Abstract

New specimens from the Eocene of Nigeria yielded one new genus and species, Amekicarcinus enigmaticus, and the new species Glyphithyreus bendensis. Indeterminate remains of an axiid decapod were also collected from the same deposit. Nigerian decapod occurrences in general display a Tethyan or Paratethyan distribution in the Eocene, whereas Cretaceous occurrences include Atlantic distributions in addition. Many Nigerian decapod genera cross the K/Pg boundary in the Atlantic, proximal to the Chicxulub impact area.
