Flora From Minto Area (Carboniferous to of Canada)

Where: New Brunswick, Canada (46.1° N, 66.1° W)

• Paleocoordinates: 26.3° S, 21.1° W (Wright 2013)

• coordinate stated in text

When: Vestispora other zone, Upper Member (Minto Formation), Westphalian C to Westphalian C (314.6 - 307.4 Ma)

• Originally in Pictou Group. However, Miller & Forbes (2001) note that Minto now is in the Cumberland group. Was originally "Carboniferous" for age, but Miller & Forbes (2001) note that it is early Wesphalian C in the Vestispora Atlantic Canada zone (= Torispora securis- Torispora laevigata Zone of western Europe & lower Torispora securis- Vestispora fenestrata Zone of Illinois.)

• group of beds-level stratigraphic resolution

Environment/lithology: mire or swamp; coal

• The Minto Formation is described as including fossiliferous sandstone, conglomerate, siltstone, shale and coal (St. Peter 1997). The Minto Formation is subdivided into two informal members (Muller 1951; Hacquebard and Barss 1970; Williams et al. 1985). The lower member consists of a grey, buff-weathered, commonly cross-bedded, quartzose sandstone, a pebbly sandstone, and a conglomerate. The upper member includes a greyish-green to buff coloured sandstone, a light grey mudstone and the ‘Minto coal seam’.

Size classes: macrofossils, mesofossils, microfossils

Preservation: adpression
