Re-evaluation of Preclarocarcinus parvus Schweitzer, Feldmann, Ćosović, Ross & Waugh, 2009 (Decapoda, Homolodromioidea) from the Upper Cretaceous (upper Santonian–lower Campanian) of Vancouver Island, British Columbia

Abstract

The monotypic genus Preclarocarcinus Schweitzer, Feldmann, Ćosović, Ross & Waugh, 2009, was described based upon the species P. parvus Schweitzer, Feldmann, Ćosović, Ross & Waugh, 2009 from the Upper Cretaceous (Campanian) of Vancouver Island. Preclarocarci- nus parvus was based on a single specimen with the front only partially preserved. Preclarocarcinus parvus was based on a single specimen with the front only partially preserved. The recent discovery, from the lower Campanian, of two complete specimens of the species which preserve the frontal region allows a re- evaluation of the type species in order to better establish its generic characters. Finally, we revise the age of the type locality of P. parvus, the genotype species, from Campanian to late Santonian. The genus Preclarocarcinus thus has an overall age range from late Santonian to early Campanian.
