Bumastus barriensis, from the Silurian Wenlock series, found at Dudley, Worcestershire.
Bumastus is an extinct genus of corynexochid trilobites which existed from the Early Ordovician period to the Late Silurian period.[1] They were relatively large trilobites, reaching a length of 6 in (15 cm). 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 and South America, Europe, Asia, and Australia. They are classified under the family Styginidae in the order Corynexochida.[2]
