Brachiosaurus and Monkey Puzzle

Andy travels back 150 million years to the time of brachiosaurus - a huge plant-eating dinosaur measuring 26 metres from nose to tail. His mission is to find a branch of a monkey puzzle tree - the favourite food of a brachiosaurus. But they are over 40 metres tall with no low branches - will Andy get his hands on one? And if he does, will he make it back to the museum in time before it opens?
