Eldredgeops is a genus of phacopid trilobites known chiefly from Middle Devonian rocks in eastern and central North America. Like related phacopids, it had large schizochroal compound eyes, a strongly vaulted exoskeleton, and the ability to enroll for protection. The genus was named for paleontologi...
Drotops is a genus of phacopid trilobites from Devonian marine rocks of what is now Morocco. Specimens are recognized by a broad cephalon, a strongly segmented thorax, prominent compound eyes of the schizochroal type, and an ability to enroll for protection. Some species attained comparatively large...
Phacops rana is an iconic Devonian trilobite found primarily in eastern North America. Its exceptionally large, compound eyes are notable for their detailed structure and played a key role in paleontological research. The species was extensively studied by Niles Eldredge, contributing to the develop...
Hollardops is a genus of phacopid trilobites known from Devonian marine rocks in Morocco, particularly deposits exposed in the Anti-Atlas region. Like other phacopids, it possessed prominent schizochroal compound eyes in which relatively large lenses were individually separated. Complete specimens a...
Calymene blumenbachi represents an iconic Silurian trilobite discovered primarily in European deposits dating back to the Early Paleozoic Era. This enrolled phacopida species is notable for being among the earliest trilobites meticulously documented by scientists. Its well-preserved fossil remains p...
Metacanthina is a genus of phacopid trilobites known from Devonian marine deposits in Morocco. Fossils assigned to the genus typically have a strongly inflated central glabellar region, prominent schizochroal compound eyes, and a body capable of enrollment. Prepared specimens are widely sold to foss...
Greenops is a genus of phacopid trilobites known from Devonian marine rocks in North America. Fossils assigned to the genus have a segmented exoskeleton, prominent eyes, and spines extending from parts of the thorax and pygidium, while articulated specimens can preserve the enrolled defensive postur...
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...
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...
Ordovician to Silurian illaenid trilobite characterized by a smooth, highly convex exoskeleton with greatly reduced segmental surface definition.
A proetid trilobite genus spanning the Late Devonian into the Carboniferous, representing one of the longer-persisting trilobite lineages documented in the stratigraphic record.
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...
A Devonian phacopid trilobite from eastern North America, studied in biogeographic analyses comparing Appalachian and Old World trilobite faunas during the Devonian.
A Devonian trilobite from South America named after German-Argentine naturalist Hermann Burmeister (1807–1892), who conducted influential paleontological surveys in Argentina.
A Carboniferous proetid trilobite widespread across Europe and North America, one of the few trilobite genera to persist well into the late Paleozoic era.
An Ordovician-Silurian calymenid trilobite abundant in South America and North Africa, commonly found in the enrolled position in Bolivian and Argentine strata.
A Carboniferous proetid trilobite known primarily from Europe, part of the late-surviving proetid lineage that persisted through much of the Carboniferous Period.
A Silurian calymenid trilobite found in Europe and North America, distinguished by its robust, heavily calcified glabella and commonly preserved in enrolled posture.
An Ordovician trilobite common in Gondwanan shallow-water facies, with fossils found across Wales, Iberia, and North Africa, used as a Lower Ordovician index fossil.
Placoparia is an Ordovician trilobite genus from Europe, distinguished by its prominent eyes and relatively large, wide cephalon.
A trilobite genus from Devonian strata of Europe, with the name referencing Belgium where Rhenish-Bohemian trilobite faunas have been extensively documented and studied.
A Devonian proetid trilobite with a compact, smooth exoskeleton, known from Paleozoic marine deposits and representing an element of the long-lived Proetida order.
A Silurian calymenid trilobite widespread across North America and Europe, frequently preserved enrolled into a tight defensive ball in Silurian carbonate deposits.
A Paleozoic calymenid trilobite genus named in honor of the paleontologist Reed, recognized by the characteristic lobed glabella typical of calymenid trilobites.
A Carboniferous to Permian trilobite, Ditomopyge is among the last surviving trilobite genera before the end-Permian mass extinction event.
