Another London Trip: Recommendations?

[Masp]

Will be making another trip to London at the end of the month and wanted to know if anyone has recommendations for dinosaur related museums, things to see, etc. Fossil hunting may be out of the question due to the cold weather, unless there is a convenient option outside of the city nearby, or train ride away then I’m all ears (can be any material). May have to wait for a warmer holiday to go out for dinosaur hunting, Isle of Wight, etc.,  which I believe is 2-3 hours from London if I’m not mistaken. Anyhow any bit of advice would help. 
 

I have been to the Natural History Museum in London, but will be stopping by there again because of how much I enjoyed it the first time. One new stop will the be the museum in Oxford to see the beautiful Megalosaurus bucklandii, so definitely looking forward to that.
