Type material of Paraconularia planicostata (Dawson) from the Upper Mississippian of Nova Scotia, Atlantic Canada
Paraconularia planicostata (Dawson, 1868) is one of two species in this genus (Sinclair, 1940) of conulariid cnidarian currently known from Mississippian strata in the Maritimes Basin in Atlantic Canada (Babcock and Feldmann, 1986). A salient characteristic of the species is the presence of a low an...
