Could Cloning Bring Extinct Species Back from the Dead?

With the popularity of stories like Jurassic Park (both the book and movie version) there has been a fascination for some time now of using cloning to bring back to life species that have long been extinct.  While it sounds good in theory up until now it has been thought to be pretty hard to do due to implications of damaged or incomplete DNA.  But that may soon change.  A short CNN article this morning points us to work being done by Japanese scientists who have successfully cloned mice that have been dead and frozen for 16 years.  This research could open the possibility of eventually cloning other animals that have long been extinct.  An interesting implication to say the least.
