1. UA 8653, the holotype, is hypsodont and curved. 2. Their teeth are hypsodont , and their dental formula is: 3. The incisors and cheek teeth of rabbits are called aradicular hypsodont teeth. 4. The molars are relatively high-crowned ( hypsodont ). 5. The enamel of hypsodont " Perissodactyla " is highly rugose rather than sharp. 6. They had high-crowned, hypsodont teeth which were used to chew gritty vegetation. 7. Like other sudamericids it had hypsodont molariforms. 8. The molars are more hypsodont ( high-crowned ) than in other " Thomasomys ". 9. In modern mammals, hypsodont teeth are often associated with diets that include abrasive vegetation such as grasses. 10. Unlike the very high-crowned ( hypsodont ) sudamericids, ferugliotheriid teeth were low-crowned ( brachydont ).
