Tabon Man refers to remains discovered in the Tabon Caves in Lipuun Point in Quezon, Palawan in the Philippines. They were discovered by Robert B. Fox, an American anthropologist of the National Museum of the Philippines, on May 28, 1962. These remains, the fossilized fragments of a skull of a female and the jawbones of three individuals dating back to 16,500 years ago, were the earliest known human remains in the Philippines, until a metatarsal from the Callao Man discovered in 2007 was dated in 2010 by uranium-series dating as being 67,000 years old. However, some scientists think additional evidence is necessary to confirm those fossils as a new species, rather than a locally adapted population of other "Homo" populations, such as "H. erectus" or Denisovan.
