Images on Google earth have revealed the existence of the four-sided structure, which bears an uncanny resemblance to the famous Egyptian pyramids built thousands of years ago.
Covered by snow on each side, the find has prompted theories that what is now the snowy caps of the earth was once inhabited by humanity.
Three structures have apparently been found, two roughly 10 miles inland and the other close to the coast.
Evidence from the surrounding area indicates the climate was not as cold as it is today.
Dr Vanessa Bowman previously said: “Go back 100 million years ago and Antarctica was covered in lush rainforests similar to those that exist in New Zealand today.”
For the Antarctic pyramid, while extra-terrestrial help is also among theories, another explanation is it could be a natural phenomenon known as nunatak, which is mountain peaks which jut up just above massive glaciers.
