Abstract

The putative fossil whipscorpion Thelyphonus hadleyi Pierce 1945 (Arachnida: Uropygi) from the middle to late Miocene Monterey Formation of Cabrillo Beach, San Pedro, California is reassessed. It is shown here to be nothing more than a fortuitously shaped stain on the rock, apparently partly algal in nature. The fossil record of whipscorpions can thus be restrained to six Pennsylvanian and one Cretaceous species.
