I believe this sort of thing has been tried before with a mammoth, if failed. The DNA inside of the creature was far too old to actually be usable again. A cell has to split in order to create more cells, and over time the cells will become too small to split, such as the lamb they cloned successfully died at a very young age, because the DNA that was taken from the original lamb was aged somewhat, then it stayed aged and caused the lamb to die eariler. I don't want to here anything about creatures being preserved in ice either, ice may freeze them, but they die because they cannot move around and do natural body functions, therefore the whole creature dies, and if the whole creature dies, then so do the cells, because they have nothing to produce energy from.

So, in other words, it's immpossible to bring something that is dead back to life.
