Pterygotioidea - Wikipedia
WEBPterygotioidea (the name deriving from the type genus Pterygotus, meaning "winged one") is a superfamily of eurypterids, an extinct group of aquatic arthropods. Pterygotioids were the most derived members of the infraorder Diploperculata and the sister group of the adelophthalmoid eurypterids.
Eurypterid (Sea Scorpion) Facts and Information - FossilGuy.com
WEBMost Eurypterids were under 10" in length, but some genera, such as Pterygotus and Jaekelopterus could reach lengths of over 7 feet, and may have been the largest arthropods to ever live. Eurypterids have a nearly global distribution, but are rare as complete fossils.
Miguasha: Pterygotus
WEBThe best preserved are pieces of the sixth pair of appendages, the ones that may have been used for swimming. They display a strong resemblance to the genus Pterygotus, the largest of all the eurypterids, which surpassed two metres. In fact, Pterygotus was the largest arthropod of all time.

WEBAug 17, 2024 · Giant water scorpion, any member of the extinct subclass Eurypterida of the arthropod group Merostomata, a lineage of large, scorpion-like, aquatic invertebrates that flourished during the Silurian Period (444 to 416 million years ago).
The origin of pterygotid eurypterids (Chelicerata: Eurypterida)
WEBSep 15, 2009 · Abstract: The Silurian and Lower Devonian pterygotid eurypterids were the largest of all arthropods, but their origin and early evolution are poorly understood. Pterygotus? ventricosus from Kokomo, Indiana, is shown to be the most basal of the pterygotids and constitutes the sister taxon to the rest of the clade.

WEBEurypterid, member of an extinct order (Eurypterida) of unusual arthropods rarely preserved as fossils. The eurypterids appeared at the beginning of the Ordovician Period (about 488 million years ago) and became extinct at the end of the Permian Period (about 251 million years ago).
Ex vivo three-dimensional reconstruction of Acutiramus : a giant ...
WEBBy documenting specimens displaying important dorsal and ventral structures from both Acutiramus—a larger, well-documented pterygotid genus—and other pterygotids, we reconstruct Acutiramus in three-dimensions (3D) to more thoroughly understand the functional morphology and limb arrangement of these large eurypterids.
Pterygotus - Simple English Wikipedia, the free encyclopedia
WEBPterygotus anglicus is an extinct Eurypterid, related to arachnids (the spider family) and commonly called "sea scorpions." It lived in the Silurian and Devonian periods. Fossils have been found in North America, South America, Europe and Australia. It is related to the larger Jaekelopterus.
