Description: Stromatolitic limestone - glacially planed-off outcrop of Hoyt Limestone in the Cambrian of New York State, USA. Stratigraphy: Hoyt Limestone, Upper Cambrian Locality: low outcrop on eastern side of Lester Park Road (Petrified Sea Gardens Road), north of Rt. 29, west of the town of Saratoga Springs, western Saratoga County, eastern New York State, USA. Stromatolites are large, layered structures built up by mats of cyanobacteria. Stromatolites vary in appearance, ranging from slightly wrinkled horizontal laminations in sedimentary rocks to low mounds to prominent mounds to columnar structures and other forms. Stromatolites are most common in the Proterozoic fossil record. They are scarce today, but famous modern examples occur at Shark Bay, Western Australia.
