Abstract

The ichnospecies Phycodes templus Han and Pickerill, 1994, previously only reported from the Lower Devonian Wapske Formation (Tobique Group) of New Brunswick, is described from the Lower Devonian Chapman Sandstone (Dockcndorff Group) of northeastern Maine. This recording extends the environmental range of the ichnospecies from deep-water basinal turbiditic strata of the Wapske Formation to storm-dominated shelf deposits of the Chapman Sandstone. Morphologically, Phycodes templus closely resembles the ichnotaxon Yangziichnus yichangensis Yang, 1984. Herein we recommend abandonment of the ichnogenus Yangziichnus and suggest assignment to Phycodes, namely Phycodes yichangensis comb. nov. RÉSUMÉ L'ichnoespèce Phycodes templus de Han et Pickerill, 1994, antérieurcment seulement signalée a partir de la formation du Dévonien inférieur Wapske (groupe de Tobique) au Nouveau-Brunswick, a élé replrée dans le secteur du Dévonien inferieur de Chapman Sandstone (groupe de Dockendorff) dans le nord-est du Maine. Ce relevé étend le territoire environnemental des ichnoespèces des strates turbiditiques de bassins marins profonds de la formation Wapske aux dépôts de la plate-forme dominée par les tempétes du secteur de Chapman Sandstone. D'un point de vue morphologique, le Phycodes templus ressemble beaucoup à l'ichnotaxon Yangziichnus yichangensis de Yang, 1984. Nous recommandons par les présentes l'abandon de l'ichnogenre Yangziichnus et nous proposons sa classification parmi les Phycodes, notamment à titre de nouvelle combinaison Phycodes yichangensis.
