Tarsopterella is a genus of prehistoric eurypterid classified within the family Hardieopteridae. It contains only one species, T. scotica from the Lower Devonian of Scotland. [1]
Tarsopterella is distinguished by its prosoma (head), which is subrectangular and slightly concave in front, with small compound eyes. Its abdomen has pronounced lateral epimera (marginal spines similar to those of horseshoe crabs). Tarsopterella dates from the Lower Devonian period. [2]
Dolichopterus is a genus of prehistoric sea scorpions, arthropods in the order Eurypterida. Fossils of Dolichopterus have been discovered in deposits ranging from Silurian to Devonian, and have been referred to several different species, some of them of dubious affinity to this genus.
Drepanopterus is an extinct genus of eurypterid and the only member of the family Drepanopteridae within the Mycteropoidea superfamily. There are currently three species assigned to the genus. The genus has historically included more species, with nine species having been associated with the genus Drepanopterus. Five of these have since been proven to be synonyms of pre-existing species, assigned to their own genera, or found to be based on insubstantial fossil data. The holotype of one species proved to be a lithic clast.
Ctenopterus is a genus of prehistoric eurypterid of the family Stylonuridae. It contains only one species, Ctenopterus cestrotus from the Early Silurian of Otisville, New York.
Moselopterus is a genus of prehistoric eurypterid from the Devonian period in Europe. The genus contains three species, M. ancylotelson and M. elongatus from Germany and M. lancmani from Latvia.
Kokomopterus is a genus of prehistoric eurypterid. The genus contains a single species, Kokomopterus longicaudatus, known from the Silurian of Kokomo, Indiana.
Erieopterus is a genus of prehistoric eurypterid found in Silurian to Devonian-aged marine strata of Europe and North America. The genus contains eight species from the Silurian to the Devonian, recovered from both North America and Europe.
Parastylonurus is a genus of prehistoric eurypterid. It is classified within the Parastylonuridae family and contains three species, P. hendersoni and P. ornatus from the Silurian of Scotland and P. sigmoidalis from the Silurian of England.
Stylonurella is a genus of prehistoric eurypterid. It is classified within the Parastylonuridae family and contains three species, S. arnoldi and S. beecheri from the Devonian of Pennsylvania, United States and S. spinipes from the Silurian of Kip Burn, Scotland.
Strobilopterus is a genus of prehistoric eurypterid of the family Strobilopteridae. The genus contains four species, two from the Devonian of Wyoming, United States, one from the Devonian of Ohio, United States and one from the Silurian of Estonia.
Stylonurus is a genus of prehistoric eurypterid of the family Stylonuridae. The genus contains three species: Stylonurus powriensis from the Devonian of Scotland, Stylonurus shaffneri from the Devonian of Pennsylvania and Stylonurus perspicillum from the Devonian of Germany.
Stylonuroides is a genus of prehistoric eurypterid. The genus is classified as a stylonurine but more precise classification has proven difficult, with the genus remaining classified as incertae sedis within the suborder. The genus contains two species, S. dolichopteroides from the Silurian of Ringerike, Norway and S. orientalis from the Devonian of Lake Shunet, Southern Siberia.
Rhenopterus is an extinct prehistoric eurypterid. Fossils of Rhenopterus have been recovered from deposits of Lower Devonian age in Germany.
Hallipterus is a genus of prehistoric eurypterid classified as part of the family Hardieopteridae.
Pagea is a genus of prehistoric eurypterid classified as part of the family Stylonuridae. It contains three species, all from the Devonian ; P. plotnicki from Nunavut, Canada and P. sturrocki and P. symondsii from the Old Red Sandstone of the United Kingdom. The genus is named in honor of David Page, an early worker on the fauna of the Old Red Sandstone and describer of the first Stylonurine eurypterid.
The Rhenopteridae are a family of eurypterids, an extinct group of chelicerate arthropods commonly known as "sea scorpions". The family is the only family currently contained in the superfamily Rhenopteroidea, one of four superfamilies classified as part of the suborder Stylonurina.
Eurypteroidea are an extinct superfamily of eurypterids. It contains three families and two genera of uncertain classification, Paraeurypterus and Pentlandopterus.
Leiopterella is a genus of prehistoric eurypterid of the family Rhenopteridae. It contains one species, Leiopterella tetliei, from the Early Devonian of Nunavut, Canada. The name is said to be derived from the Greek leios and pteros. The proper word for wing in ancient Greek is however pteron (πτερόν). The species name honors Dr. O. Erik Tetlie for his contributions to the study of fossil eurypterids.
Onychopterellidae are an extinct family of eurypterids. The family is the only family classified as part of the superfamily Onychopterelloidea. Genera included are Alkenopterus, Onychopterella and Tylopterella.
Moselopteridae are an extinct family of eurypterids. It is the only family classified as part of the superfamily Moselopteroidea, and contains three genera: Moselopterus, Stoermeropterus and Vinetopterus.
Vinetopterus is a genus of prehistoric eurypterid from the Devonian period in Europe classified as part of the Moselopteridae family. The genus contains two species, both from Germany: V. struvei and V. martini.
