Just for anyone visiting London....
The British Museum contains archaeological antiquities "acquired" from all parts of the globe but is particularly renowned for it's ancient middle east and Egyptian artefacts. There has been increasing contention about the circumstances under which lots of objects were obtained during the time of the British Empire. On the other hand, you could say having a load of material safely stored in London is a hell of a lot safer than anywhere ISIL are active ATM.
The Natural History Museum is where you need to go for fossils.
Both are free to visit, only special exhibitions are charged for. Great fun can be had on most Saturday mornings at the BM when, as already mentioned, "tour guide" dubs lead coach loads of Witnesses (all dressed up) around looking at artefacts that supposedly confirm Biblical events. Just follow along then drop in some choice questions about 607...
