The oldest record of flea/armadillos interaction as example of bioerosion on osteoderms from the late Miocene of the Argentine Pampas
We describe perforations recognized in mobile osteoderms of the extinct armadillos (Cingulata, Dasypodidae) Chasicotatus ameghinoi (Euphractinae, Eutatini) and Vetelia perforata (Euphractinae, Euphractini), recovered from the late Miocene of Argentine Pampas. We interpret that fleas corresponding to...
