My question is why is it not possible to recreate extinct animals?

In the simplest situation, when samples of moist tissue remain 
(as is the case with the Mastodon where frozen bits have been found
in the far North), why cannot the DNA be removed from a cell and 
implanted into an ovum and carried by a related creature (elephant
in this case)?

In the case where only dry bits remain (the bones of Australopithecus or the dry skin of the Dodo or Moa or Passenger Pigeon),  are there
active or recoverable strands of DNA which could be comparably
removed and implanted into a living ovum?
