Answer:
The animals are dust-wallowing.
Explanation:
The Altamira Cave is situated in northern Spain. It is famous for its polychromatic paintings and rock-engravings. An anthropologist who studied the Altamira Cave concluded that the animals that are depicted are not dead but dust-wallowing. Before, the animals were described as dead or asleep. But afterward, they were seen as wallowing in the dust. This is common behavior during the mating season of the bison.
