Résumé

Phycodes templus isp. nov. is described from siliciclastic turbidites of the Wapske Formation of the Tobique Group (Lower Devonian) of northwestern New Brunswick, eastern Canada. The new ichnospecies is characterized by a minimum of two, more typically several, bundled sets of essentially horizontal, broomlike or flabellate, internally structureless, lined burrows. Burrow sets within an individual specimen are interconnected by a single tunnel to form an overall inverted pagoda-shaped structure. The ichnotaxon is believed to have been produced by a vagile deposit feeder, most likely a worm-like organism. RÉSUMÉ Phycodes templus isp. nov. est décrit à partir d'échantillons provenant de turbidites siliciclastiqucs de la Formation de Wapske du Groupe de Tobique (Dévonien inférieur) du nord-ouest du Nouveau-Brunswick, dans L'Est du Canada. La nouvelle espèce d'ichnofossile est caractérisée par un minimum de deux, plus typiquement plusieurs ensembles groupés de terriers doublés, essentiellement horizontaux, en forme de balai ou d'éventail et sans structures internes. Les ensembles de terriers dans un spécimen donné sont interconnectés par un tunnel simple pour former une structure d'ensemble en forme de pagode inversée. On croit que L'ichnofossile a été produit par un animal mobile se nourissant de dépôts et ressemblant probablement à un ver. [Traduit par la rédaction]
