Baradin Crocolisk.
These guys are needed for the daily quest Swamp Bate in Tol'Barad.
There's a constant stream of dead crocolisks , especially right after the battle has been won (or lost..) due to everyone doing the dailies, looting their corpses and going on their merry way to their next daily.
Not everyone is a skinner , so taken advantage of the looted corpses and get your savage leather with no effort!
It also works if they're spawn-killing the mobs to politely ask them to loot the bodies.
Enjoy!
