A scene on Earth during the Quaternary period

A highly realistic scene depicting Earth during the Quaternary period: sprawling plains of grasslands and tundra under a cloudy sky, with herds of woolly mammoths, massive shaggy rhinoceroses, saber-toothed cats, and early humans in animal hides. Snow patches cover the ground, and in the distance, glaciers and mountains loom. Every detail—the fur textures, the breath in cold air, the ancient flora—should be vividly lifelike and true to Quaternary period environments.
