Pterygotus is an extinct genus of giant predatory eurypterid, a group of extinct aquatic arthropods. Fossils of Pterygotus have been discovered in deposits ranging in age from Middle Silurian to Late Devonian , and have been referred to several different species.
Pterygotidae (the name deriving from the type genus Pterygotus, meaning "winged one") is a family of eurypterids, an extinct group of aquatic arthropods.They were members of the superfamily Pterygotioidea.
Pterygotioidea (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.
Since the first printing of Carl Linnaeus's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. [1] Many of these plants are listed in Stearn's Dictionary of Plant Names for Gardeners .
The fourth eurypterid genus to be described (following Hibbertopterus in 1836 and Campylocephalus in 1838, not identified as eurypterids until later), out of those still seen as taxonomically valid in modern times, was Pterygotus (lit. ' winged one '), described by Louis Agassiz in 1839. [84]
At a length of 2.1 metres (6.9 feet), A. bohemicus is the largest known species of the genus, [1] whilst the smallest were A. floweri and A. perryensis both at a length of 20 cm (7.9 in). [2] The body of Acutiramus was very slender, with members of the genus being almost five times as long as they were wide. [3]
Restoration of E. osiliensis.. Erettopterus was a big eurypterid, with E. osiliensis, the largest species, measuring approximately 90 cm (35 in) in length. [1] Though this is large relative to most modern day arthropods, Erettopterus was small in comparison of many of the members of its family (the Pterygotidae), such as Jaekelopterus rhenaniae at 2.5 m (8 ft) (the largest known arthropod) and ...
A taxon (e.g., species or genus; plural: taxa) named in honor of another entity is an eponymous taxon, and names specifically honoring a person or persons are known as patronyms. Scientific names are generally formally published in peer-reviewed journal articles or larger monographs along with descriptions of the named taxa and ways to ...
