The fossils you'll see at Lester Park are called stromatolites ("layered rocks"). They were constructed by "blue-green algae" on a shallow sea floor that is now exposed. While they were growing, New York and the eastern US lay south of the equator. The stromatolites at Lester Park were the first described in North America and remain a valuable teaching aid for college and university classes nationwide.
