Natural History Museum: World of Wonder

Gather any nearby junior palaeontologists for this episode of the fun behind-the-exhibits doc, or for the first ten minutes at least. First we join the technicians who are fixing the malfunctioning tail of the Natural History Museum’s giant animatronic T Rex – although this isn’t as bad as his previous ailment, which was uncontrollable headbanging. Then we join another museum staff member who has a lot of real T Rex bones to sort, which means decoding which fossils belong to which dinosaur, and indeed which are plastic imitations that were previously used to plug gaps in the skeletons.

Elsewhere there are efforts to document every fauna species in Britain, a smelly guide to ambergris, and a truck arriving at the goods entrance, bursting with stuffed animals.
