Mysterious sand mounds in Australia are burial sites built before Egypt's pyramids
Local indigenous people have also expressed fear that these structures may be surrounded by ghosts.
While a lot has been discovered about human history over the past several decades, there are still some mysteries that remain unsolved. As experts still try to figure out what details about structures like the Stonehenge, similar cases keep surfacing from time to time.
Sand mounds in Australia were once thought of as abandoned bird nests but it has now been revealed that they were actually graves. The burial sites of indigenous Australians are actually found to have been built before Egypt’s pyramids.
Hundreds of such mounds have been located on a 60 kilometre stretch on the coast of Mapoon. Local indigenous people have also expressed fear that these structures may be surrounded by ghosts.
Some of the mounds which may contain human remains are up to four metres high. Archaeologists used ground penetrating radar to catch a glimpse of burial practices inside the earth.
Stones, corals and spears have also been found in some mounds which are built on burnt surfaces. This could change the understanding of indigenous burial rites in Australia.
