On February 12, 1947 over twenty three tons of extraterrestrial material fell over eastern Siberia. This particular specimen from that fall shows thumb-like depressions known as “regmaglypts," and ragged, twisted edges. This came from the original meteorite breaking up at a low altitude, keeping the smaller particles from enduring the high temperatures endured upon entry.
