Pasternakevia
Template:Short description Template:Automatic taxobox
Pasternakevia is a genus of synziphosurine,[1] a paraphyletic group of fossil chelicerate arthropods.[2][3] Pasternakevia was regarded as part of the clade Planaterga.[2][4][5][6][3][7] Fossils of the single and type species, P. podolica, have been discovered in deposits of the Silurian period in Podolia, Ukraine.[7][2]
The prosoma of Pasternakevia covered by a smooth, semicircular carapace with rounded genal cornua (posterolateral corner of carapace).[1] Within the 10-segmented opisthosoma, tergite of the first segment is reduced and usually hidden under the preceding carapace, while the second one is significantly arched and well-developed.[1] All but the first tergite possess well-developed pleurae (lateral extension). A complete telson is yet to be discovered.[1]
