Scientists hail stunning fossil
By Christine McGourty
Science correspondent, BBC News
The beautifully preserved remains of a 47-million-year-old, lemur-like creature have been unveiled in the US.
The preservation is so good, it is possible to see the outline of its fur and even traces of its last meal.
The fossil, nicknamed Ida, is claimed to be a "missing link" between today's higher primates - monkeys, apes and humans - and more distant relatives.
But some independent experts, awaiting an opportunity to see the new fossil, are sceptical of the claim.
And they have been critical of the hype surrounding the presentation of Ida.
The fossil was launched amid great fanfare at the American Museum of Natural History in New York, by the city's mayor.
