description Brachymetopus Overview
Brachymetopus is an extinct genus of proetid trilobites known from Carboniferous rocks in Europe and North America. It occurs in both Mississippian and Pennsylvanian strata, placing it within a period when trilobite diversity had declined from its earlier Paleozoic levels. The genus is characterized by a compact body and a relatively smooth glabella, and it is relevant to studies of late trilobite evolution.
help Brachymetopus FAQ
When did Brachymetopus live?
Brachymetopus lived during the Carboniferous Period. It occurs in both Mississippian and Pennsylvanian strata.
What family does Brachymetopus belong to?
Brachymetopus is a proetid trilobite. Proetids were among the trilobite groups that survived into the Carboniferous after many earlier lineages disappeared.
Where have Brachymetopus fossils been found?
Fossils are known from Carboniferous rocks in Europe and North America. Their presence on both sides of the ancient Atlantic reflects the wider distribution of Carboniferous marine faunas.
Why is Brachymetopus notable among trilobites?
It lived late in trilobite history, when overall diversity had already declined from earlier Paleozoic levels. Its Mississippian and Pennsylvanian record shows that proetids remained present near the end of the group’s history.
