Staff from the Museum's Palaeontology Conservation Unit and the Design and Installation Team are repairing damaged parts of the Diplodocus cast, which have become damaged and brittle with age.
Moulds will be taken from the dinosaur using a water-based moulding compound often used by dentists, and the missing and damaged pieces will be cast in plaster of Paris.
The replacement pieces will then be carefully colour-matched to blend with the original cast, restoring Diplodocus to its full glory. Not bad for a dinosaur that has been on show at the Museum for almost 100 years.
The dinosaur will be screened off from public view from Wednesday 11 to Friday 13 August 2004. Sorry for any inconvenience.
