<i>Onuphionella corusca</i> sp. nov.: an early Cambrian-type agglutinated tube from Upper Ordovician strata of Morocco

A variety of unrelated organisms produce agglutinated tubes as dwelling structures, and the habit has persisted since the Neoproterozoic. <i>Onuphionella</i>, an agglutinated tube composed of mica flakes, has been found in lower Cambrian strata on several palaeocontinents. In this paper, a new species of the genus, <i>Onuphionella corusca</i> sp. nov., is described from the Sandbian (Upper Ordovician) First Bani Group of the Erfoud region, Morocco. The First Bani Group was formed in a storm-dominated shelf environment below fair-weather wave base. The agglutinated tubes are found in abundance on numerous bedding surfaces, possibly representing repeated colonization between storm events, and the tube maker must have been a major part of the local ecosystem. This is the first report of <i>Onuphionella</i> from Ordovician rocks and the first from Gondwana.
