Phylum Brachiopoda Duméril, 1806

Discussion.—Five species of brachiopods occur in the acid residues from the Forteau Formation of western Newfoundland. No detailed description of the material is given herein, but linguliforms are represented by Eoobolus priscus ( Poulsen, 1932) ( Fig. 2A, B ), one unidentified eothelid ( Fig. 2C ) and one acrotretid species ( Fig. 2D, E ) as well as the pateriniid Micromitra bella (Billings, 1872) ( Fig. 2F, G ). Rhynchonelliforms are represented by Obolella crassa (Hall, 1847) ( Fig. 2H, I ). Three of the species, E. priscus , M. bella , and O. crassa are also found in the Taconic allochthons and in the Bastion Formation of North−East Greenland (see review in Skovsted and Holmer 2005). Eothelids and acrotretids are common in the Cambrian of Laurentia, although their taxonomy is best known from the western part of the continent ( Rowell 1980; Voronova et al. 1987; Streng and Holmer 2006).
