 When asking the ship 's computer for the engines , the Doctor , Rory , and Brian are transported to the " engine room " , a large beach on the ship which uses the waves as hydro @-@ power . Meanwhile , with Nefertiti and Riddell , Amy discovers that the ship is a Silurian ark designed to carry the reptilian humanoids to a new planet along with flora and fauna from their time period . It left Earth 65 million years ago to escape the meteor impact that wiped out the dinosaurs . The ship , however , registers no Silurian life forms left on board . After escaping from a group of pterodactyls , the Doctor , Rory , and Brian are escorted by two robots to the only human on board , a brutal man called Solomon who has been injured in a raptor attack and requires medical help . Scanning the Doctor to see who he is , Solomon is surprised that the Doctor does not appear in his universal database . Solomon reveals himself to be a lawless exotic black market trader who has raided the spaceship in order to steal the dinosaurs . Having had the robots murder all of the Silurians , Solomon was unable to take control of the ship himself and the computer defaulted to its point of origin , causing it to return to Earth . Discovering Queen Nefertiti 's identity and value , he decides to kidnap her and leave in his own ship . Though the Doctor refuses , Nefertiti agrees to go with him to save the others , despite the man 's obvious sadistic intentions towards her .
