Abstract

Carboniferous (Namurian-Westphalian A) strata of the Mabou and Cumberland groups outcrop extensively in western Cape Breton Island. As well as a diverse collection of burrows, trails, pits, and coprolites described previously, numerous surface marks, mostly trackways, were encountered in these strata: Diplichnites cf. logananus (Marsh), Diplichnites isp. (types A and B), Gluckstadtella eooperi Savage, Hexapodichnus horrens Hitchcock, Monomorphichnus cf. lineatus Crimes et al., Protichnites cf. carbonarius Dawson, Protichnites cf. ketmediea (Smith), Protichnites cf. scoticus. Salter, Protichnites cf. variabilis (Linck), Protichnites isp. (types A, B, C, and D), Stiallia cf. pilosa Smith, Appendage Marks (types A and B), an "Arthropod Resting" Trace, Horn-shaped Surface Traces, and Vertebrate Trackways (types A, B, C, D, E, and F). RÉSUMÉ Des strates du Carbonifere (Namurien-Westphalien A) des groupes de Mabou et de Cumberland affleurent sur une surface étendue dans l'ouest de l'tle du Cap-Breton. On relève en outre dans ces strates une collection diversifiée de terriers, de pistes, de trous et de coprolites décrits antérieurement; un grand nombre de marques au sol, en majeure partie des pistes, comme celles du Diplichnites cf. logananus (Marsh), du Diplichnites isp. (types A et B), du Gluckstadtella eooperi Savage, de l'Hexapodichnus horrens Hitchcock, du Monomorphichnus cf. lineatus Crimes et colll, du Protichnites cf. carbonarius Dawson, du Protichnites cf. kennediea (Smith), du Protichnites cf. scoticus Salter, du Protichnites cf. variabilis (Linck), du Protichnites isp. (types A, B, C et D) et de la Stiallia cf. pilosa Smith, des marques d'appendices (types A et B), une trace "d'arthropode au repos", des traces en surface en forme de corne et des pistes de vertebres (types A, B, C, D, E, et F).
