Prehistoric Park (02/06) A Mammoth Undertaking

At the end of the last ice age Mammoths were already finding themselves unsuited to the changing climate, and they faced a new predator, man. When Nigel finds a dying mammoth he must battle just to keep it alive before he can return it to the present day. He wins the battle but faces a war when the mammoth refuses to eat on its return. Racing against time, Nigel and his team must pull together to find out why, before the magnificent mammoth loses all its strength and dies.
