Genus Productus Sowerby, 1814 View in CoL
Type species: Conchyliolithus Anomites ( productus ) Martin, 1809, from the upper Visean of Derbyshire, England.
Remarks.—The genus can be distinguished from others in the Productidae in having a straight, laterally spreading trail, a suboval rather than subquadrate corpus outline and in the absence of a ventral sulcus. Most species are characterised also by having spines arranged only in 2–3 rows on ears and scattered on visceral disc, and by the presence of a dorsal diaphragm.
