Scutellum is a genus of extinct trilobites known from Devonian marine deposits, particularly those of present-day Europe. It belongs to a group characterized by a comparatively broad, shield-shaped pygidium, the posterior section of a trilobite's exoskeleton. Fossils assigned to the genus are of int...

Jaekelopterus rhenaniae is a giant eurypterid, an extinct aquatic chelicerate commonly called a sea scorpion, from Early Devonian deposits in Germany. A fossilized claw fragment has been used to estimate a total body length of roughly 2.5 meters, placing it among the largest arthropods known. Its ro...

Devonian odontopleurid trilobite notable for horn-like forward projections on its glabella, known from Devonian strata of Europe and North Africa.

Phacops is a Devonian trilobite species originating from North America. It’s notable for its unique schizochroal eyes, complex structures that could move independently to track movement. These eyes provided crucial evidence supporting Niles Eldredge's theory of punctuated equilibrium in the 1970s. T...

Wattieza was a tree-sized cladoxylopsid plant that lived during the Middle Devonian, roughly 385 million years ago. Fossil trunks historically called Eospermatopteris were discovered at Gilboa, New York, while later crown material allowed researchers to reconstruct the plant as a tall trunk topped b...

Clearwater Lake West is a circular lake occupying an impact structure in northern Quebec, Canada. It lies beside Clearwater Lake East, and the neighboring forms were long described as a paired impact feature, although later dating indicated that they did not form simultaneously. The western structur...

Metacanthina is a genus of phacopid trilobites known from Devonian marine deposits in Morocco. Fossils assigned to the genus typically have a strongly inflated central glabellar region, prominent schizochroal compound eyes, and a body capable of enrollment. Prepared specimens are widely sold to foss...

Greenops is a genus of phacopid trilobites known from Devonian marine rocks in North America. Fossils assigned to the genus have a segmented exoskeleton, prominent eyes, and spines extending from parts of the thorax and pygidium, while articulated specimens can preserve the enrolled defensive postur...

A Devonian proetid trilobite from Morocco named for the prominent horn-like glabellar projections, commonly collected from Devonian limestone in the Anti-Atlas region.

Barrandeops is a genus of phacopid trilobites known from Devonian marine deposits, particularly specimens collected in Morocco. Like other phacopids, it possessed large schizochroal compound eyes made from relatively few, individually separated lenses, along with a strongly developed central area of...

Meemann Chang is a Chinese paleontologist associated with the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing. She is recognized for her extensive research on extinct fossil fishes, particularly sarcopterygians and their evolutionary relationship to early tetrapods. Chan...

Kettneraspis is an extinct genus of spiny odontopleurid trilobite that existed during the Devonian period. It is distinguished by an elaborately ornamented exoskeleton, featuring elongated, sweeping marginal spines that line both the cephalon and the pygidium. Fossils of this genus are commonly unco...
