Watch as Lorraine Cornish, the Museum's Head of Conservation, prepares to dismantle our Diplodocus skeleton.
The dinosaur was removed from Hintze Hall and conserved before embarking on a UK tour, which began in February 2018.
The painstaking process of dismantling the plaster and resin bones took three and a half weeks to complete.
One of the first jobs for the team was a LiDAR scan, which uses light to map the surface of a specimen.
The scan allowed scientists to learn more about the skeleton and help conservators to move the dinosaur safely around the country.
This was followed by a gentle vacuum to remove the dust from Dippy, before conservators started to remove and store the tail bones.
