A mummified elongated skull found in Peru could finally prove the existence of aliens.

The strangely shaped head – almost as big as its 50cm (20in) body – has baffled anthropologists.

It was one of two sets of remains found in the city of Andahuaylillas in the southern province of Quispicanchi.

Spanish and Russian scientists who have examined the remains claim they are actually those of an alien

The skeletal sets were discovered by Renato Davila Riquelme, who works for the Privado Ritos Andinos museum in Cusco in south-eastern Peru.

He said that that the eye cavities are far larger than normally seen in humans.

There is a soft spot in the skull – called an open fontanelle – which is a characteristic of children in their first year of life, yet the skull also has two large molars, only found in much older humans.

Davila Riquelme said three anthropologists, from Spain and Russia, arrived at the museum last week to investigate the findings and agreed it was ‘not a human being’ and would conduct further studies.

He added: ‘Although the assessment was superficial, it is obvious that its features do not correspond to any ethnic group in the world.’

The remains of an eyeball in the right socket will help determine its genetic DNA – and clear up the controversy if it is human or not.

The second mummy is incomplete and is only 30cm (12in).

It lacks a face and seems to be wrapped in a layer as a placenta, fetal position.

The remains bear a striking resemblance to the triangular crystal skull in the 2008 Indiana Jones film Kingdom of the Crystal Skull – which turned out to be of alien origin and have supernatural powers.
