Ichnology of the Pennsylvanian-aged Boss Point Formation at Cape Enrage, New Brunswick: Implication for the paleoenvironmental context for the Lower Boss Point Formation in the Cumberland Subbasin of the Maritimes Basin
(University of New Brunswick, 2024) Hannberg, Alexia T.; Wilson, Lucy; Stimson, Matthew
The Langsettian aged Boss Point Formation (i.e. ~320 million years old) outcrops at Cape Enrage in southeastern New Brunswick along the shores of the Chignecto Bay, Bay of Fundy. Although traces have been noted from the type section at Joggins Nova Scotia, newly discovered invertebrate repichnia tracks at Cape Enrage represent the first ichnofossil assemblage to be systematically described from the Boss Point Formation in Atlantic Canada. The tracks described in this thesis include: Diplichnites, Diplopodichnus, Kouphichnium, Protichnites, Selenichnites and Stiaria. Given the presence of some diagnostic ichnotaxa, some of the lithofacies can be interpreted as shallow coastal and channel bar lithofacies conformable to the poorly-drained to openwater lithofacies assemblage transition described from the Joggins Formation. The implications of this ichnoassemblage, specifically the presence of horseshoe crab traces, indicate that the Boss Point Formation, at least in part, was more closely connected to open-water depositional settings than previously thought.
