Name East Liberty applied to bone bed near top of Columbus Formation [now referred to as Columbus Limestone] in an area known as Bellefontaine Devonian outlier, Logan Co., west-central OH. Consists of dolomitic sandstone containing phosphatic nodules, many of which are internal molds of small mollusks and other fossils. Some fish remains also present. Thickness of bone bed commonly less than 1 ft, but arenaceous character of bed extends downward for 10 ft or more, and lower boundary of bone bed is gradational in places. Disconformably underlies Ohio black shale. Age is Middle Devonian.
