OSSO, Àlex  e  DIAZ ISA, Manuel. Cantabroxanthus loredoensis new genus, new species (Decapoda, Brachyura, Etyoidea) from the Middle Campanian of Loredo, Ribamontán al Mar, (Cantabria, northern Spain). Bol. Soc. Geol. Mex [online]. 2014, vol.66, n.3, pp.483-489. ISSN 1405-3322.

The discovery of Cantabroxanthus loredoensis n. gen., n. sp., from the Sponge Beds (middle Campanian) of Cantabria (Spain), increases the number of known Cretaceous brachyuran taxa that the coastline outcrops of Cantabria have yielded. The new genus is herein placed within the family Feldmanniidae (Etyoidea) on the basis of similarities with the genus Caloxanthus A. Milne-Edwards, 1864. Cantabroxanthus is also compared to the Palaeocorystoidea families, however important differences, for example, Cantabroxanthus possesses an entire supraorbital margin, preclude any relationship with Palaeocorystoidea.
