Trilobite and Brachiopod Fossils

I found these fossils while hiking around Thatcher Park.  The park is part of the Helderberg Escarpment, one of the richest fossil-bearing formation in the world.  It is about six miles of limestone cliff-face and rock-strewn sloes overlooking the quaint town of Altamont. 

These fossils are from the Devonian period which was known as "The Age of Fish."  For you Christians, it is called "The Fifth Day."  From Genesus 1:20:

And God said, Let the waters bring forth abundantly the moving creature that hath life

And the evening and the morning were The Fifth Day

For an extremely informative academic report on the geological data of the area, Union College of Schenectady put out this document:
