Richterops
''Richterops'' is an extinct genus of trilobite arthropods. The genus lived during the middle of the Atdabanian or the early part of the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the second half of the Lower Cambrian. It has been found in southern Morocco. It can be recognised by the long spines of the headshield that are a smooth continuation of the frontal edge, and the enlarged spines on the 11th segment of the thorax. == Distribution == Lower Cambrian of Southern Morocco (''Daguinaspis'' and ''Resserops''-zone near Tazemmourt,〔 Amouslek and Ouijane).
