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.
Agassiz first thought the fossils represented remains of fish, only recognizing their nature as arthropod remains five years later in 1844. [85] In 1849, Frederick M'Coy classified Pterygotus together with Eurypterus and Belinurus (a genus today seen as a xiphosuran) within Burmeister's
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]
The first pterygotioid fossils to be uncovered were those of the type genus, Pterygotus. Louis Agassiz, a Swiss-American biologist and geologist, described the fossils in 1839 and named the genus Pterygotus, meaning "winged one". Agassiz mistakenly believed that the fossils were the remains of a large fish. [9]
The earliest eurypterid reconstruction; a figure of Eurypterus remipes by James E. De Kay (1825).. This timeline of eurypterid research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, and taxonomic revisions of eurypterids, a group of extinct aquatic arthropods closely related to modern arachnids and horseshoe crabs that lived during the ...
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups.Ambiguous common names are accompanied by their possible meanings.
Illustration of the holotype specimen of "Pterygotus rhenaniae", a pretelson, by Otto Jaekel, 1914. Jaekelopterus was originally described as a species of Pterygotus, P. rhenaniae, in 1914 by German palaeontologist Otto Jaekel based on an isolated fossil pretelson (the segment directly preceding the telson) he received that had been discovered at Alken in Lower Devonian deposits of the ...
