No word yet of Templars, aliens or Kali-sacrificing Thuggee, but there's still much excavating to do.
And here I was thinking Douglas V Duff's On the World's Roof had conclusively located them in Tibet. Cancel Brad Pitt!
Nazi graveyards have been rediscovered deep in the Amazon rainforest during research for a book that chronicles the fanatical regime's plan to create a secret colony for a master race in the 1930s.
Totem-pole like wooden structures, standing at around 2.75m tall and with swastikas carved into them, mark the graves of the Nazis at Jari River, a northern tributary in the Amazon river.
The grave markers are believed to have been built by the Nazis but were forgotten about for decades, the UK's Daily Mail reports.
It wasn't until Jens Gluessing, author of The Guayana-Projekt: A German Adventure On The Amazon, began investigating the sites that he uncovered the wartime graves.
His book claims Hitler's henchmen believed they were destined to start a super colony in the jungle and that they were destined to settle the world like pioneers of America's wild west.
On one of the graves, an inscription says: "Joseph Greiner died here on 2.1.1936, a death from fever in the service of German Research Work."
Mr Gluessing discovered Greiner was one of three explorers sent to the jungle by the secret service to explore the region with the idea the Reich would eventually populate it.
Greiner's team sent information back to the Nazi headquarters in Berlin detailing how soldiers could live in Brazil, even though their cover story was that they were collecting wildlife samples.
In his notes to Heinrich Himmler, he said: "The two largest scantly populated, but rich in resources, areas on earth are in Siberia and South America,' he wrote to Himmler.
"They alone offer spacious immigration and settlement possibilities for the Nordic peoples."
"Amazonia" was the best place to begin colonising, he wrote.
"For the more advanced white race it offers outstanding possibilities for exploitation."
