Best Corynexochida

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...

A Devonian scutelluoid trilobite related to Scutellum, known from European Devonian deposits and distinguished by its ribbed, broadly expanded pygidium.

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...

Ordovician asaphid trilobite from Baltica, known from Scandinavian limestones and notable for its elongated body form relative to other members of Asaphida.

Middle Cambrian trilobite whose species O. indicus defines a globally recognized biozone used to correlate Cambrian stratigraphy across multiple continents.

Arthricocephalus is a Cambrian trilobite genus from South China used as an index fossil for the lower Cambrian strata of that region.

Middle Cambrian corynexochid trilobite distributed across North America and Asia, commonly found in deposits contemporaneous with the Burgess Shale fauna.

Middle Cambrian trilobite widespread across North America, serving as a key index fossil for the Bathyuriscus-Elrathina biozone in Cambrian stratigraphy.

Middle Cambrian trilobite abundant in North America that gives its name to the Glossopleura biozone, a key interval in regional Cambrian stratigraphy.

Middle Cambrian trilobite of the order Corynexochida with broad distribution across North America, Europe, and Asia during the mid-Cambrian period.

Middle Cambrian corynexochid trilobite found in North America and Asia, recognized by its distinctive elongated pygidium bearing marginal spines.

A Cambrian trilobite genus morphologically similar to Loganopeltis, known from Lower to Middle Cambrian deposits in Asia and indicative of early trilobite evolutionary radiation.

Cambrian trilobite genus known from Gondwanan terranes, contributing to understanding of early Cambrian biogeographic dispersal patterns.
