Plants of the Horton Series or Lower Carboniferous Coal Measures (Carboniferous of Canada)

Where: New Brunswick, Canada (45.0° N, 64.0° W: paleocoordinates 16.4° S, 14.1° W)

• coordinate based on political unit

When: Mississippian (358.9 - 323.2 Ma)

Environment/lithology: sandstone and calcareous shale

• The Horton Bluff Series or Lower carboniferous Coal-Measures, consisting of hard sandstones and shales often calcareous, associated with conglomerate and grit, and in some places with highly bituminous shales. They contain underclays and thin coaly seams, remains of Plants, Fishes and Entomostracans, and foot-prints of Batrachians, but no strictly marine remains.

Collection methods: Sir C. Lyell first established the Horton Bluff Series or Lower Carboniferous Coal-Measures group as a distinct sub-division of the Carboniferous in Nova Scotia. Dawson identifies the following locations as equivalents of the Lower Carboniferous Coal Measures or Horton Series: the Vespertine Group of Rogers in Pennsylvania, the Kinderhook Group of Worthen in Illinois, The Marshall Group of Winchell in Michigan, the Waverley Sandstone of Ohio, the Lower or False Coal Measures of Virginia, the Calciferous Sandstones of McLaren or Tweedian Group of Tate in Scotland, the Carboniferous Slate and Coomhala Grits of Jukes in Ireland, the Culm and Culm Graywacke of Germany, the Graywacke or Lower Coal-Measures of the Vosges,the Older Coal-Formation of the Ural, and the so-called "Ursa Stage" of Heer.
