ABSTRACT Necrocarcinus olsonorum, new species, is a minor element in the Linuparus faunal association from the Cretaceous Carlile Shale of Turonian Age around the northern and eastern flanks of the Black Hills Uplift in South Dakota and Wyoming. The species is characterized by a highly arched ovate carapace ornamented with rounded bosslike spines and small granules, and dorsal shield with reflexed and rounded edges. The shape, ornamentation, and stratigraphic position of this crab suggest that it is related closely to the ancestral stock of the calappids (i.e., Calappa). Fourteen specimens known from seven localities are preserved as carapaces unassociated with sterna, abdomens, or appendages, possibly indicating the fragility of the missing exoskeletal elements, and suggesting adaptation to a shallow burrowing mode of life in muddy substrates. One carapace preserved with its sternum and proximal parts of pereiopods 1-3 indicates that pereiopods 4 and 5 were reduced.
