Early people had no written language. Their laws, cultural beliefs, and myths were preserved through stories, dances, songs, and paintings. Cave paintings perhaps the favorite way for early humans to maintain information for the coming generations. Time to time there was a significant improvement in the information which early humans shared through the cave paintings. Here you can see another example of aesthetic drawings made by megalithic ancestors which explain not only the mammals but their inner organs as well.
Aboriginal Style Art
X-ray style art is a prehistoric rock art depicting animals by drawing or painting the skeletal frame and internal organs.
It can be found in Mesolithic art in Europe from 8000 BCE onward and apparently spread far and wide from an unknown center, as to reach Africa, South Asia, and Australia by 2000 BCE.
Images are known in which only the outline and the skeleton of the bird, fish, or mammal are indicated, and the entire internal system of organs is expressed by a “lifeline,” a single horizontal line that runs from the animal’s mouth to a dot representing the heart or stomach.
It is found today primarily in the Aboriginal rock, cave, and bark paintings of eastern Arnhem Land, in northern Australia. Figures painted in X-ray style vary in size up to 8 feet (2.5 m) in length and are delicate, polychromed renderings of the interior cavity of the animal.

The Mimi spirits
The Mimi spirits are fairy-like beings of Arnhem Land in the folklore of the indigenous people of northern Australia. Westerners would equate them with elementals and nature spirits.
They are depicted as having thin and elongated bodies–so thin as to be in danger of breaking in case of high wind. To avoid this fate, the Mimis spend much of their time living in rock crevices.
As creation spirits, they are like humans but exist in a different dimension. It was the Mimis who first taught the people how to hunt, cook and paint.

Religious and Cultural Significance
Whether the depiction of an animal in the X-ray style had articular religious symbolism is not known.
This looks a clear case of an early diffusion of a cultural feature, interestingly one that occurred several tens of thousands of years after the Out of Africa event.
Otherwise, how did people come up with the same idea of showing the interiors of animals and humans? Or, more likely, did the concept predate its appearance in Stone Age art?
