There are plans for scientists in Russia to attempt to bring woolly mammoths back from extinction.

It might all sound a bit like Jurassic Park but it's a serious project, BBC says.

Experiments will involve searching for and studying whole cells in the remains of well-preserved ancient animals, such as mammoths, to see if it is possible to clone them after they've become extinct.

The research will take place in the territory of Yakutia which is officially called the Sakha Republic, a part of the Russian Federation.

It is an incredibly large area with almost half of it lying within the Arctic Circle.

The freezing temperatures there mean a number of ancient animals have been found pretty well preserved in permafrost.

Permafrost is a thick subsurface layer of soil that remains below freezing point throughout the year.
