ATLANTA, Georgia (CNN)  -- The Bigfoot in the freezer is made of rubber, a Web posting asserted Tuesday.



The frozen creature reputed to be Bigfoot turned out to be made of rubber, an enthusaist reports.



The initial promoter of two hikers' claim that they found the body of Bigfoot in Georgia said he has determined that the discovery was a hoax.



The body turned out to be rubber, and the two men who claimed that they found it, Matthew Whitton and Rick Dyer, have admitted that it was a costume, said a posting Tuesday on the Web sites of Searching for Bigfoot Inc. and Squatchdetective.



The posting purportedly was written by Steve Kulls, who maintains the Squatchdetective Web site and hosts a similarly named Internet radio program, where the find was announced weeks ago.



In addition, Stanford University anthropologist Richard Klein said Monday that he was not aware he had been identified as participating in the project and would not be involved in any effort to examine the purported Bigfoot carcass.



Whitton and Dyer announced last week that they had found the body of a 7-foot-7-inch, 500-pound half-ape, half-human creature while hiking in the north Georgia mountains in June. They said they put the carcass in a freezer and had spotted about three similar living creatures.



"We were not looking for Bigfoot," Whitton, a Clayton County, Georgia, police officer, said Friday during a news conference. "We wouldn't know what we were doing if we did."



He and Dyer insisted that scientific analysis would bear out their claim.



The hoax was discovered after an "expedited melting process," Kulls wrote. "A break appeared up near the feet area ... as the team and I began examining this area near the feet, I observed the foot which looked unnatural, reached in and confirmed it was a rubber foot."



Kulls said he contacted Tom Biscardi, the self-described "Real Bigfoot Hunter" who has been searching since 1971 for the creature of legend and appeared alongside Whitton and Dyer at the news conference.



"Later that day, Tom Biscardi informed us that both Matthew Whitton and Ricky Dyer admitted it was a costume," the posting said.



Whitton and Dyer reportedly agreed to sign a promissory note and an admission of the hoax and meet with Biscardi at their hotel on Sunday. But when Biscardi went to the hotel, the two had left, Kulls wrote.



"At this time, action is being instigated against the perpetrators," the posting said, adding that the motives behind the claims were unknown. iReport.com: Do you believe in Bigfoot?



The posting said Biscardi's organization, Searching for Bigfoot Inc., "is seeking justice for themselves and for all the people who were deceived by this deception."



Kulls did not immediately return a call to the Squatchdetective contact number. A woman answering the phone at Searching for Bigfoot Inc. said Biscardi had been ill and said she was not sure when he would be returning calls.



A number listed as belonging to Matthew Whitton was disconnected as of Tuesday. Efforts to locate a phone number for Dyer on Tuesday were unsuccessful.



Dyer and Whitton failed to show up Monday for a scheduled appearance on CNN's "American Morning."



Kulls said that at the time he first interviewed Dyer on July 28 for the radio program, he suspected the duo's motive was financial. On August 12, he said, the two "requested an undisclosed sum of money as an advance, expected from the marketing and promotion."



Two days later, after signing a receipt and counting the money, Dyer and Whitton showed the Searching for Bigfoot team the freezer containing what they claimed was the body: "something appearing large, hairy and frozen in ice," Kulls wrote.



Dyer, he said, insisted on holding the news conference and told Biscardi he would not release the body unless the briefing was held Friday.



On Sunday, the research team was able to extract some hair and burn it. The hair sample "melted into a ball uncharacteristic of hair," Kulls wrote.
