The oldest record of flea/armadillos interaction as example of bioerosion on osteoderms from the late Miocene of the Argentine Pampas
RL Tomassini, CI Montalvo, MC Ezquiaga - International Journal of …, 2016 - Elsevier
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 the genus Tunga (Siphonaptera) produced
these marks. These parasites locate in the carapace of the host, perforating the osteoderms
by mechanical and chemical processes as the neosome grows. This finding constitutes the …
