Venustulus

Venustulus is a genus of synziphosurine,[1] a paraphyletic group of fossil chelicerate arthropods.[2][3] Venustulus was regarded as part of the clade Prosomapoda.[2][4][5][6][3][7] Fossils of the single and type species, V. waukeshaensis, have been discovered in deposits of the Silurian period in Wisconsin, in the United States.[1][2][7] Venustulus is one of the few synziphosurine genera with fossil showing evidence of appendages.[1][3]
