Barrandeops is a genus of phacopid trilobites known from Devonian marine deposits, particularly specimens collected in Morocco. Like other phacopids, it possessed large schizochroal compound eyes made from relatively few, individually separated lenses, along with a strongly developed central area of...

Eophacops is an extinct genus of trilobites belonging to the Phacopidae family, primarily existing during the Early Devonian period. Fossils of this marine arthropod are commonly found in Lower Devonian strata across regions including Europe and North Africa. Like other phacopids, it possessed large...

Calymene is a genus of trilobites that lived primarily during the Silurian period, with fossils commonly found across Europe and North America. As a member of the order Phacopida, these arthropods are recognized for their well-preserved enrolled fossils. The species Calymene blumenbachii, nicknamed...

Bumastoides is an extinct genus of illaenid trilobite that existed during the Ordovician and Silurian periods. It is characterized by its smooth, highly convex exoskeleton that displays greatly reduced surface definition between its body segments. The genus features a large, rounded head shield (cep...

Archegonus is an extinct genus of trilobites belonging to the order Proetida, a group of marine arthropods that survived long after many other trilobite lineages died out. Fossils of this genus are primarily found in Europe and North America, with specimens dating to the Carboniferous period. Like o...

A Devonian trilobite of the Malvinokaffric Province, known from South American localities in Brazil and Bolivia, characteristic of cold-water Gondwanan shelf faunas.

Flexicalymene is an extinct genus of trilobites that existed during the Ordovician period. These arthropods are commonly found in the limestones of the Cincinnati region in Ohio, USA, as well as in parts of Europe. Flexicalymene trilobites are frequently discovered in an enrolled state, rolled into...

Viaphacops is a genus of phacopid trilobites known from Devonian rocks in eastern North America. It belongs to Phacopida, an order of extinct marine arthropods whose members had calcified exoskeletons and could enroll their bodies for protection. Fossils assigned to Viaphacops are used in studies of...

Burmeisterella is a genus of trilobites known from Devonian fossil deposits in South America. Its name commemorates Hermann Burmeister, a German-Argentine naturalist who studied the natural history and fossils of Argentina. As an extinct arthropod, it is represented by mineralized exoskeletal remain...

Phillipsia is a Carboniferous proetid trilobite genus recorded from Europe and North America. It is notable because trilobites of the genus Phillipsia survived into the late Paleozoic, when trilobite diversity had already declined substantially compared with earlier periods. Its compact body and cap...

An Ordovician-Silurian calymenid trilobite abundant in South America and North Africa, commonly found in the enrolled position in Bolivian and Argentine strata.

Paladin is a genus of phillipsiid trilobites from the Carboniferous Period. Its fossils are known from marine strata in Europe and from other regions represented in the phillipsiid record.
