Why not? No one was the wiser.
In the Natural History Museum, London, England, there was for many years the skeleton of a dinosaur ( Diplodicus I think ) which stood in the main hall, upright and articulated. The very last bone from the tip of its tail was stolen, and so it had to be replaced with a replica, made of plaster. In fact the theft took place again and again every few weeks, so often, that the Museum ordered multiple copies and kept a box of them.
