What is the "easiest" way to get to the fossil fragment?

I started for Fossil Raptor yesterday, I have 920 points but still no…
Is this also one of the usual ridiculous RNG crap?

keep doing digs in Fossil fragments are usually found in locations such as [Un’Goro Crater] and [Desolace]

The easiest way to farm archeology fragments of any type, especially the ones from Cataclysm, is to farm fragments on expansions for Pandaria onwards. Once you complete research on those expansions, you receive a crate that can be exchanged for previous expansion fragments.
