Hondonadia

It was a small animal, with estimates of the body weight of the mammal ranging from 27 to 93.3 grams (0.95 to 3.29 oz). The species H. feruglioi and H. praecipitia were possibly larger. Its main diet probably consisted of seeds rather than insects.^[4] The type species Hondonadia feruglioi preserves at least four upper incisors (of which the posteriormost is the smallest), but the presence of five teeth cannot be ruled out. H. feruglioi also preserves a very large, subvertical C1.^[5]

Fossils of the genus were found in the Tinguiririca fauna of the Abanico Formation of Chile, the Santa Rosa local fauna of the Yahuarango Formation in Amazonian Peru and in the Gran Barranca fauna of the Vera Member pertaining to the Sarmiento Formation in Argentina.^[6]
