A review of fossil scorpion higher systematics.

ABSTRACT: Scorpions (Arachnida: Scorpiones) are a diverse and widespread arachnid order with a rich and deep fossil record. Here we review the, sometimes complex, historical development of fossil scorpion higher classification. We present a chronological account of family and genus names, together with an overview of higher taxa as potential clade names. In 1884 Thorell & Lindström divided scorpions based on whether the legs were short and pointed (Apoxypoda) or ended in paired claws (Dionychopoda). Pocock in 1911 used the morphology of the ventral mesosomal sclerites, which could either be bilobed (Lobosterni) or of a modern configuration (Orthosterni). Petrunkevitch in 1949 attached importance to a putative first opisthosomal tergite being present (Protoscorpionina) or absent (Euscorpionina). Kjel
