Eurypterid trackways have been referred to several ichnogenera, most notably Palmichnium (defined as a series of four tracks often with an associated drag mark in the mid-line), [24] wherein the holotype of the ichnospecies P. kosinkiorum preserves the largest eurypterid footprints known to date with the found tracks each being about 7.6 ...
Palmichnium ("palm trace") is an ichnofossil genus, interpreted as a eurypterid trackway. It has been found by many places around the world, such as Australia, Canada, United States and Wales . Its trackways consist of three or four subcircular tracks that are symmetrical around a midline impression that is arranged en echelon with a high angle ...
Eurypteridae is an extinct family of eurypterids that lived in the Silurian and Devonian periods. The family is one of three families contained in the superfamily Eurypteroidea (along with Dolichopteridae and Strobilopteridae), which in turn is one of the superfamilies classified as part of the suborder Eurypterina.

Eurypterus, the most commonly found eurypterid fossil and the first eurypterid genus to be described. This list of eurypterid genera is a comprehensive listing of all genera that have ever been included in the order Eurypterida, excluding purely vernacular terms.
Megalograptidae are a family of eurypterids, an extinct group of chelicerate arthropods commonly known as "sea scorpions".. The megalograptids were likely the first major successful group of eurypterids, evidenced by a Late Ordovician radiation.
Mycteroptidae are a family of eurypterids, a group of extinct chelicerate arthropods commonly known as "sea scorpions". The family is one of three families contained in the superfamily Mycteropoidea (along with Hibbertopteridae and Drepanopteridae), which in turn is one of four superfamilies classified as part of the suborder Stylonurina.
Seventy-five percent of eurypterid species are eurypterines; this represents 99% of specimens. [2] The superfamily Pterygotioidea is the most species-rich clade, with 56 species, followed by the Adelophthalmoidea with 43 species; as sister taxa, they comprise the most derived eurypterines.
