I don't rememember the Japanese crab. The roaring dinosaur is one thing that stands out in my memory, and the pterodactyl, which I think was suspended over the mummy gallery. There was, I think, a black New Look dress or suit in a glass case somewhere, in a secluded area.
In my childhood in the 1990s seem to recall seeing a T-Rex skeleton. But it was gone by the 2000s.
So at the moment the only full dinosaur skeletons you can see are at the Lapworth Museum of Geology at the University of Birmingham.
They have an Allosaurus (not a T-Rex).
And a Pteranodon.
I went in June 2018, about 2 weeks after seeing Dippy in the Gas Hall. Which was on a tour from the Natural History Museum, London.
