Self-proclaimed paranormal researchers say they have proof of an "alien claw" after discovering a three-fingered bone structure in tunnels in Peru.
The Institute Inkari-Cusco, a group of "paranormal enthusiasts", said they also discovered a skull close to where they allegedly spotted the "hand".
The claims have not yet to be verified, but the researchers said they found the bones while searching caves and tunnels across Cusco in January 2016.
French researcher and explorer, Thierry Jamin, released the findings on his Facebook page on November 27.
He said, researcher Dr Edson Salazar Vivanco used x-rays and concluded that the "mummified hand" was 33 cm long, has three fingers, metallic implants.
"According to some estimates of physicians, archaeologists and anthropologists, this hand belonged to an individual whose size was maybe between 2.7m to 3m tall," Dr Vivanco said, according to a Peruvian blog.
Dr Vivanco claimed the "claw" and "skull" were genuine biological objects with real bone and skin tissues and further testing was underway.
The researchers will conduct further radiocarbon and DNA testing of the mysterious specimens in the US in early in 2017.
