Lyuba, a baby mammoth that suffocated in thick mud 42,000 years ago, gets the high-tech treatment with this computed tomography (CT) scan.
An older mammoth, Khroma, also came from the Siberian permafrost, where she died as a baby.
A view of Khroma's skull, showing her teeth. The mammoth had unusual thick bony structures on her skull, which researchers compared to mustache-like structures.
An oblique view of Khroma's entire body. The mammoth was originally identified as male, but turned out to be female.
A somewhat crumpled, but almost entirely complete specimen, Khroma has been on display around the world.
Two baby mammoths, Lyuba and Khroma, side-by-side.
This image reveals a sharp look at baby mammoth Lyuba's ribs. Khroma's spine is well-defined.
Lyuba and Khroma in profile. Despite being presumably the same species, the mammoths had very different skeletal structures. The reason for this is still an Ice Age mystery.
The scans revealed not only bones, but muscle, organs and even stomach contents. Researchers hope to learn more about these animal's lives and adaptations to their frigid Siberian homes.
