The Russian geologist identify rock fragments of the object that exploded in Tunguska, Russia, and flattened a hundreds of hectares of forest in the region. This finding was an initial indication of the unsolved mystery for nearly a century.
Andrei E. Zlobin from Vernadsky State Geological Museum in Moscow is collected 100 pebbles that were found at the bottom of Khushmo River during an expedition in Tunguska in 1988. He guessed the stone fragments derived from meteorite that exploded over the Russia skies. Then he decided to re-visit the location of the discovery in 2008.
In the Tunguska forest, he finds three interesting rocks and named according to its shape, which is "dental crown", "whale", and "boat". The biggest rock was "whale." It has a weight of 10.4 grams with a size of 29 millimeters.

According to him, this pebble-shaped unique because it has traces of melt and wrinkles, as often found in rocks that fall from the sky. Calculation does indicate that the Tunguska explosion occurred in the air and the heat does not spread to the rock that is in the earth.

"I found the stone was cooked in a ball of fire that burned at Tunguska in 1908," said Zlobin. He sent the research result to the arXiv server that mention this finding remains to be confirmed through chemical analysis. He offers a research collaboration to the researchers from around the world to answer the cause of mystery of the Tunguska explosion.
If the rock that found by Zlobin is the meteorite fragments, then the researcher could close the investigation of the celestial body phenomena that had flattened Tunguska forests in Siberia. During this time the hard evidence like this can never be found. Many theories are used to explain this phenomenon. Some say that are an asteroids blast, comets explosion, antimatter, even the alien spacecraft blast.
The explosion which have 5 times the power of the Hiroshima bomb led to a remote forest area of 2,000 km2, it is destroyed. There was no blast hole left at the scene. But one person was reported killed by the blast wave. *** [EKA | FROM VARIOUS SOURCES | PHYSORG | LIVESCIENCE | ANTON WILLIAM | KORAN TEMPO 4221]
