Abstract

An Early Cretaceous (Hauterivian) hermit crab perfectly preserved within an ammonite is described. Palaeontologists have focused too much on the wrong class of molluscs in their attempt to analyse the evolution of the pagurids. The shift of mollusc habitation during the Cretaceous, from ammonites to gastropods, affected the morphology of the aperture-blocking hermit-crab claws.
