Acanthostega gunnari was a Late Devonian stem tetrapod known from fossils found in East Greenland. It possessed limbs with eight digits, but its limb proportions, tail fin, and internal gills indicate that it remained primarily aquatic rather than moving effectively on land. The animal provides impo...

Ichthyostega stensioei was a Late Devonian vertebrate from East Greenland and one of the earliest well-known tetrapods. It combined limbs with digits and a strong ribcage with aquatic features, including a finned tail and sensory adaptations inherited from fishlike ancestors. Its anatomy indicates t...

Eldredgeops is a genus of phacopid trilobites known chiefly from Middle Devonian rocks in eastern and central North America. Like related phacopids, it had large schizochroal compound eyes, a strongly vaulted exoskeleton, and the ability to enroll for protection. The genus was named for paleontologi...

Drotops megalomanicus is a large phacopid trilobite from Lower Devonian marine deposits in Morocco. It is distinguished by a broad, strongly vaulted exoskeleton, prominent compound eyes, and a surface covered with conspicuous tubercles. Complete specimens can reach roughly 15 centimeters or more, ma...

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...

Dunkleosteus terrelli was a large predatory placoderm fish that lived during the Late Devonian Period and is known especially from fossils found in Ohio. Its head and forward trunk were protected by articulated bony plates, while sharpened edges on its jaw plates functioned as cutting surfaces inste...

Walliserops trifurcatus is a Devonian trilobite discovered in Morocco. This iconic fossil is notable for its exceptionally long, three-pronged rostral spine—a feature characteristic of the odontopleuride group. Its complex cranial structure provides valuable insight into trilobite evolution and is p...

Erbenochile is a Devonian trilobite discovered in Morocco. This fossil is notable due to its exceptionally large, tower-like schizochroal eyes, which afforded it near panoramic vision. The structure represents the phacopida group and offers valuable insight into the visual capabilities of early arth...

Drotops is a genus of phacopid trilobites from Devonian marine rocks of what is now Morocco. Specimens are recognized by a broad cephalon, a strongly segmented thorax, prominent compound eyes of the schizochroal type, and an ability to enroll for protection. Some species attained comparatively large...

Erbenochile erbeni is a Devonian-era trilobite discovered in Morocco. It’s notable for possessing exceptionally large, hypertrophied eyes—the tallest “tower-eyes” and widest visual field among known phacopids. This fossil offers insights into the evolution of complex vision in ancient marine inverte...

The Walliserops is a remarkable Devonian trilobite fossil discovered in Morocco. It’s notable for its exceptionally long, trident-like spine projecting from its head shield. Belonging to the odontopleurida group, this specimen provides valuable insight into the evolution and diversity of early arthr...

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...
