Atmospheric gases trapped in these meteorites exactly match samples measured by the Viking landers. Isotopic ratios in these gasses are unique to the location in which they formed--and completely unique. Like a fingerprint.

Whaaaat??? How do you say it came from Mars?How do you know that?

[dischordia23]

We don't have any meteorites from the Tunguska Event. Also the dog thing may have been made up at the time (1911). But very probably humans and other animals have been killed in past (like the cow from the Valera Meteorite)--just in prehistory or in remote regions where they has been poor documentation.

[Lokivoid]

"the only metorite to allegly kill something" Ummmm what about the Tunguska Event.

Just google 'lunar meteorites' for a current list.  About 66 distinct MOON meteorites (Lunaites) have been discovered so far.

Well, that's fine. But where are all the MOON meteorites? After all, the moon is much closer, and any fragments from moon metors should fall to earth. So, where are all the MOON meteorites?

[dischordia23]

Several institutions keep small specimens just for the public to touch--a slab of Lunar Basalt in the Smithsonian Air and Space Museum in DC for example. While most moon rocks are stored at the JSC and are kept in a nitrogen atmosphere, temp and humidity controlled and never directly handled to avoid any contamination.

i thnk its is a normal rock and if it is real where is the gloves and special Vestments

Let me get this right. With the closure of so many post offices, is there now an ever decreasing likelyhood of UK grounded meteorites being dubbed with disseminate titles resulting from both the multiplicative factors of widening catchment areas and the associative naming convention explained by Dr. Vic?

with METAL meteorites any moisture on your fingers could cause rust to form/discolouration over a period of time.This would be most noticeable on the acid etched pieces.Some meteorites(metal) contain elements which are more vulnerable to the effects of moisture than others.
