Could these mounds of sand be Australia’s very own pyramids?
While they don’t exactly rival Egypt’s mighty pyramids, it has emerged that the small structures are in fact graves of indigenous Australians.
Hundreds of the mounds can be found on the coast of Queensland, but until now their existence has been a mystery.
But a team of archaeologists who studied the structures used ground penetrating radar to ‘see’ inside, where they discovered human remains.
Dr Mary-Jean Sutton told Daily Mail Australia: ‘We don’t know how old they are. They could be 6,000 years old. They could be tens of thousands of years old.
‘We believe potentially 5,000 to 6,000 years old but they could be much, much older and potentially also younger, and we need to carry out more research to date them.’
Houses have been built around the mounds and even on top of them, with many people falsely assuming they were turkey nests.
The discovery has led to some locals worrying that they are being haunted by Aboriginal ghosts.
Dr Sutton added: ‘How do you live in this landscape when there are people buried in your garden?’
The researchers believe their discovery could lead to further knowledge of Aboriginal burial rites.
Prior to their findings, it was thought that the mounds were large nests that had been abandoned by scrub turkeys.
The birds are known to build large nests that are two to four metres across and one metre high.
