Geology of Manhattan Skyscrapers

On Sunday, April 3, Jasmine Bayron, Ph.D. student at the CUNY Graduate Center and American Museum of Natural History, led the MSNH on a walk through Central Park. She showed us evidence of glacial recession (which can be seen in the striations of Umpire Rock) and pointed out the erratics left behind by these glaciers. After leaving the park, we examined many small invertebrates in the fossiliferous limestone of Upper East Side buildings. Several of the fossils we observed were bivalves, brachiopods, crinoids and bryozoans.
