AbstractThe skull morphology of fossil chelids is poorly known because their fossil record is scarce. Here, we describe a new genus and species of flat-headed chelid turtle based on a partial skull. The remains derive from the Maastrichtian (Late Cretaceous) upper section of the Allen Formation at Morales Quarry, near General Roca city in the Río Negro province of Argentina.
