Unidentified Spider
aff. Miagrammopes
Green River Formation
Parachute Creek Member
Middle Eocene
Uintah County, Utah

This is a very excellent fossil spider from the Parachute Creek beds in Utah. All eight legs are present. Leg spread is about 1 cm. Fossil spiders are very rare but this is a very fine specimen. A recent paper by Paul Selden (Arthropoda Selecta V23-2 pp 207-219) adds significant knowledge to fossil spiders from this formation.
