Britain's Natural History Museum bids farewell to its most famous exhibit, Dippy the diplodocus, on Wednesday after almost four decades of greeting visitors before being dismantled ahead of a national tour.

For 35 years, the huge skeleton cast, 4.25 metres (14 ft) high and 21 metres long, has been the first sight visitors see when they enter the London museum's main entrance.
