According to archaeologists, the way the "gay caveman" was buried suggests he was considered more effeminate than other male peers, the Daily Mail reports.
The skeleton of the early homo-sapien was recently unearthed during archaeology excavations in the Czech Republic, and is believed to date back to between 2900 and 2500 BC.
Experts say during that period, men were traditionally buried lying on their right side, with the head pointing towards the west, alongside weapons, hammers and flint knives.
In this case, the man was on his left side, his head facing west, and surrounded with household jugs, not weapons — usually symbolism reserved for women.
The team carrying out the dig said because of the layout of the grave, it was likely to indicate the person was a transvestite or "third gender", which is sometimes associated in Western Culture with being gay.
The late Stone Age man was also buried with an oval, egg-shaped container, usually associated with female burials.
"From history and ethnology, we know that people from this period took funeral rites very seriously so it is highly unlikely that this positioning was a mistake," said lead researcher Kamila Remisova Vesinova.
"Far more likely is that he was a man with a different sexual orientation, homosexual or transvestite. What we see here does not add up to traditional Corded Ware cultural norms."
Another member of the archaeological team, Katerina Semradova, added: " We believe this is one of the earliest cases of what could be described as a transvestite or third-gender grave in the Czech Republic."
