The plans for the final articulation were made, and a few weeks before the opening of the
museum the skeleton was fully dried out, assembled, and ready for the transport to the
museum. Yet, there was another nasty surprise waiting: the largest entrance to the museum,
a window, was a few centimeters too low. The skeleton became wedged in whichever way
they turned it. After many attempts, they found one very special position of the skeleton in

memories of three busy and thrilling years between 2007 and 2010.
