Study reveals culprit behind Piltdown Man, one of science’s most famous hoaxes
This is the home page for Piltdown man, a paleontological “man who never was”. In April of there was an extended discussion in the talk. During the discussion I checked the web and discovered that Piltdown man did not have a home page.

OAKLEY, Kenneth Page (1911-1981)
The Piltdown Man was a paleoanthropological fraud in which bone fragments were presented as the fossilised remains of a previously unknown early human. Although there were doubts about its authenticity virtually from the beginning, the remains were still broadly accepted for many years, and the falsity of the hoax was only definitively demonstrated in An extensive scientific review in established that amateur archaeologist Charles Dawson was its likely perpetrator.
In , Charles Dawson claimed that he had discovered the “missing link” between ape and man. These finds included a jawbone , more skull fragments, a set of teeth, and primitive tools. Smith Woodward reconstructed the skull fragments and hypothesised that they belonged to a human ancestor from , years ago.

Piltdown Man consists of five skull fragments, a lower jaw with two teeth and an isolated canine. The first fossil fragment was allegedly unearthed by a man digging in gravel beds in Piltdown in East Sussex, England. The man gave the skull fragment to Charles Dawson, an amateur archaeologist and fossil collector. In , Dawson did his own digging in the gravel and found additional skull fragments, as well as stone tools and the bones of extinct animals such as hippos and mastodons, which suggested the human-like skull bones were of a great antiquity.
In , Dawson wrote to Smith Woodward about his finds. The two of them—along with Pierre Teilhard de Chardin, a Jesuit priest and paleontologist—returned to the Piltdown gravels to continue excavating. They found additional skull fragments and the lower jaw. The following year Teilhard de Chardin discovered the lone canine tooth. Smith Woodward reconstructed the Piltdown man skull based on the available fossil evidence.
His work indicated the hominid had a human-like skull with a big brain but a very primitive ape-like jaw.
Oakley received a B. He was long associated with the British Museum of Natural History —69 , from which he retired in He won renown in when he played a decisive role in the exposure of the Piltdown hoax.

By the early twentieth century there was a growing need within palaeoanthropology and prehistoric archaeology to find a way of dating fossils and artefacts in order to know the age of specific specimens, but more importantly to establish an absolute chronology for human prehistory. The radiocarbon and potassium-argon dating methods revolutionized palaeoanthropology during the last half of the twentieth century. However, prior to the invention of these methods there were attempts to devise chemical means of dating fossil bone.
The invention of the fluorine dating method marked a significant advance in the quest for absolute dating in palaeoanthropology, but it also highlights interesting problems and issues relating to the ability of palaeoanthropologists and chemists to bring together different skills and bodies of knowledge in order successfully to develop and apply the fluorine dating method. Abstract By the early twentieth century there was a growing need within palaeoanthropology and prehistoric archaeology to find a way of dating fossils and artefacts in order to know the age of specific specimens, but more importantly to establish an absolute chronology for human prehistory.

1912 – Piltdown Man ‘discovered’ in England.
These included fragments of thick human skull bones, chocolate brown in colour, some fossilized hippopotamus and early elephant teeth and some crude flint tools. They had been found, he said, as a result of workmen digging gravel for paths at Barkham Manor, Piltdown, not far from Uckfield in Sussex. The gravel was an ancient river deposit, reputed to be 80 feet above the present river level, where in fact remains dating from near the beginning of the Ice Age were to be expected according to local geological opinion at that time.
Woodward agreed to join Dawson in carrying out excavations at the site at the end of May and during June

Significant evidence of early humans in the British Isles had not yet been found, and the success of the Sussex dig was a major headline-grabber. None of them showed the large brain and ape-like jaw of Piltdown Man; instead, they suggested that jaws and teeth became human-like before a large brain evolved. At that time, fluorine testing revealed that the remains were a good deal younger than had previously been claimed, closer to 50, than , years old. Later, carbon-dating technology showed that the skull was actually no more than years old.
A microscope revealed that the teeth within the jaw had been filed down to make them look more human, and that many of the remains from the Piltdown site appeared to have been stained to match each other as well as the gravel where they were supposedly found. Who was responsible for the hoax? Over the years, a number of possible suspects emerged, ranging from the most obvious—Dawson himself, either working alone or with accomplices—to the more far-fetched.
Piltdown Man Hoax Was the Work of a Single Forger, Study Says
THE most elaborate and successful scientific hoax this century that we know of must surely be that of the Piltdown Man. In at Piltdown Common in East Sussex a hugely important archaeological “discovery” was made. The fossilised skull of a creature at an intermediate evolutionary stage between ape and human was unearthed. The discovery was greeted with intense excitement in the scientific world.
It was important evidence in support of Darwin’s theory of evolution and shed light on the precise pathway by which human evolution occurred.
The famous Piltdown man, remains of a skull found in a ditch in Sussex, By applying his fluorine-dating method, Oakley confirmed that the remains were.

This year, and 60 years since the last extensive analysis of the remains led to the discovery that the Piltdown skull was a fraud, a team of over 15 analysts — including experts in ancient DNA, radiocarbon dating and isotope studies — have been assembled by Chris Stringer of the Natural History Museum in London to re-examine the Piltdown collections using modern analytical methods.
The goal is to both to establish the precise methods used to fabricate the remains, and also to determine the original sources for the specimens and clarify the motives of the forger s. The new studies, scheduled to be published next year, place in context the advances that have been made in analysis and scientific cooperation since the Piltdown finds were unearthed a century ago. No forgery of any significant fossil hominin could today escape disclosure simply because they would face a similar gauntlet of tests prior to peer-reviewed publication.
As well, the new studies will reveal the greater detail that has been obtained since the original analysis of the chemical contents of the remains led to the exposure of the fraud almost exactly sixty years ago Weiner, Oakley, and Le Gros Clark, The scientific prestige of nations and museums was based on whether they acquired and exhibited new fossil remains.
Relative Techniques. In the past, relative dating methods often were the only ones available to paleoanthropologists. As a result, it was difficult to chronologically compare fossils from different parts of the world. However, relative methods are still very useful for relating finds from the same or nearby sites with similar geological histories. The oldest and the simplest relative dating method is stratigraphy , or stratigraphic dating. It is based on the principle of superposition , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top.
This principle is logical and straightforward. However, geological strata are not always found to be in a neat chronological order.
