See () considered that miospore occurrences from the Mississippian of the Michigan Basin are unlike those described by Winslow () and may be closer to the Horton Group of Nova Scotia (Hacquebard, ).

This report will provide evidence for the occurrence of the Kinderhookian–Osagean boundary within the Michigan Basin based on Cited eastern Canada book 4.

Unit Name: Horton Group Unit Type: Lithostratigraphic Rank: Group Status: Formal Usage: Currently in use Age Interval: Middle Devonian - Early Carboniferous ( - Ma) Age Justification: Based upon a sparse macroflora, Bell () correlated the Horton Group with the Tournaisian of Europe and the early Mississippian Pocono Formation of the eastern USA.

Comments: The holotype from the early Mississippian Horton Group of Eastern Canada has been refigured (but not redescribed) by McGregor and McCutcheon (, text-fig. 4f, pl. 3, fig. 15). They also illustrated the shape and size of the ornament on the holotype (– μm in basal width and up to μm in height).Cited by: boniferous System in eastern Canada: Canadian Record of Science, v.

Taxonomic discussion: ld. nitidus was first described and named from the Tournaisian Horton Group of eastern Canada by Playford (). Shortly afterwards Sullivan () described specimens from the Tournaisian Lower Limestone Shales of southwest England identical to the species which he called Verrucosisporites grumosus (Naumova) Sullivan.

In eastern Canada, however, a dry climate prevailed. Uppermost Visean to Lower Namurian (NC-SO zones): Climatic condi- tions became increasingly more humid in Western Europe and Central North 13 America, although not yet as humid as in the Upper Tournaisian to Middle Visean of Northern Euramerica.

The Walton barium deposit with associated Cu-Pb-Zn-Ag mineralisation is a carbonate hosted occurrence in the lower Carboniferous (Mississippian) Windsor Group, and is located 70 km NW of Halifax in Nova Scotia, Canada.

Well-preserved Lower Mississippian (Dinantian) miospore assemblages have been recovered from the upper Cuyahoga Formation (type Wooster Member) and overlying lower Logan Formation (Byer Member) at two localities in Wayne County, northeastern Ohio, USA.
