I have found this on a lion in south karana. Also have found several new pelts, silks and ores in the Karanas and Qeynos hills. Dropped on mobs as little as giant rats all the way to hill giants so far.
Items include crude, tattered, mangled and ruined animal pelts. Rough, tacky, sullied silks. Iron, tin, silvril and thalium ores and dusty and dry marrow.
So far no merchants found that want to buy these items. And as yet no recipes or quests found for turn in.
