Kitab Geological National Nature Park in Azerbaijan preserves unique exposures of Middle Eocene sedimentary rocks showcasing fossilized plants and marine organisms, vital for understanding regional geological history.

Reedops is an extinct genus of phacopid trilobite known from Devonian marine rocks. Fossil studies of species such as Reedops cephalotes, Reedops sternbergi, and Reedops bronni document schizochroal eyes, a phacopid visual structure made from separate lens units set into the eye surface. The genus i...

Viaphacops is a genus of phacopid trilobites known from Devonian rocks in eastern North America. It belongs to Phacopida, an order of extinct marine arthropods whose members had calcified exoskeletons and could enroll their bodies for protection. Fossils assigned to Viaphacops are used in studies of...

Morocops is an extinct genus of phacopid trilobites known from Devonian rocks in Morocco, including the Anti-Atlas region. It belongs to Phacopidae, a family of trilobites recognized for compound eyes built from many large visual lenses and for a distinct cephalon, thorax, and pygidium. Morocops is...

Burmeisterella is a genus of trilobites known from Devonian fossil deposits in South America. Its name commemorates Hermann Burmeister, a German-Argentine naturalist who studied the natural history and fossils of Argentina. As an extinct arthropod, it is represented by mineralized exoskeletal remain...

Cyphaspides is a genus of extinct aulacopleurid trilobites known from Devonian marine rocks. Paleontological studies have described species from southeastern Morocco, while published comparisons also include material from China and Germany, reflecting the genus's use in research on Devonian trilobit...

Reedops cephalotes is a Devonian phacopid trilobite known from Czech and other European strata. Its morphology includes a proportionally large cephalon, well-developed schizochroal eyes, and a comparatively smooth glabella. These features place it among phacopid trilobites whose visual surfaces are...

Huntonia is a Devonian phacopid trilobite genus associated with Oklahoma and surrounding parts of North America. It is recognized by a smoothly inflated glabella and large schizochroal eyes, features that help distinguish it within mid-Devonian phacopid material. The genus is also placed among aster...

Pedinopariops is a Devonian phacopid trilobite genus reported from Morocco and Europe. It is closely related to Phacops, but its identification depends in part on the number and arrangement of lenses in the schizochroal eye surface. That eye structure provides a useful comparative character in phaco...

Geesops is a Devonian phacopid trilobite genus known from Europe and Morocco. It has prominent schizochroal eyes and a strongly convex glabella, giving the cephalon a robust profile characteristic of many phacopid forms. Geesops occurs in Devonian fossil assemblages that include reef-associated envi...

Asteropyge is a Devonian trilobite genus in the asteropygid group of the order Phacopida.
