The paleoenvironmental significance of trace fossils from the Cárdenas Formation (Late Cretaceous, Maastrichtian) at Potrero del Carnero, San Luis Potosí, central Mexico

ABSTRACT This paper documents the occurrence ofSkolithos linearis, Planolites beverleyensis,andThalassinoidesisp. in the Cárdenas Formation (Late Cretaceous), southeastern San Luis Potosí, central Mexico. This is the second record ofS. linearisfor this lithological unit, whileP. beverleyensisandThalassinoidesisp. are documented for the very first time in this formation. The ichnoassemblage is referred to theCruzianaIchnofacies which, in concert with associated invertebrate body fossils (Exogyra costata), suggest a shoreface setting with moderate- to low-energy conditions and episodic storms.
