Silurian trilobites from Hall Land and Nyeboe Land, western North Greenland

Abstract

The Silurian trilobites described below are referred to 16 genera of which 1 is new (Nonix); 21 species-level taxa are recognized of which 4 are new species (Kosovopeltis allaarti, Proetus s.l. simus, Contracheirurus errator and Nonix sauroter), 3 are previously-described species and 14 are left in open nomenclature. The biostratigraphic and palaeogeographic links implied by the trilobites are discussed after each taxon, but the fauna as a whole is similar to Wenlock faunas from Arctic Canada.
