assembling this dinosaur is like putting together a giant 3d jigsaw puzzle. there are more than 500 bones and fixings but no instruction manual. this beast measures 37 metres from the tip of its nose all the way down to its tail, and itjust about squeezes into this room with a few twists and turns along the way. the titanosaur is a cast, an exact replica of the original fossilised bones, and getting a creature like this into a 140—year—old building has been a challenge. we've had to take some of the doors off in order to get the crates and different parts of the dinosaur in, and some of the bones and the cast itself are quite heavy so we've had to reinforce our floors. that sense of awe at standing under one of the largest animals to have walked on land and trying to imagine it as a living, breathing creature is. . .yeah, it's amazing. the bones were unearthed at a ranch in patagonia in argentina just over a decade ago.
