''Bumastus'' is an extinct genus of Corynexochida, corynexochid trilobites which existed from the Early Ordovician Period (geology), period to the Late Silurian period. They were relatively large trilobites, reaching a length of . They were distinctive for their highly globular, smooth-surfaced exoskeleton. They possessed well-developed, large compound eyes and were believed to have dwelled in shallow-water sediments in life. ''Bumastus'' fossils have been found in North America, North and South America, Europe, Asia, and Australia. They are classified under the Family (biology), family Styginidae in the Order (biology), order Corynexochida. Description ''Bumastus'' is a large trilobite, reaching a length of . The body is oblong-oval, about twice as long as it is wide, It had a strongly convex profile, giving it its distinctive globular appearance. Like all trilobites, the body is divided into three functional segments known as Tagma (biology), tagmata (singular: tagma), which ...
