After a trip to the zoo, the Doctor and Martha go in search of a real life dodo, and are transported by the TARDIS to the mysterious Museum of the Last Ones. There, in the Earth section, they discover every extinct creature up to the present day - billions of them, from the tiniest insect to the biggest dinosaur, all still alive and in suspended animation.

Featuring the Tenth Doctor and Martha as played by David Tennant and Freema Agyeman in the acclaimed Doctor Who series from BBC Television.
