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.^[1] The genus contains two species, S. dolichopteroides from the Silurian of Ringerike, Norway and S. orientalis from the Devonian of Lake Shunet, Southern Siberia.^[2]
