[7] [8] Different styles of stromatolite lamination have been described, [9] [10] which can be studied through microscopic and mathematical methods. [10] A stromatolite may grow to a meter or more. [11] [12] Fossilized stromatolites provide important records of some of the most ancient life. As of the Holocene, living forms are rare.
Modern stromatolites are relatively small, Hynek said, whereas ancient stromatolites used to grow to 20 feet (6 meters) tall and 16 to 22 feet (5 to 7 meters) wide, he said.
Stromatolites are alternating layers of cyanobacteria and sediments. The grain size of sediment portion of stromatolites is affected by the depositional environment. During the Proterozoic, stromatolites' compositions were dominated by micrite and thinly laminated lime mud, with thicknesses no greater than 100 microns. [3]

By far the most common of these three types were branching bryozoans, which can be found by the hundreds at almost any Devonian marine site. These types are named for their slender, branch like shape and how they grow together in small forest-like groups. Encrusting bryozoans are also very common animals and are often found with brachiopods.
