Arcticalymene is a genus of trilobites found in Silurian-aged marine strata of Arctic Canada and Central Victoria, Australia. The Canadian species are named after each of the Sex Pistols: A. cooki, A. jonesi, A. matlocki, A. rotteni and A. viciousi, all named by Adrain and Edgecombe in 1997.
Bumastus is an extinct genus of corynexochid trilobites which existed from the Early Ordovician period to the Late Silurian period. 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.

Aponileus is an extinct genus of trilobites. Chung-Hung Hu circumscribed the genus in 1963. The genus was once considered a junior subjective synonym of the genus Psephosthenaspis but it is considered to be a distinct genus again.
