That's the same problem with tails...

Another problem: The Uragaan Jaws have to be very, very, very heavy even for their worlds lower gravity. How can the hunter carry two of them (or more after plural quests) if you think he can barely carry one Wyvern Egg? And they are bigger than the hunter. Why can't you see them? Where does he put them after carving?

I would say the carves are just small parts of the mentioned body part. And why there can't be much more materials to be carve is maybe a quality problem. Means there are after fights and injuries only some parts that are usable for weapons and armors.
