Abstract:

The discovery of beautifully preserved specimens of a macruran decapod provides the basis for redescription of Hoploparia antarctica Wilckens, a hitherto poorly known species from the Campanian-Maastrichtian of the Austral Basin of Southern Patagonia. Analyses of the associated molluscan fauna, trace fossils, and sedimentary structures indicate that the material is mostly preserved in calcareous sandstones and coquinas deposited in shallow, well-oxygenated environments. These new findings of H. antarctica in Maastrichtian deposits of the Lefipan Formation of Chubut expand the geographic distribution of the species and add a new element for the comparison of the Lefipan fauna with that of the austral Wedellian Province. -Authors
