Lyuba, the month-old mammoth found in Siberia in 2007 is the best-preserved baby mammoth yet found. She's about 40,000 years old and, whie she's owned by the Shemanovskiy Museum and Exhibition Center in Siberia, she has travelled extensively in her second life. She has been studied in Tokyo, displayed in Chicago's Field Museum, toured the US and is now going on display in Hong Kong before traipsing round Asia.
Lyuba was mummified after suffocating in a muddy river bed, preserving amazing detail. Her eyes and some fur was intact, her internal organs were all there and she even had some of her mother's milk in her stomach.
