Insect trace fossils in glyptodonts from Uruguay

Abstract

The association of vertebrate remains and invertebrate traces, although less studied than other bioerosion traces, provides important paleoecological information. This report describes Cubiculum ornatum Roberts, Rogers, and Foreman 2007 Roberts, E., R. Rogers, and B. Foreman. 2007.

They come from the Fray Bentos Formation (Late Oligocene), the Camacho Formation (Late Miocene) and the Dolores Formation (Late Pleistocene-Early Holocene). The reported traces were likely made by sarcosaprophagous beetles, which indicate depositional conditions with dry episodes in a warm climate for the referred stratigraphical units.
