"Jurassic Park" was a work of fiction. Pleistocene Park is in the process of becoming fact.

A joint team of Japanese and Russian scientists arrived in the Siberian province of Yakutsk late last month to excavate a number of creatures that have been extinct for millennia -- including mammoths and woolly rhinoceroses.

They plan to extract DNA from the frozen remains, cross-breed the retrieved nuclei with the creatures' modern-day counterparts and return the resurrected dinosaurs to a vast "safari park" in northern Siberia.
