...it isn’t surprising that this [necrophagous] habit in armadillos has led to various concerns and superstitions: the idea that armadillos might excavate graves and consume the recently deceased is present in several areas, most famously in the Paraguayan Chaco. There are also all kinds of rumours about armadillos being especially abundant, or especially plump and healthy, in or near cemeteries.

An odd tidbit lifted from this longer piece from Tetrapod Zoology on predatory armadillos.
