Ophthalmoplax (Decapoda: Brachyura: Portunoidea) from the late Campanian, Upper Cretaceous, of Colombia

Abstract

A new species of the brachyuran Ophthalmoplax is documented based upon two specimens collected from shales of the Lodolitas de Aguacaliente Formation, Guadalupe Group, (Cordillera Oriental, Colombian Andes), which represents a regional transgressive event. The small crustaceans were found in the uppermost parasequences with retrogradational stacking pattern, near to the maximum flooding surface (MFS), at the end of the late Campanian Transgressive Systems Tract (TST). This is the oldest record for Ophthalmoplax in America. Morphological affinities with other species of the genus are discussed, including size reduction related with anoxia events and paleotemperature.Keywords: Crustacea, Portunoidea, Ophthalmoplax andina n. sp., Campanian, anoxia, Colombia.

“…After the paper by Guzmán et al (2016) was published, an error related to the catalog numbers of the fossils specimens was pointed out. The codes UN-DG-CR-021 and UN-DG-CR-022 had already been used in the description of Colombian specimens of the lobster Meyeria magna M'Coy, 1849, in the publications of González-León (2016) and González-León et al (2016), forcing us to replace these numbers.…”
