Asrul Tuanakota discovered the 15 metre-long body on Hulung Beach on Seram Island, and initially believed it to be a washed-up boat or shipping container.
Villagers have called on the government to help remove the tonnes of stinking flesh, according to the Jakarta Globe.
It is thought to be almost 50 feet (15 meters) long and 6-7 meters wide.
Some have speculated that the creature was a giant squid, while others even guessed it was an elephant. At the present moment, and due largely to the creature's size and general shape, experts anticipate it turning out to be a whale of some variety. In 2015, a creature with a long beak and furry tail was found in Russian Federation, which baffled marine experts around the world.More news: Up to 245 missing after two Mediterranean shipwrecks
