Setolebia
Setolebia is a genus of extinct trilobites belonging to the order Asaphida. Fossils of Setolebia have been found in deposits dating back to the Ordovician period, specifically in regions of Russia. These trilobites are characterized by their distinctive cephalon (head shield), thorax (segmented mid-section), and pygidium (tail shield). The morphology of Setolebia suggests it was a benthic organism, likely residing on or near the seafloor. Further research on Setolebia contributes to our understanding of trilobite evolution and the paleogeography of the Ordovician period. Its taxonomic classification is subject to ongoing revision based on new fossil discoveries and phylogenetic analyses. The genus is of interest to paleontologists studying the biodiversity and paleoecology of ancient marine ecosystems.
