Thimdror

A thimdror was a breed of oxen. They were small, broad-shouldered animals with ugly bald and almost triangular, reptilian heads.

Ecology
Thimdrors could live to be up to 30 years old if they lived in areas with the appropriate conditions, as they couldn't tolerate eeither very hot climates or specially cold winters.

Uses
Although incredibly strong, the thimdrors were not favored as draft beasts because of their small size and stupid behavior. However, they were highly prized all around the Realms for their delicious marbled meat.
