As glaciers of ice in the north expanded and melted , the Florida peninsula emerged and submerged. When the sea level was lowest , the land area of Florida was much larger than it is now . Florida was as much as three times the current land area as it is today during the last ice age.
Arriving at the coods you shall see coral rock along the water's edge, in this coral rock you shall see seashells and other marine life. Have fun looking at all the different marine life that you can find in this one place.

MOLLUSKS:
ARE MOST OFTEN REPRESENTED BY TWO MEMBERS; PELECYPODS---ARE SIMILAR TO MODERN CLAMS WITH TWO IDENTICAL SHELLS.
