I found this specimen in my travels to Indonesia is this a tree trunk or a mammoth ivory?

Welcome to tnet!

Your item in question does show some type of a ring growth. It may be petrified wood or it may also be a petrified tooth section. Hard to tell.

Looks like ivory.

Not sure on my response. Can you please show us the other side. Cross section side.

I do not see the Schreger lines (cross hatched lines) so I do not think this is Mammoth, Mastodon, and any other mammuthus don't know if that is the correct word for any type of elephant like extinct mammal.

Can you post more photos from different angles?
