'Pahrump Hills' Region, Mars
A color mosaic taken by NASA's Mars Curiosity rover Mast Camera (mastcam) shows strata exposed along the margins of the valleys in the "Pahrump Hills" region on Mars in this undated handout photo courtesy of NASA. After 18 months of driving, scientists on September 11, 2014, announced that Curiosity had arrived at the base of Mount Sharp ahead of schedule, thanks to a somewhat serendipitous decision to take an alternative path that would be gentler on the rover's damaged wheels. Within two weeks, Curiosity will reach an outcrop of rock called Pahrump Hills, where the first drill samples of Mount Sharp real estate will be made. Reuters/NASA/JPL-Caltech/MSSS/

A human skull was discovered on Mars in October by a YouTube user with the username "Martian Archelogist." The video was uploaded on YouTube with the title "Alien Skull Found On Mars, Mars Rover 2012, Anomalies."

According to Scott C Waring of UFO Sightings Daily, the top portion of the skull looked like an ancient fossil. Scott C Waring said that the actual skull could have been replaced by minerals over the years. He said that because of being replaced by minerals, it had become entirely stone.

He explained that he collected fossil shark teeth and the teeth had been replaced by the minerals surrounding it. This resulted in the shark teeth obtaining the colour of the minerals. He noted that some of the teeth had turned black, while others turned shades of white, green and gold. He continued that the skull found in Mars changed to the same colour as its surroundings. He also said that it was a rock.

YouTube user "Martian Archelogist" had spotted the skull in one of NASA's pictures from the Mars Curiosity Rover. The YouTube video that was uploaded of the finding is about a minute and a half long and was uploaded on Oct 13. Since being uploaded, it has garnered over 1,700 views and five comments. Here is a look at the few of the comments:

B. F. De Luise: "Not a skull, the nose is missing ;)"

2AODX: "Probably have to agree with NASA. I really don't think exposed bone could sustain such exposure to the martian elements over a few hundred thousand years and not end up as dust."

The YouTube user has uploaded various videos related to the Red Planet and sticks true to its name. The last video uploaded by him is titled Mars Anomalies The Loch Ness Rock, and within a day of being uploaded, it has garnered more than 100 views.

Recently, other findings of object thay look like an animal skull, a crocodile, an alien tomb head and a naval cannon were spotted on the Red Planet. Most of the findings were made by Joe White of ArtAlienTV.
