It’s thought that Dawn (known as Avgi, in Greek) was around 15-18 years old when she died.

‘Avgi has very unique, not especially female, skull and features,’ Swedish archaeologist and sculptor Oscar Nilsson explained, according to National Geographic.

The sculptor has previously brought several ancient humans back to ‘life’ through stunning reconstructions, including an 11-year-old Athenian girl named Myrtis.

But, unlike Myrtis, some of Dawn’s features are strikingly different than those common today.

‘Having reconstructed a lot of Stone Age women and men, I think some facial features seem to have disappeared or “smoothed out” with time,’ Nilsson said.

‘In general, we look less masculine, both men and women, today.’

The incredible new reconstruction was unveiled at the Acropolis Museum on Friday, by a team of researchers from the University of Athens.

But, as some have noted, ‘Dawn’ doesn’t look very happy.

She has a protruding jaw, thought to be caused by chewing on animal skin to make it into soft leather – a common practice among people of that era – and a scowling expression.

Asked why she looked angry, orthodontics professor Manolis Papagrikorakis, who created a silicone reconstruction of her face from a terracotta mould of her head, joked: ‘It’s not possible for her not to be angry during such an era.’

Dawn was possibly anemic and may have suffered from scurvy, the researchers said.

Evidence also pointed to hip and joint problems, which may have made it difficult for her to move and may have contributed to her death.

An analysis of her bones and teeth has helped researchers pinpoint around how old she was when she died, with the evidence suggesting she was aged between 15 and 18.

Discovered in a cave in 1993, the girl was named Avgi – Greek for Dawn – because she lived during what is considered to be the dawn of civilization.

Theopetra Cave, in the Thessaly region, was first inhabited about 100,000 years ago, according to the Culture Ministry.

Stone tools from the Palaeolithic, Mesolithic and Neolithic periods have been discovered, as well as pottery from the Neolithic period.

Dawn is on display at the Acropolis Museum in Athens.
