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.
The BBC's Fergus Walsh visits the Messel Pit, near Darmstadt in Germany, where the fossil was unearthed.
