After an initial examination, archaeologists excavated further and uncovered more remains, which they estimated to be around 40,000 years old.
They identified the main skull as an African Neanderthal and named it Irhoud 1. The timeline took a huge leap backward in 2017, when researchers determined that the fossils were actually around 315,000 years old and belonged to Homo sapiens. Now, a recent breakthrough has pieced together bare bones and given them a face—digitally.
Researchers combined images and video of the main skull fragment, Irhoud 1, with jaw and tooth fragments from other specimens found in the same archaeological layer to create a composite 3D skull. They then reshaped a modern human anatomical model to fit the skull, adding estimated muscles, fat and skin. The result was two versions of the reconstructed face.
The first was a grayscale, hairless reconstruction focused on anatomy, mapping the contours of the skull without distracting details. The second was a full-color digital face with skin tone, lighting, hair and a beard, designed to look like a person for public display. The fossils found at Jebel Irhoud are the oldest known remains of Homo sapiens, dating back around 315,000 years.
Unfortunately, no complete face survived, leaving researchers with limited evidence for recreating what our early ancestor looked like. In this study, the researchers developed a way to combine the fossil fragments into a 3D composite skull, using mostly open-source technology. They turned open-access videos and images released by the Max Planck Institute into a 3D digital skull.
Using a 3D CT scan of a modern adult human skull as a reference, the team applied a technique called anatomical deformation to digitally stretch and adjust the model until it matched the ancient fossil skull's shape and contours. The team then fitted the digital model inside the skull vault, allowing them to extract a digital mold of the brain cavity, known as an endocast. They used its measurements to calculate an estimated volume of 1,364 mL.
