This report covers 5 collections, 4 of them of Mississippian age and other possibly Devonian. Two of the collections (83DN422 and 431) are almost certain from the Kayak Formation of early Mississippian age. Two others (83PA324, 343), probably from Lisburne Group rocks, are also Mississippian but contain no definitive megafossils. The fifth collection (83PA261a) is a dark-gray dolomite that does not appear to be a representative Lisburne rock type. Although there are no identifiable fossils, I suggest that it is possibly Devonian. 4 collections retained.
