Cancrinos
''Cancrinos'' is a genus of fossil crustacean closely allied with the slipper lobsters. Two species are known, ''C. claviger'' from the Jurassic of southern Germany and ''C. libanensis'' from the Cretaceous of Lebanon. ==Taxonomy== Fossils of ''Cancrinos'' are rare, and their state of preservation is often imperfect. Count Georg zu Münster first described ''Cancrinos'' in 1839, based on material from the Upper Jurassic Solnhofen limestones of southern Germany. He described two species, ''Cancrinos claviger'' and ''C. latipes'', differentiated by the size of the second antennae,〔 but the two are now considered to be synonyms.〔 Further specimens have been discovered in Upper Cretaceous lithographic limestones of Lebanon, and described as a new species, ''C. libanensis''; however, Haug ''et al.'' (in press) made it the type species of a separate genus ''Paracancrinos''.
