SYSTEMATIC ICHNOLOGY OF THE MABOU AND CUMBERLAND GROUPS (CARBONIFEROUS) OF WESTERN CAPE-BRETON ISLAND, EASTERN CANADA, 1 - BURROWS, PITS, TRAILS, AND COPROLITES

Strata of the Mabou and Cumberland groups (Namurian-Westphalian A) out crop extensively in western Cape Breton Island. Trace fossils were enc ountered at various localities, and include: Circulichnus montanus (no m. correct.), Cochlichnus anguineus, Cochlichnus isp., Conichnus isp., Cruziana problematica, Didymaulichnus cf. lyelli, Diplopodichnus bifo rmis, Gordia marina, Helminthopsis abeli, Helminthopsis hieroglyphica, Palaeophycus striatus, cf. Palaeophycus, Phycodes pedum, Planolites b everleyensis, Planolites terraenovae, cf. Planolites, Rusophycus carbo narius, cf. Rusophycus, Selenichnites isp., Taenidium barretti, cf. Ta enidium, Thalassinoides suevicus, Undichnus binus (nom. correct.), Und ichnus consulcus (nom. correct.), cf. Undichnus, coprolites, interface trails (types A, B, and C), plug-shaped burrows, small ovate pits (ty pes A, B, and C), and vertical 'escape' structures. In total (includin g tracks and trackways not described herein), twenty-two ichnogenera h ave been identified that comprise a total of eighteen named ichnospeci es, eight ichnospecies retained in open nomenclature, and thirteen unn amed ichnospecies. A further ten trace-fossil morphologies (comprising twenty different types) are retained in the vernacular.
