The Killey Bridge Formation is a geologic formation in Northern Ireland. It preserves fossils dating back to the Ordovician period.
The Everton Formation is a geologic formation in northern Arkansas that dates to the middle Ordovician Period. Unconformities separate this formation from the underlying Powell Formation and the overlying St. Peter Sandstone Formation. Named for the town of Everton in Boone County, Arkansas in 1907, the Everton Formation is composed primarily of dolomite, limestone, and sandstone.
The Glencar Formation is a geologic formation in Northern Ireland. It preserves fossils dating back to the Carboniferous period.

The Blackwater Limestone is a geologic formation in Northern Ireland. It preserves fossils dating back to the Carboniferous period.
The Blackstokes Limestone is a geologic formation in Northern Ireland. It preserves fossils dating back to the Carboniferous period.
The Bardahessiagh Formation is a geologic formation in Northern Ireland. It has been described from a locality lying about 3 km NNE of Pomeroy, south of Craigbardahessiagh. It is now known as comprising the former ‘Bardahessiagh Formation’, or Bardahessiagh Beds and the ‘Junction Beds’ that is underlain by a stratigraphical unit not recognised, until fieldwork by the Ulster Museum staff in 1992. The Bardahessiagh Formation is divided into three units, but the summit of the formation is not known. Field evidence indicates that the local top of the formation is characterised by a thrust contact with the Killey Bridge and Tirnaskea Formation, exposed south of the Well Field, which lies 650 metres SSW of Craigbardahessiagh.
