First report of penaeid (Crustacea, Decapoda, Penaeoidea) from the Lower Cretaceous (Albian) of the Tlayúa quarry, Tepexi de Rodríguez (Puebla, Central Mexico)

Resumen

The first penaeid from
the Lower Cretaceous (Albian) of the Tlayúa quarry, Tepexi de
Rodríguez (Puebla, Central Mexico) is here reported. The specimen
has been tentatively assigned to the superfamily Penaeoidea
Rafinesque-Schmaltz, 1815, for the lack of main diagnostic
characters. Despite the incompleteness of the body, it is the second
report of penaeid from the Lower Cretaceous of Mexico, increasing
the scarce knowledge about the decapod assemblage of Tepexi de
Rodríguez basin.
