Pagea

Pagea is a genus of prehistoric eurypterid classified as part of the family Stylonuridae. It contains three species, all from the Devonian (Lochkovian to Pragian);[1] P. plotnicki from Nunavut, Canada and P. sturrocki and P. symondsii from the Old Red Sandstone of the United Kingdom.[2] 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.[3]

Description

Pagea was a large stylonurid eurypterid. The third and fourth prosomal appendages bore double rows of flat spines. The prosoma was subrectangularly shaped, with the eyes located on the anterior half.[3]

The metastoma was narrow in relation to the width of the prosoma, being half as wide as it was long. The telson was styliform, long and keeled.[3]
