A cretaceous hermit crab from antarctica: Predatory activities and bryozoan symbiosis

A hermit crab assigned to Paguristes sp. is described from James Ross Island, Antarctica. The fossil was obtained from the Gamma Member of the Santa Marta Formation of late Campanian age. The specimen is associated with an external mould of the gastropod Taioma, that was encrusted by a colony of asc...
