Article copyright remains with the publisher, society or author(s) as specified within the article. The Mistaken Point assemblage of the Ediacara fossils is dominated by rangeomorphs with homologous fractal branching elements. The most distinctive are the fusiform fossils, herein named Fractofusus misrai n.gen., and n.sp., and Fractofusus andersoni n.gen., and n.sp. Although endemic to the Newfoundland portion of the Avalonia terrane, they dominated deep sea-floor communities below the photic zone, in the mid-Ediacaran Period (ca. 575-560 Ma). Their biological affinities remain uncertain, but their architecture suggests a phylogenetic position near the base of the Metazoa. L'assemblage de fossiles édiacariens de Mistaken Point est dominé par des rangeomorphes présentant des éléments homologues à embranchement fractal. Les plus distinctifs sont des fossiles fusiformes ici nommés Fractofusus misrai n.gen. et n.sp. et Fractofusus andersoni n.gen. et n.sp. Bien qu'ils soient endémiques à la portion terre-neuvienne du terrane d'Avalon, ils dominaient de communautés du fond marin profond sous la zone photique durant la période édiacarienne moyenne (v. 575-560 Ma). Leurs affinités biologiques demeurent incertaines, mais leur architecture laisse croire à une position phylogénétique près de la base des Métazoaires.
