Researchers used 3D and CT scans to reconstruct her image.

The skull consists of nine pieces, which are under the care of the Department of Anthropology of the National Museum in Prague, Czechia. Even though a considerable part of the skull remains, some parts of the structure, like the nasal bone, maxilla, left orbit, and the left part of the frontal bone, are missing.

"An interesting piece of information about the skull is that it was gnawed by an animal after her death," Moraes toldMoraes and his team of researchers used the data collected from 2018 computed tomography scans of the woman’s skull. In 2018, a multinational team of researchers created a 3D reconstruction of the missing regions, using statistical data extracted from a group composed of 30 skulls – 15 men and 15 women in France.

The researchers initially mirrored the 3D mesh in order to reconstruct as many of the missing regions as possible using the original anatomy of the skull, yet some areas remained empty. Such regions were complemented by statistical data extracted from the CT scans and the aforementioned fossil, resulting in a complete skull, wrote the researchers in the paper.

"Once we had the basic face, we generated more objective and scientific images, without coloring, with eyes closed and without hair," Moraes said. "Later, we created a speculative version with pigmented skin, open eyes, fur and hair. The objective of the second is to provide a more understandable face for the general population."
