I'm wondering if ABers should set up a fund to buy ecoman a new dictionary :-)
What search string have you been putting into your search engine? Simply putting 'palaeontology uk university' (without the quotes) brought up plenty of useful references. Here's the relevant link for the University of Leeds:
http://earth.leeds.ac.uk/earth.htm
Their requirements are a minimum of 3 A-levels, of which at least 2 should be from these: Mathematics, Physics, Chemistry, Biology, Geography or Geology. You'd need to study for 3 years for a first degree in Geological Sciences then for a further year for a masters degree in, say, Geochemistry. After this you would be eligible for consideration to join to the palaentology research programme, working towards your doctorate in this field.
Here are some further relevant links:

Hoping that something here is helpful to you.

PS: I've seen some of the mathematics involved in Earth Sciences and I'd strongly recommend taking Maths at A-level if you want to be able to make sense of some of the stuff that you'll come across. (That's not just because I used to teach A-level Maths!)
