Silurian Warrior Mask
From Tardis Wiki, the free Doctor Who reference
Silurian Warrior Masks, also known as Silurian Masks (GAME: Lost in Time) and at one point by the Eleventh Doctor as Tribal masks (GAME: The Mazes of Time) were protective masks worn by Silurian Warriors.
These masks resembled the face of the Silurians seen on prehistoric Earth. (COMIC: Supremacy of the Cybermen) The faces of the late Silurian subspecies who wore the masks, however, were more reminiscent of humans. (PROSE: The Monster Vault)
Elite warriors forgone the use of masks, as the Doctor observed, their skills in combat made them feared even without a mask. (GAME: The Mazes of Time)
