A Carboniferous proetid trilobite widespread across Europe and North America, one of the few trilobite genera to persist well into the late Paleozoic era.
A Carboniferous proetid trilobite known from Mississippian limestones of Europe and North America, found in association with coal-measure-adjacent carbonate facies.
Devonian proetid trilobite from European and North African strata, noted for prominent tubercles covering the glabella and fixigenae, giving it a distinctively knobbed dorsal surface.
A Permian trilobite from Tethyan marine deposits, Pseudophillipsia is among the last surviving trilobite genera before the end-Permian extinction.
A Carboniferous proetid trilobite known primarily from Europe, part of the late-surviving proetid lineage that persisted through much of the Carboniferous Period.
A Devonian proetid trilobite with a long stratigraphic range and wide geographic distribution across Europe and North America, belonging to one of the last surviving trilobite lineages.
A Carboniferous proetid trilobite from Europe and North America, known from Mississippian and Pennsylvanian strata and notable for its compact form and smooth glabella.
A Devonian proetid trilobite from Europe named in honor of the German geologist Heinrich von Dechen, known from Middle Devonian carbonate facies of the Rhenish region.
A Carboniferous to Permian trilobite, Ditomopyge is among the last surviving trilobite genera before the end-Permian mass extinction event.
Archaeogonus is a Carboniferous proetid trilobite from Europe, one of several proetid genera that persisted into the late Paleozoic era.
Small Silurian to Devonian proetid trilobite from European localities, notable for its compact, smooth exoskeleton and broad stratigraphic and geographic distribution.
An Ordovician trinucleoid trilobite genus from Europe, particularly Bohemia, characterized by a pitted cephalic fringe typical of the family Trinucleidae.
A Cambrian trilobite genus representing a primitive form within its taxonomic group, known from early Paleozoic deposits and contributing to phylogenetic studies of early trilobites.
A Middle Cambrian trilobite genus of the order Ptychopariida, known from deposits in multiple regions and recognized by its distinctive cranidial and pygidial morphology.
