Scientists in New York unveiled on Tuesday the skeleton of what they said could be the common ancestor to humans, apes and other primates.

The tiny creature, officially known as Darwinius masillae, but dubbed Ida, lived 47 million years ago and is unusually well preserved, missing only part of a leg, or five per cent of the skeleton.
The skull of 'missing link' Ida

The unveiling of Ida, a perfectly preserved fossil thought to be the most complete primate skeleton ever discovered.

The finding, described on Tuesday in the PloS ONE scientific journal, was displayed at a press conference at New York's Natural History Museum, and is due to be the subject of a documentary on the History Channel, BBC and other broadcasters.

Organisers said that scientists led by Norway's fossil expert, professor Jorn Hurum, worked for two years on Ida, first discovered in 1983 by private collectors who failed to understand her importance - and split the bones into two lots.

The monkey-like creature was preserved through the ages in Germany's Messel Pit, a crater rich in Eocene Epoch fossils.

Although bearing a long tail, she had several human characteristics, including an opposable thumb, short arms and legs, and forward facing eyes.

She also lacked two key elements of modern lemurs: a grooming claw and a row of lower teeth known as the toothcomb.

"This is the first link to all humans - truly a fossil that links world heritage," Prof Hurum said in a statement.

David Attenborough, the renowned British naturalist and broadcaster, said the "little creature is going to show us our connection with all the rest of the mammals".

"The link they would have said until now is missing... it is no longer missing," he said.

Ida gives a glimpse into a time when the world was just taking its present shape. Dinosaurs were extinct, the Himalayas were forming and a huge range of mammals thrived in vast jungles.

According to the international team, Ida had suffered a badly broken wrist and this might have been her undoing. The theory is that while drinking from the Messel lake she was overcome by carbon dioxide fumes and fell in.

"Ida slipped into unconsciousness, was washed into the lake, and sank to the bottom, where the unique conditions preserved her for 47 million years," a statement said.

Her last meal shows she was a herbivore. Gut contents revealed remains of fruits, seeds and leaves.

"This fossil is so complete. Everything's there. It's unheard of in the primate record at all. You have to get to human burial to see something that's this complete," Hurum said.

The press conference was unusually strongly hyped for a scientific event and the announcement was tied into a media campaign including the release of the documentary. "Quote"
 
Could this be it???

Definatley not my field. Just think it would be great if it was true.

Interesting point that the press release coincides with the release of the documentry! A little cynical yes. Obviously this work has a huge cost! Considering most of the time they find nothing new :p

I read one source (Daily Mail, I think it was) that said some scientists believed that she was more of an "aunt" than a direct ancestor of man.
 
Its interesting as who gets to have final say???

These points would suggest allot more than an aunt l would think?
"including an opposable thumb, short arms and legs, and forward facing eyes"

But really have no real experiance in this.
 
I'm interested in how different she is from Godinotia, a prosimian predecessor that was also discovered in the Messel Pit in Germany. Both lived at the same time (Eocene epoch) but Ida seems so much more "advanced" than her counterparts.
 
Anybody who is interested in an 'unbiased' view on the relationship of 'Ida' to humans should check out the various science blogs - particularly Laelaps and The Loom - out there. Reading through their various arguments they conclude that the specimen, while a beautifully preserved skeleton, is not as closely linked to the anthropoid line as the scientists who conducted the study might suggest. I must say that having watched the program last night and knowing some of the background information, I found the show to be quite annoying. The constant badgering about how close this specimen was to chimps and humans and totally ignoring any basal anthropoids fossils and tarsiers. All hype for a TV channel and mores the pity that Attenborough was involved.

It did keep repeating the same statements over and over. Also it seemed to me though it was aired by the BBC that it was made by another production company and he was just involved in the commentary?

Yes my overiding thoughts while watching was that the program appeared to be American-made (sorry to all of our US friends!) rather than the usual fare from the Natural History Unit of the BBC. Everything seemed to have to be spelt out repeatedly in case we missed it. Interesting that these differences can be noticeable given the amount of US culture we consume.
 
the company who made it was called Atlantis (or atlantic) or something like that. It definately wasn't a BBC production- all those differen people talking talking to the camera is not their style.....
 
People who are interested may know this already, but forget the repetitive and irritating TV show, read and download the full scientific article or the illustrations or both from PLoS ONE: Complete Primate Skeleton from the Middle Eocene of Messel in Germany: Morphology and Paleobiology

BTW when I first saw a photo of the wonderful fossil and a reconstruction of its skeleton, I immediately thought of one of the late Eric Morecambe's catchphrases - she really did have short fat hairy legs :D
