Coming to a Zoo Near You: Sabretooth Tigers and Ankylosauruses

Interesting news from CNN.com:

TOKYO, Japan (CNN) -- Japanese scientists have produced clones of mice that have been dead and frozen for 16 years -- a feat that could lead researchers to one day resurrect long-extinct species, such as the mammoth.

All they need is some organic material that has been preserved in ice for millions of years.

I find it coincidental and a little sad that this story broke the same week that Michael Chricton, who brought clones of extinct animals into mainstream American pop culture, died.
