This pre-Inca baby was found on a barren Peruvian hillside by archaeologist combing the site before a new road is constructed

Three days into the project the archaeologist came across the cemetery, according to National Geographic News.

‘By now we have over 40 [mummy bundles] and the number increases every day.’ Guillermo Cock, a Lima-based archaeologist, reportedly told the website.

‘Given the proximity to the city and the tradition of looting in the area, we are really surprised that this is mostly undisturbed, mostly intact, mostly unlooted.

‘Only a few bundles have suffered damage by human action.’

In total the team located around 26 tombs, containing both children and adults.

The latest discovery was made close to Puruchuco-Huaquerones – the largest Inca cemetery ever excavated.

In the last 60 years researchers have examined just 10 per cent of the historic site.

So far they have uncovered 2,000 mummies, ceramics and hundreds of pieces of textile, silver, copper and gold.

The mummified skeleton has been preserved for more than 1,000 years outside Peru’s capital of Lima

As well as the baby, archaeologists also uncovered the well-preserved remains of a number of pre-Inca adult
