Taking Dippy down: the first steps
Watch as Lorraine Cornish, the Museum's Head of Conservation, prepares to dismantle our Diplodocus skeleton.
The dinosaur is being removed from Hintze Hall and conserved before embarking on a UK tour, which starts in February 2018.
The painstaking process of dismantling the plaster and resin bones will take three and a half weeks to complete.
One of the first jobs for the team is a LiDAR scan, which uses light to map the surface of a specimen.
The scan will allow scientists to learn more about the skeleton and help conservators to move the dinosaur safely around the country.
This is followed by a gentle vacuum to remove the dust from Dippy, before conservators start to remove and store the tail bones.
Visit the dinosaurs
The Museum's Dinosaurs gallery is open as usual. Meet the roaring T.rex and see an Iguanodon, one of the first species ever described as a dinosaur.
