FRAAIJE, Rene H. B  and  PENNINGS, Henri W. J. Crab carapaces preserved in nautiloid shells from the Upper Paleocene of Huesca: Pyrenees, Spain. Rev. mex. cienc. geol [online]. 2006, vol.23, n.3, pp.361-363. ISSN 2007-2902.

Carapaces of three species of crab, found -within specimens of the nautiloid Eutrephoceras. are described from the Upper Paleocene of Huesca (Pyrenees, Spain). This is the first record of the use by crabs of empty cephalopod shells for moulting from the Cenozoic; this phenomenon may have been more widespread.

Keywords : crab; nautiloids; inquilinism; Paleocene; Pyrenees; Spain.
