"Thoatherium" is an extinct genus of litoptern mammal.

With a length of 70 cm (2 ft 4 in), the gazelle-like "Thoatherium" was the smallest representative of the order Litopterna. Judging from its long legs, it was a fast runner. "Thoatherium" had remarkably reduced toes; only one horse-like hoof remained. "Thoatherium" even lacked splint bones, which are remnants of the second and fourth toe found in modern horses. Judging from its teeth, "Thoatherium" fed on leaves.
