Baby mammoth on display

Chicago - Some 42 000 years after scientists say she fell into mud near a river and suffocated, an intact baby woolly mammoth from the Ice Age is to go on display for the first time in the US at The Field Museum.

Scientists said the mammoth calf, named Lyuba, is the best preserved and most complete mammoth specimen known. She was found in 2007 by a reindeer herder in northern Siberia's remote Yamal-Nenets autonomous region and named for his wife.

"Her preservation, her really lifelike qualities allow you to form a better impression of what the past was really like," said Dan Fisher, a University of Michigan palaeontologist and the museum's exhibit curator. "It becomes more immediate. It's real."

In the exhibit that opens on Friday, visitors can see the folds and creases in Lyuba's skin, the bottom of her foot and small patches of hair on her ear and leg. At 114cm long, Lyuba weighs about 42kg and if fully grown could have measured 2.4 metres tall at her shoulder and weighed between 2.7 and 3.6 metric tons, Fisher said.

Lyuba has been a boon for scientists, who have done MRIs, CT scans and DNA testing among other analyses on the baby mammoth.

Great gift

"The things you can learn from a fleshy specimen like this that you can't learn from studying a skeleton," said Tom Skwerski, The Field Museum's project manager for the exhibit. "It's as if all of a sudden you've been given this great gift to be able to reaffirm a lot of your theories."

Scientists have analysed Lyuba's stomach contents, including her mother's milk. They say she was one month old when she died and was in excellent condition.

Scientists first analysed Lyuba's baby tusks and chewing teeth, looking for details about diet, environment and health.

"The important thing about Lyuba, though, is that in a sense she gave us the answers to many of the questions we would ask through those analyses," Fisher said. "Because there's her whole body preserved in its entirety."

Experts say the baby mammoth remained well-preserved because she was frozen in permafrost for thousands of years. Fisher also said her body was colonised by naturally occurring bacteria that produced lactic acid, which kept her body in a "pickled" state.

Lyuba's body was immersed in preservative solutions for her Chicago display, scientists said. Skwerski called the baby mammoth a "singular object" and said she has been valuable to scientists around the world.

"To get Lyuba for our exhibition is like getting the Mona Lisa for your exhibition on Italian art," Skwerski said.

Value

The baby mammoth's true value may be in her ability to bring people closer to human history, the history of the Earth's climate system and climate change, Fisher said.

"If Lyuba opens people's minds to any of that, then she's doing a great job for us," he said.

The baby mammoth's home institution is the Shemanovskiy Museum and Exhibition Centre in Salekhard, Russia. She is the centrepiece of a larger multimedia exhibition at the Field called Mammoths and Mastodons: Titans of the Ice Age until September 6.

The exhibit is to travel to other North American cities: Jersey City, New Jersey; Anchorage, Alaska; St Louis, Missouri; San Diego, California; Denver, Colorado; and Boston, Massachusetts.
