Concerning the fossil orders, Dunlop (1996a, b) presents a revised concept of the formerly accepted (Weygoldt and Paulus 1979; Shultz 1990) five fossil orders of Arachnida. The subclasses of Petrunkevitch (1949) have been rejected, Anthracomartida – synonymized with Trigonotarbida.

Heymons (1901), the author of the term Chelicerata, united Merostomata (Eurypterids and Xiphosurans) with Arachnida in one monophyletic group. Dunlop and Selden (1997) restricted this term to Lemoneites, Xiphosura, Chasmataspida, Eurypterida, and Arachnida. There were many attempts to create a “natural” system of the monophyletic (Wheeler et al.

AbstractOn the basis of experimental study and observations on the morphology of the legs of spiders, P. Friedrich described a cutting device within the trochanter which would sever that appendage from the body when the leg was stimulated by injury.A reinvestigation of the problem yielded entirely contrary results.
