Preserved in the frozen soil of Alaska are clues to an unknown land, where muskoxen and wild horses roarmed alongside woolly mammoths. Enormous American lions harried the families of mammoths, formidable in the defence of their young. The lion were more successful at hunting at bison in the snow but they were no match for the giant short-faced bear.
Un mamut lanudo, al final de la última edad de hielo, en el lejano noroeste de América del Norte, en una tierra que no existe hoy en día: Beringia.
Era una tierra de gigantes, donde mamuts lanudos vagaban junto con bueyes almizcleros, osos de cara corta gigantes retaban a enormes leones americanos, y las llanuras nevadas estaban repletas de bisontes caballos salvajes y los extraños antilopes saiga.
