sentences:  Only one specimen, the anterior part of a carapace with the compound eyes placed on the margin, is known and though it does resemble "Slimonia", it could also potentially be referred to "Hughmilleria" or even represent the carapace of "Salteropterus abbreviatus" (a closely related slimonid eurypterid known only from the telson and metastoma, a large plate part of the abdomen).The fossils were recovered from deposits of Pridoli (Late Silurian) age in Herefordshire, England and suggest that the species grew to 12 cm (5 in) in length.Due to its problematic nature, "S. stylops" is seen as a "nomen dubium" by modern researchers.
