"Lyuba" gives scientists glimpse of mammoth insides

By Dmitry Solovyov

MOSCOW (Reuters) - Russian scientists say they have obtained the most detailed pictures so far of the insides of a prehistoric animal, with the help of a baby mammoth called Lyuba found immaculately preserved in the Russian Arctic.

The mammoth is named after the wife of the hunter who found her last year. The body was shipped back to Russia in February from Japan, where it was studied using computer tomography in a process similar to one doctors use to scan patients.

"We could see for the first time how internal organs are located inside a mammoth. It is pretty important from a scientific point of view," said Alexei Tikhonov, deputy director of the Russian Academy of Science's Zoological Institute, who has been leading the project.

"Her internal organs were well preserved -- the heart was seen distinctly with all its ventricles and atria, as well as the liver and its veins," Tikhonov told Reuters.

"This is the best preserved specimen not only of the mammoth but of any prehistoric animal."

The mammoth species has been extinct since the Ice Age. Tests on Lyuba showed she was fed on milk and was three to four months old when she died 37,000 years ago in what is now the Yamalo-Nenetsk region in Russia's Arctic.

Scientists were excited by the find because, although her shaggy coat was gone, her skin was intact, protecting her internal organs from contamination by modern-day microbes.

Tikhonov said the computer tomography, which provided a sharp three-dimensional image of Lyuba's insides, revealed no injuries or fractures.
