 | | Remains belonging to this subfamily, less abundant than other Perissodactyla groups, are present in seven localities: Casaseca, Corrales, Jambrina and El Viso-Sanzoles (middle part of the middle Eocene, MP 13-14, Zamora province), Caenes and San Morales (upper part of the middle Eocene, MP 16, Salamanca province) and Mazaterón (middle Eocene-upper Eocene, MP 16-17, Soria province). |
 | | The tortoises were found in outcrops of the Sarmiento Formation on the south side of the Chubut Valley, between Gaiman and Dolavon (Chubut Province, Argentina). |
 | | All the features characterizing the adult males are related to those concerning the largest size; the characters related to the smallest size probably correspond to female individuals. |
