A Devonian trilobite distinguished by an exceptionally wide, semicircular pygidium giving the body a fan-like outline, found across Devonian deposits in Europe and North Africa.

Scutellum is a genus of extinct trilobites known from Devonian marine deposits, particularly those of present-day Europe. It belongs to a group characterized by a comparatively broad, shield-shaped pygidium, the posterior section of a trilobite's exoskeleton. Fossils assigned to the genus are of int...

Xystridura is a genus of trilobites from the Middle Cambrian rocks of Australia, particularly deposits in Queensland's Georgina Basin. Its fossils are sufficiently characteristic and geographically useful that Xystridura has been used in biostratigraphic schemes for correlating parts of the Australi...

Kootenia burgessensis is an extinct species of trilobite that existed during the Middle Cambrian period. It is primarily known from the famous Burgess Shale deposit located in the Canadian Rockies of British Columbia, Canada. The species was originally described by paleontologist Charles Doolittle W...

Torleyiscutellum is an extinct genus of scutelluoid trilobite that lived during the Devonian period. Fossil specimens of this marine arthropod have been primarily discovered in European geological deposits. The genus is closely related to Scutellum and is distinguished anatomically by its broadly ex...

Olenoides is an extinct genus of trilobites that lived during the Middle Cambrian period, widely known from fossil deposits in the Burgess Shale of British Columbia, Canada. As a corynexochid trilobite, it possessed a relatively large, semi-circular cephalon and a powerful pygidium. The Burgess Shal...

Zacanthoides is an extinct genus of corynexochid trilobite that lived during the Middle Cambrian period. Fossils of this marine arthropod are primarily found in the Burgess Shale of British Columbia and other related deposits across North America. The genus is distinguished by its heavy spination, f...

Ogygopsis is an extinct genus of trilobite from the Middle Cambrian period, belonging to the order Corynexochida. Specimens are predominantly recovered from the Burgess Shale formation in Yoho National Park, British Columbia, Canada. It is recognized as one of the most common and frequently encounte...

Dolichometopus is an extinct genus of Ordovician asaphid trilobites, known from fossil-bearing limestones associated with Baltica, including parts of Scandinavia. It is distinguished by an elongated body form relative to other members of Asaphida, the trilobite group to which it belongs. As a trilob...

Oryctocephalus is a genus of corynexochid trilobites from the Cambrian Period. It is known from several paleogeographic regions, and the species Oryctocephalus indicus is associated with a widely used Cambrian biostratigraphic interval. Fossils of the genus are important for correlating marine strat...

Arthricocephalus is a genus of trilobites that lived during the Cambrian Period. Fossils assigned to the genus are especially associated with South China, where they have been used in biostratigraphy to help identify and correlate lower Cambrian rock units. Arthricocephalus belongs to the family Ory...

Kootenia is an extinct genus of corynexochid trilobites from the Middle Cambrian. Fossils assigned to the genus are known from parts of North America and Asia, and Kootenia occurs in rocks formed during the interval associated with Burgess Shale type Cambrian faunas. Its distribution and stratigraph...

Bathyuriscus is a genus of Middle Cambrian trilobites that is widely represented in North American fossil deposits. It is placed in the family Bathyuriscidae and the order Corynexochida, a group whose members commonly had well-developed trilobite body regions and distinctive cephalic forms. The genu...

Glossopleura is a genus of Middle Cambrian trilobites known especially from North American fossil deposits. It belongs to the order Corynexochida and the family Glossopleuridae, and its fossils are used to identify the Glossopleura Biozone. That biozone provides a named interval for regional Cambria...

Corynexochus is a genus of Middle Cambrian trilobites and the type genus of the family Corynexochidae. Fossils assigned to Corynexochus are reported from several regions, including North America, Europe, and Asia, showing that related forms occupied widely separated Cambrian marine environments. The...

Dorypyge is an extinct genus of Middle Cambrian trilobites in the family Dorypygidae and the order Corynexochida. Fossils have been reported from North America and Asia. The genus is recognized by its elongated pygidium, the rear shield of the trilobite body, which bears marginal spines. Dorypyge is...

Loganopeltoides is an extinct genus of Cambrian trilobites in the family Harpididae, a group within the order Harpetida. Fossils attributed to the genus occur in Cambrian marine strata, including deposits in Kazakhstan and North America. Species such as Loganopeltoides zenkeri and Loganopeltoides pr...

Fieldaspis is an extinct genus of Cambrian corynexochid trilobites assigned to the family Fieldaspididae. Descriptions characterize it as small to moderate in size, with a gently convex cranidium, a low glabella with weak furrows, and an occipital ring that may carry a median spine. Fossils and poss...
