Tunguska Rocks Found; It Might Be a Comet Afterall

Well it seems someone came forward to offer some of the fragments from the Tunguska explosion of 1908.

Zlobin revisited this collection in 2008 and singled out three particularly interesting rocks, nicknaming them "dental crown," "whale" and "boat" because of their features. The biggest one, "whale," weighs a mere 0.02 pounds (10.4 grams) and measures just over an inch diagonally (29 millimeters).

Zlobin says the stones have telltale signs of melting and what appear to be regmaglypts, shallow surface indentations that are sometimes created when a space rock makes a fiery entry into Earth's atmosphere.

He was supposed to have collected these specimens in 1988. That is quite a bit of a layoff between finding these rocks and putting them up for further study. Here is a picture of the rocks that the researcher said came from a comet and not a normal meteor. The one in the lower left looks like chewed bubblegum.
