Considered the oldest known horse sculpture made by anatomically modern humans (Homo sapiens), this horse-shaped figurine is carved out of mammoth ivory. The palm-sized artifact measures roughly 1 inch (2.5 centimeters) high and 1.9 inches (4.8 cm) long and includes details such as a carved mouth, nostrils, eyes and mane. Although the ivory horse’s head is complete, all four of its legs have been broken off. Archaeologists think the sculpture depicts a stallion, according to the Bradshaw Foundation, which asks, “Is this a stallion trying to impress a mare or a horse arching and kicking backwards against a predator?”
