The '''Oread Limestone''' is a geologic unit of formation rank within the Shawnee Group throughout much of its extent. It is exposed in Kansas, Nebraska, Missouri, Oklahoma, and Iowa. The type locality is Mount Oread within Lawrence, Kansas.<ref>{{cite web |title= Geolex — Unit Summary: Oread |website= National Geologic Map Database |url= https://ngmdb.usgs.gov/Geolex/Units/Oread_9687.html |access-date= 2018-02-24}}</ref> It preserves fossils of the Carboniferous period. Although it has significant shale members, its limestone members are resistant and form escarpments and ridges. Limestone from the unit is a historic building material in Kansas, particularly in the early buildings of the University of Kansas; standing examples include Spooner Hall and Dyche Hall.<ref>{{citation |title= National Register of Historic Places Registration Form: University of Kansas Historic District |publisher= National Park Service |url= https://www.nps.gov/nr/feature/places/pdfs/13000167.pdf |archive-url= https://web.archive.org/web/20170116185754/https://www.nps.gov/nr/feature/places/pdfs/13000167.pdf |url-status= dead |archive-date= January 16, 2017 |quote = Local craftsmen quarried Oread limestone from the north slope of the ridge for the first generation of buildings. }}</ref>
