Eramoscorpius brucensis is a Silurian fossil scorpion from Ontario, named in 2015 and interpreted as an early semi-terrestrial form.
Palaeophonus nuncius is an extinct species of scorpion that lived during the Silurian period. Fossils of this arachnid were discovered in Sweden and described by Thorell and Lindström in 1884. As one of the oldest known scorpion genera, Palaeophonus retains primitive features. Paleontologists classi...
Calymene blumenbachii is a species of trilobite from Silurian rocks, particularly the Wenlock Limestone around Dudley in the English West Midlands. Its compact, segmented exoskeleton could roll into a defensive ball, and abundant local fossils became popularly known as the Dudley Bug or Dudley Locus...
Aulacopleura is a genus of small trilobites known especially from Silurian deposits in the Czech Republic. Large assemblages of Aulacopleura koninckii preserve individuals across many growth stages, allowing researchers to reconstruct how segments were added and body proportions changed during devel...
Dalmanites limulurus is an extinct species of trilobite from Silurian rocks in New York State, including the Rochester Shale. It belongs to Dalmanitidae, a family within the order Phacopida, and has the prominent eyes, segmented exoskeleton, and elongated terminal spine associated with its genus. It...
Deiphon represents a notable Silurian trilobite genus belonging to the Cheiruridae family. This European fossil, discovered in Bohemia, is characterized by its globose body shape and prominent spines on the glabella. It’s particularly valuable for paleontologists studying the evolution of early tril...
Brontoscorpio anglicus was a giant scorpion that lived during the Silurian period approximately 420 million years ago. Fossils discovered in England reveal it to be one of the largest known scorpions from this era. Its unique aquatic ancestry and substantial size make it an important subject for pal...
Calymene blumenbachi represents an iconic Silurian trilobite discovered primarily in European deposits dating back to the Early Paleozoic Era. This enrolled phacopida species is notable for being among the earliest trilobites meticulously documented by scientists. Its well-preserved fossil remains p...
Proscorpius osborni represents a crucial early scorpion fossil discovered in New York during the Silurian period approximately 420 million years ago. This extinct species is notable as one of the oldest known scorpion remains, offering significant insight into the evolutionary origins of scorpions a...
Roderick Murchison was a Scottish geologist renowned for his pioneering work in stratigraphy. His detailed surveys of Scotland, particularly concerning Silurian rock formations, led to the formal definition and naming of the Silurian geological period during the 1830s. This established a crucial ben...
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...
Eurypterus remipes was an aquatic arthropod, commonly called a sea scorpion, that lived during the Silurian Period. Fossils are especially abundant in rocks of New York State, where exceptionally preserved specimens reveal its segmented body, broad swimming appendages, and paddle-shaped rear limbs....
Waeringoscorpius hefteri is an extinct species of scorpion that lived during the Silurian period, approximately 443-419 million years ago. Fossil specimens have been discovered in the Bertie Group of New York state, preserving details of these early arachnids. The genus was named by paleontologist E...
Encrinurus is an extinct genus of trilobite belonging to the order Phacopida that lived during the Silurian period. Fossils of this marine arthropod are widely distributed across sedimentary deposits in North America and Europe. It is easily recognized by its heavily tuberculate exoskeleton and a di...
An Ordovician cheirurid trilobite named for its cross-shaped glabella, recorded from Baltoscandia and the British Isles across multiple Ordovician stages.
Dalmanites is an extinct genus of phacopid trilobites that existed throughout the Silurian and Early Devonian periods. Fossils of this arthropod are widespread, commonly discovered in marine sedimentary rocks across North America, Europe, and South America. It is physically recognized by its well-de...
Calymene is a genus of trilobites that lived primarily during the Silurian period, with fossils commonly found across Europe and North America. As a member of the order Phacopida, these arthropods are recognized for their well-preserved enrolled fossils. The species Calymene blumenbachii, nicknamed...
Monograptus priodon is a Silurian graptolite bearing a single stipe, widely used as an index fossil for biostratigraphic correlation of Lower Silurian strata.
Silurian to Devonian phacopid trilobite common in European marine deposits, recognized for its large schizochroal compound eyes with individually lensed facets.
A Silurian encrinurid trilobite best known from China, where C. rex serves as a significant index fossil for Silurian biostratigraphic correlation in East Asia.
A Silurian calymenid trilobite found in Europe and North America, distinguished by its robust, heavily calcified glabella and commonly preserved in enrolled posture.
Homalonotus is a Silurian-Devonian trilobite genus with a smooth carapace and elongated thorax, first described from European deposits.
An Ordovician trilobite genus with a rounded, convex exoskeleton known from Paleozoic marine deposits, representing a minor element of early Paleozoic trilobite faunas.
The Helderberg Escarpment is a prominent limestone cliff in New York State, USA, notable for its rugged terrain and providing extensive views across the Hudson River Valley.
Silurian dalmanitid trilobite distributed across North America and Europe, recognized by schizochroal eyes and a spinose pygidial axis.
A Late Ordovician trilobite from North America and Europe, Symphysops is notable for its fused eyes forming a single continuous bar across the cephalon.
The Onondaga Escarpment is a notable limestone ridge in New York and Ontario, famous for containing the Onondaga Cave system and exposing Middle Devonian age fossils.
