The only known preserved predator attack on a large armored xenarthran is that of two elliptical punctures in the roof of the skull of a young glyptodont from the Blancan 111 Ranch locality in Arizona made by the canines of a large machairodont felid (sabertoothed cat; Gillette and Ray, 1981).
Although relatively complex for a xenarthran tooth, the molariform dentition of Paramylodon consists only of simple lobes that show much variation in development, even within the same population (Stock 1925).
