A review of Salterella (Phylum Agmata) from the Lower Cambrian in Greenland and Mexico

Records of SalterelIa from the Lower Cambrian in Greenland are reviewed and all specimens are referred to S. maccullochi (Murchison, 1859). Examples are iIIustrated for the first time from the Brønlund Fjord Group of Peary Land, central North Greenland and from the Hyolithus Creek Formation at Kap Weber and at C. H. Ostenfeld Nunatak, northern East Greenland. S. mexicana Lochman in Cooper et al., 1952, from Sonora, Mexico, is iIIustrated in thin sections and is placed into synonymy with S. maccullochi.
