Frammia is a genus of trilobites in the order Phacopida that existed during the middle and upper Silurian in what is now the Arctic regions of Canada and Russia . It was described by Holtedahl in 1914, and the type species is Frammia dissimilis. That species was subsequently considered to be a synonym of Frammia arctica (Salter, 1852).[1] The genus also contains the species, F. bachae Adrain & Edgecombe, 1997, F. hyperborea (Thomas, 1979), and F. rossica (Maksimova, 1970). The type locality is the Douro Formation of Cornwallis Island in Nunavut, Canadian Arctic.[2]
