Press Release Summary: Russian scientist found fragment of Tunguska meteorite in the
form of \"dental crown\".

Press Release Body: In June 30, 2008 we have anniversary of Tunguska event in
Siberia. Scientists try to find fragments of Tunguska space impactor during 100
years. A lot of theories were suggested for explanation of mysterious Tunguska
catastrophe in 1908. Some scientists think that it was small asteroid and other
scientists consider space impactor as small comet.

In July 1988 russian scientist Andrei Zlobin (CIAM, Moscow) found the fragment of
hard substance at the region of Tunguska catastrophe. It was the subject with
wonderful aerodynamic form which looked like \"dental crown\" (see photo). There is
well visible melting on the edges of fragment and the color of the body\'s surface
looks like rusty-brown.

Last year Zlobin\'s paper was accepted to 2007 Planetary Defence Conference at
Washington. Russian scientist described his work on Quasi Three-dimensional Modeling
of Tunguska Comet Impact. Twenty years was necessary for Zlobin before he obtained
calculative confirmation of coordinates of regions, where small heavy fragments
could be discovered. One of these regions is located not far from the place where
\"dental crown\" was found. That is why we can say strongly that one fragment of
Tunguska impactor is already found.

In 2009 Dr. Zlobin have plan to write paper about processes which produced \"dental
crown\" form of fragment. Today scientist makes mathematical model concerning these
processes. This work requires complicated calculations including numerical modeling
of gasdynamics, heat transfer and stress analysis. After this modeling we will have
more accurate information concerning parameters of Tunguska comet impact. \"I can\'t
exclude some surprise in future\" - Andrei Zlobin say.

Let us mention words of academician Dr.Sc. N.V.Vasilijev too. Vasilijev spent above
40 years of his life for investigation of Tunguska catastrophe. He said: \"It is not
excluded that A.E.Zlobin are not far from truth in something, and physics of
Tunguska phenomenon will be necessary to rewrite from position of \"clean page\" in
future. This words N.V.Vasilijev used in his final book \"The Tunguska meteorite.
Space phenomenon of 1908 summer\" [Moscow, 2004].
