Thomas A. Greene Memorial Museum is a museum that showcases fossils amassed during the decade of 1880 to1890. It is a fireproof building designed to preserve the mineral and fossil collection of Thomas Greene. In 1993 the collection was transferred to the Lapham Hall in the University of Wisconsin ? Milwaukee. The fossil and mineral collections are made up of specimens from the Silurian Niagara Foundation and the Devonian Hamilton Foundation. These fossils are preserved and molded in dolomite. Here is some of the Silurian Fossilized collection: trilobites, corals, crinoids, tabulate and others. Some Devonian fossils are the remains of plants and fishes, which were collected from outcrops of old quarries.

The mineral collection was obtained from the sites throughout North America. It includes samples of exquisite amethyst, copper, tungsten, cobalt, nickel, apatite, molybdenum, and beryl among others. A piece of iron meteorite which landed in Washington County is an interesting piece in the collection. The present curator of the museum is Dr. Stephen Q. Dombos, an Associate Professor of Geosciences at UWM and a paleontologist. A trip to the museum is a trip to the past.
