How to obtain different kind of Demonbones?

Question

Recently in Tibia appeared Demonbones with different elemental attacks: Rotten Demonbone , Sulphurous Demonbone , Energized Demonbone , and Unliving Demonbone .

All of them you can find on market and problably all of them are among the loot of Zathroth Library mini-bosses.

You can find some offers on trade boards:

I was looking for some info about it in TibiaWiki, Tibiopedia and more, but each of this site give us different information. According to TibiaWiki.com.br there is no monster, which drops Energized Demonbone...

Do you have any experience with these bosses? Can you tell me which boss drops each kind of Demonbone? Any information proven with sceenshot will be appreciated :)

Hey!

I was search some info about this items cuz I never saw them before (i got curious) and this is what I found:

According with TibiaWikiBr The  Unliving Demonbone is dropped by  Ghulosh. And here is a video of one guy who drop it: https://www.youtube.com/watch?v=Wat2EL0dZJA :)

Answer 1

Are different drops from secret library bosses (Gorzindel, Lokathmor, Mazzinor, Ghulosh) , each one gives different demonbone.

Yes, and I wrote it in my question. I asked about something else - which boss drops which kind of Demonbone (screenshots are very appreciated). If you correct your answer and add a trustful source I will remove the down-vote.
