Buying Apatosaurus Fossil

[Venn]

It feels like it been a month already and I am just having the worst of luck. All I need is one more piece of the Apatosaurus and my museum fossil collection is complete. I've been digging these fossils every morning and handing them to Blathers, only to have them be already collected.

So I am just willing to buy the fossil piece.
For the Apatosaurus, I already have the Head/Neck and the Torso.
So I believe I'm just looking for the tail?

If you need a fossil I have:
Mammoth Torso
Diplo Tail
Styraco Torso
Archaeopteryx

Thanks!
