The three mummified animals showcased in this video—a cat, a snake, and a bird—remained shrouded in bandages, and mystery, for more than 2000 years. But a new 3D look inside is revealing deeper insights into how they lived and died.

Scientists utilized so-called micro–computer tomography (micro-CT) scanning, which creates 3D images by merging thousands of 2D x-ray projections from different angles. Micro-CT provides up to 100 times higher resolution than a typical medical CT scan, meaning the researchers could zoom in to uncover much finer details without damaging the delicate specimens.
