A while ago I found a website that explores fossils in the architecture of Washington, D.C. by Christopher Barr. The site is organized by geological periods and shows examples of fossils that are in stone used in local buildings. I was immediate drawn to the sections on Sacred Heart Church and the Unification Church on 16th Street.
But as I reviewed the site, I suspected that we would also have fossils in the limestone used at the Park View School — and after inspecting the school, my hunch was right. As near as I can tell, the limestone appears to be Indiana Limestone from the Mississippian period. Below are photos of some of the fossils I found at the school.
(An area of trace fossils or, more technically, “ichnofossils”. These are located on the north side of the entry doors on Warder Street.)
(The structures that resemble netting are typically fenestrate bryozoans.)
"The territory comprising Park View extends from Gresham Street north to Rock Creek Church Road, and from Georgia Avenue to the Soldiers' Home grounds, including the triangle bounded by Park Road, Georgia Avenue, and New Hampshire Avenue" (from Directory and History of Park View, 1921.)
