They announced their discovery at a Geological Society meeting in For the most part, their story was accepted in good faith. However, in new dating technology arrived that changed scientific opinion on the age of the remains Using fluorine tests, Dr Kenneth Oakley, a geologist at the Natural History Museum, discovered that the Piltdown remains were only 50, years old.

This eliminated the possibility of the Piltdown Man being the missing link between humans and apes as at this point in time humans had already developed into their Homo sapiens form. Their results showed that the skull and jaw fragments actually came from two different species, a human and an ape, probably an orangutan.
Therefore, the precision is not what it oould have been, but oertainly good enough for the present purpose. Though oontroversia1 dates on bone have been published, our recent experience indicates that ihe conclusions drawn from the present results are trustworthy Table 2. The results are satisfactory.
Even since the exposure of the hoax in and , statements have appeared in print maintaining that it is a Pleistocene fossil, considerably more ancient than the cranial bones. The indication that this mandible is a few centuries old raises the question of its origin. When Sir Wilfrid Le Gros Clark established that it was the jaw-bone of a moderrn orang-utan and therefore came from Borneo or Sumatra , it was assumed to be a zoologioal collector's piece.
Is it not very unlikely that an orang-utan jaw-bone falling into the hands of a collector would prove to be several centuries old? In fact, this is not so improbable as might be supposed.

One possibility is that the specimen was obtained from a dealer in ethnographical material. However, the chances of an ethnographical dealer obtaining such a highly treasured object directly from living Dyaks are regarded by Mr.

On the other hand, he has pointed out that a number of sub-recent bones of orang-utan, obtained in Sarawak in various circumstances, were brought back to Britain in by A. Everett and briefly described. At least one of the specimens No. Part of Everett's collection including the last specimen was preented to the British Museum Natural History.
Study reveals culprit behind Piltdown Man, one of science’s most famous hoaxes
All the orang-utan skulls and jaws listed as received by the Museum in can be accounted for; but Mr. Harrison believes that Everett brought much more material to Britain, and what became of it is unknown. Did it pass into the hands of dealers? So it seemed fortuitous when, 5 years later, Charles Dawson, a professional lawyer and amateur fossil hunter in Sussex, U. Smith Woodward and Dawson jointly presented their findings to the Geological Society of London in From their first excavation, they claimed to have discovered several pieces of a humanlike skull, an apelike mandible, some worn molar teeth, stone tools, and fossilized animals.
As more and more hominin fossils were discovered over the next few decades in Africa, China, and Indonesia, however, Piltdown Man lost its significance as a singular missing link. Further analysis revealed they were an amalgam of carefully carved and stained human and ape bones.
Piecing together the evidence
The potential perpetrators included Dawson and Smith Woodward, naturally, but also Pierre Teilhard de Chardin, a French Jesuit priest who assisted the excavation, and Martin Hinton, a volunteer who worked with Smith Woodward, among others. Isabelle De Groote, a paleoanthropologist at Liverpool John Moores University in the United Kingdom, began looking into the question in , applying modern scanning technology and DNA analysis to the original materials.
She and colleagues compared computer tomography CT scans of the mandible and teeth to known ape specimens and concluded that all these pieces originated from an orangutan.
DNA sequencing of the teeth suggested they all came from the same orangutan, which De Groote suspects the forger or forgers might have obtained from a curiosities shop. The human bones, already recognized to be from at least two individuals, revealed fewer secrets. Unfortunately, the researchers were unable to extract DNA from the bones, and radiocarbon dating failed.

Examining the CT scans, De Groote also noticed a strange, off-white putty on the surface of virtually every bone. This putty had been painted over and stained, and in some cases was used to fill in cracks and gaps that the forger accidentally created. Inside the crania and teeth, she found tiny pebbles stuffed inside hollow chambers sealed over with the same putty.
