Nevadella is a genus of olenellid trilobites from the Early Cambrian of western North America. Fossils assigned to the genus are used in regional biostratigraphy because their occurrence helps paleontologists correlate rock layers of similar age. Like other olenellids, Nevadella had a broad cephalon...

Schmidtiellus is a genus of trilobites known from Lower Cambrian rocks in Estonia and Scandinavia. It belongs to an early phase of trilobite history on the paleocontinent Baltica, and its fossils are used in comparing and dating Cambrian sedimentary sequences in the region. The animal had the segmen...

Paradoxides davidis is a species of large trilobite that lived during the Middle Cambrian period, with fossils primarily found in Wales. It is recognized as one of the earliest trilobite species to be formally described from the British Isles, contributing significantly to early paleontological stud...

Serrodiscus is an extinct genus of small trilobites from the Early Cambrian, known from fossil material found in North America and Europe. It belongs to an early group of these marine arthropods and is recognized through features of its segmented dorsal exoskeleton, including a relatively small body...

Daguinaspis is a genus of early trilobites known from Lower Cambrian rocks in Morocco. It belongs to an archaic group of redlichiid trilobites and is important to paleontologists studying the earliest well-documented diversification of animals with mineralized skeletons. Its fossils contribute evide...

Paradoxides is an extinct genus of large trilobites belonging to the order Redlichiida, existing during the Middle Cambrian period. Serving as a crucial biostratigraphic index fossil, its widespread remains help geologists date marine sedimentary rocks globally. Specimens of this genus are among the...

Early Cambrian trilobite known from Gondwanan localities including Spain and Morocco, characterized by its distinctly ornamented dorsal exoskeleton.

Acadoparadoxides is an extinct genus of large trilobites belonging to the family Paradoxididae, existing during the Middle Cambrian period. As part of the Acado-Atlantic faunal province, its fossil remains are predominantly found in regions such as Morocco and the Iberian Peninsula. The genus is not...

Redlichia is an Early Cambrian trilobite genus recorded from Australia and Asia and assigned to the redlichiid trilobites. It is used as an index fossil for lower Cambrian deposits, so its occurrence can help correlate rocks from this part of the geological record. The genus is also associated with...

Eoredlichia is an extinct genus of redlichiid trilobites from the Early Cambrian. It is especially well documented in the Chengjiang biota of Yunnan, China, where articulated specimens preserve appendages, including antennae and biramous limbs; the genus is also reported from other regions, includin...

Fallotaspis is an extinct genus of redlichiid trilobites from the Early Cambrian. Fossils are known from Morocco and North America, and the genus is part of the early record of trilobite diversification soon after trilobites appear in Cambrian rocks. Its redlichiid anatomy, including a segmented tho...

Eccaparadoxides is a genus of paradoxidid trilobites from the Cambrian Period. Its fossils are associated with peri-Gondwanan regions, including parts of Iberia and other terranes that were once near the northern margin of Gondwana. The genus is closely related to Paradoxides and is recognized in st...

Protolenus is a genus of redlichiid trilobites from the early Cambrian Period. Fossils are known from Morocco and the Iberian Peninsula, regions that formed part of the peri-Gondwanan paleogeographic realm. The genus is related to early paradoxidid-grade trilobites and occurs in strata used for regi...

Callavia is a genus of olenellid trilobites from the early Cambrian Period. It is especially associated with Newfoundland, Canada, and other parts of Laurentia. The genus gives its name to the Callavia Biozone, a biostratigraphic interval used in correlating lower Cambrian rocks in the region. Calla...

Bathynotus is a genus of early trilobites from the Cambrian Period. Fossils are known from South China and from rocks assigned to very early Cambrian intervals. The genus is commonly discussed in studies of the early record of trilobites because its fossils occur near the beginning of the group’s kn...

Hydrocephalus is a genus of Cambrian trilobites described by Joachim Barrande in 1852. It is associated with the Barrandian region of what is now the Czech Republic and is placed among paradoxidid trilobites in the order Redlichiida. The name reflects the notably enlarged or inflated glabella seen i...

Mesonacis is a genus of Early Cambrian olenellid trilobites known from North America and Greenland. It belongs to the order Redlichiida and the family Olenellidae, a group associated with some of the earliest widespread trilobite faunas. Mesonacis is characterized in descriptions by the structure of...

Yunnanocephalus is a genus of trilobites from the Cambrian Period. Fossils assigned to the genus are associated with Cambrian strata in Yunnan Province and other parts of South China. It belongs to Redlichiida, one of the major early trilobite orders, and is placed in the family Yunnanocephalidae. A...

Bergeroniellus is an extinct early Cambrian trilobite genus known especially from the Siberian Platform.
