|Hi teevee; Are you saying that the frogs come back to life??? Hard to believe. I have to look that up...|
"After being frozen for years many metres down in the permafrost, the Siberian salamander can thaw out, get up and run off. Local legend has it that some may have been frozen alongside mammoths in the Pleistocene age – and still come to life when thawed out. Much as scientists would love to have a specimen of DNA from an organism that lived so long ago, the legends are unlikely to be true. Although frozen salamanders have been found in layers of ice 14 metres down, which were deposited in the Pleistocene age more than 12 000 years ago, they probably fell to this depth much later, through deep cracks in the permafrost."
P.S. On the subject of the instantly frozen mammoths, the places where rivers deposit stuff is on the in side of turns. And they erode on the out side with the result that rivers end up with bows. These eventually pinch off and make lakes, and in cold regions, without the moving water of the river, the lakes freeze to permafrost. These are what are mined for fossil ivory.
