A brief review of other known Devonian trigonotarbids is presented, and certain misconceptions about the order are rectified, including the nature of the eyes, chelicerae, claws, and abdominal segmentation. Trigonotarbida is shown by cladistic analysis to be the plesiomorphic sister-group of Araneae + Amblypygi + Uropygi + Schizomida"--P. 2.26931054 bytesapplication/pdfen-USQL1 .A436 no.2901, 1987Gilboarachne griersoni.Gelasinotarbus.Aculeatarbus depressus.Arachnida, Fossil -- New York (State) -- Gilboa Region.Paleontology -- Devonian -- New York (State) -- Gilboa Region.Paleontology -- New York (State) -- Gilboa Region.text
