Abstract A new species of homolid crab, Zygastrocarcinus tricki sp. nov., is reported from the Late Cretaceous (middle Campanian, Baculites scotti Zone) of the Pierre Shale Formation (Baculite Mesa, Pueblo County, Colorado). This nearly complete homolid, hereto described is the sixth species assigned to the genus and extends our knowledge along with the geographical range and geological age of this taxon.
