Around twenty years ago when I was about 5 years old I went on holiday to the Isle of Wight with my family. One day when walking along the beach my father and I found a small piece of rock (approx 1.5 kilo) with what seemed to be fossil bone fragments in it. We took the rock to a place called the "dinosaur farm", a museum on the Island where a bearded chap who I seem to remember was apparently a paleontologist took a look at it, said that he believed it to be of interest and asked if they could keep it.
Being a dinosaur obsessed five year old, of course I said no and the fossil came home with me and sat on my shelf for the next twenty years and probably would've stayed there were it not for recent events. A few weeks ago I visited the Natural History Museum and was reminded of the aforementioned fossil - I decided that on my next visit home to my parents that I would find it and bring it back to London with me with the intention of trying to find out more about it.
So, my question is this: Is this something that the museum would potentially be interested in and if so who should I contact? I don't really fancy turning up with it in a rucksack and asking to see a fossil expert!
