A real live coelacanth! Well, not exactly live but definitely real - I have seen models before, but this was the first actual specimen I had ever seen.
For those interested in palaeontology, the Palaeozoological Museum Of China is absolutely outstanding. The museum is on three floors, the lower one for dinosaurs including several fully-mounted skeletons (the displays are a mix of real fossils and casts) and fossil fish, the next floor for more dinosaurs and birds, and the third for mammals. Really fascinating fossils here, although unfortunately all the signage is in Chinese apart for the scientific names.
Visited September 2013.
