Camanchia
Extinct genus of arthropods
From Wikipedia, the free encyclopedia
Camanchia is a genus of synziphosurine,[1] a paraphyletic group of fossil chelicerate arthropods.[2][3] Camanchia was regarded as part of the clade Prosomapoda.[4][5][6][3] Fossils of the single and type species, C. grovensis, have been discovered in deposits of the Silurian period in Iowa, in the United States.[7][2] Alongside Venustulus, Camanchia is one of the only Silurian synziphosurine with fossil showing evidence of appendages.[1]

The prosoma of Camanchia covered by a smoothly curved subtriangular carapace with broad doublure (ventral thickening run through the margin of carapace).[1] Detail of the 6 prosomal appendage pairs (chelicerae+5 leg pairs) obscure, at least the first leg pair (appendage II) have spur-like terminations.[1] Opisthosoma is externally 10-segmented with tergites possess blunt pleurae (lateral extension).[1] The last 3 opisthosomal segments forming a narrow postabdomen with short pleurae.[1] Telson is yet to be discovered.[1] The carapace margin and pleurae possess tubercles.[1]
