Collins J.S.H. (2011) Venipagurus mariae gen. et. sp. nov. (Decapoda, Anomura, Venipaguroidea superfam. nov.) from the Lower Lias of Dorset, England // Bulletin of the Mizunami Fossil Museum, no. 37. P. 17–21. Pdf: http://www.city.mizunami.gifu.jp/odocs...._03.pdf
Hitherto, the earliest known pagurid remains have been of chelae preserved in an ammonite from the Lower Jurassic (Pliensbachian) of Germany. Thus, recognition of carapaces from the Jurassic, Lower Lias (Sinemurian) of Dorset, England, not only represent the earliest known evidence, but substantiates the assumption of a calcified carapace origin for pagurids. The new material is described herein as Venipagurus mariae gen. et sp. nov. and is placed in a new superfamily, Venipaguroidea.
