Fossils and more fossils

I have a number of multiple fossils pkmn up for trade. All of them except for the Helix and Dome fossils, not sure if you can get them in x & y.

Right now I have :

3 Aerodactyl's
3 Anorith's
2 Lileep's
2 Cranidos's
4 Shieldon's
3 Tirtouga's
3 Archen's

What you want for them ?

I can trade you Omanyte and Kabuto (Helix and Dome fossil pokemon) for Lileep and Anorith
