Terataspis grandis is a species of lichid trilobite from Devonian rocks in what is now New York State. It is known primarily from incomplete remains, including unusually large portions of the exoskeleton, so estimates of its full body length are necessarily uncertain. Reconstructions based on those...
Terataspis is a genus of lichid trilobite known from Devonian rocks in North America, especially from incomplete exoskeletal remains. Like other lichids, it possessed a strongly ornamented calcified exoskeleton, with prominent spines extending from parts of the head, thorax, and tail shield. Reconst...
Uralichas is a genus of large lichid trilobites known from Ordovician rocks of the Iberian Peninsula and nearby regions. Some attributed specimens exceed 60 centimeters in length, placing the genus among the largest trilobites documented in the fossil record. Its strongly segmented exoskeleton and i...
Comura is a Devonian-era trilobite discovered in Morocco. It’s notable for its exceptionally elongated spines extending from both its thorax and tail shield, characteristics defining its Lichida family lineage. These unique features make Comura specimens highly sought after by paleontologists and fo...
Kolihapeltis represents a large trilobite species from the Devonian period discovered in Moroccan shale deposits. This fossil is notable for its exceptionally long genal spines and elongated occipital spine—unique features within the Lichida family of trilobites. Paleontologists study Kolihapeltis t...
Arctinurus is an extinct genus of large trilobites that lived during the Silurian period, primarily discovered in the Rochester Shale deposits of New York State. The genus is easily recognized by its broad, heavy exoskeleton and distinctive stellate, or star-like, outline when viewed from above. Pal...
Ceratarges is an extinct genus of lichid trilobites that lived during the Devonian period, with fossils commonly found in Europe and North Africa, particularly Morocco. It is recognized among paleontologists and collectors for its highly elaborate, multi-pronged spines extending from its cephalon an...
Radiaspis is an extinct genus of lichid trilobites that lived during the Devonian period. Fossils of this marine arthropod are commonly recovered from ancient reef deposits in Morocco, where they are often preserved in limestone. The genus is distinguished by an elaborate, ornate exoskeleton featuri...
Acanthopyge is an extinct genus of spiny lichid trilobite that lived primarily during the Devonian period. It is easily distinguished from other trilobites by its highly elaborate, heavily spinosed exoskeleton, featuring prominent spines along the thoracic segments and the marginal cephalon. Paleont...
Thysanopeltis is an extinct genus of trilobite within the order Lichida that lived during the Middle Devonian period. It is characterized by its highly ornate exoskeleton, specifically its broad, fringed pygidial border featuring distinct marginal spines. Fossils of this marine arthropod are commonl...
