the human skull was buried in the sand.

Scientists Believe They May Have Discovered a New Human Species After Finding Ancient Skull of Child Alive 300,000 Years AgoThe fossil remains, which include a jawbone, skull, and leg bones, were discovered in Hualongdong, China in 2019.Experts were baffled that the individual's facial features did not match any known lineage, including Neanderthals, Denisovans, or Homo sapiens.This led them to suspect that there may be a missing branch in the human family tree.Interestingly, researchers say that the individual did not have a "true chin."This makes it more Denisovan-like, an extinct species of ancient humans in Asia that diverged from Neanderthals over 400,000 years ago.
