Hmm. Yeah, you're right. I swear I heard Titanium as an example in some Science Channel documentary one time, but it must have been a different element.

Well, yeah, but given that when the universe first formed there were no structures like atoms, all atoms that exist today had to have formed somehow. Titanium can't form in star fusion because it's too heavy, so all titanium that exists today had to have formed in some other process, like a supernova. Some Titanium likely "lived" through multiple supernovae to get to where it is today, in asteroids or on the Moon, etc.

If I remember right, elements heavier than iron can't be created in the normal fusion process that happens at the center of stars. Titanium is heavier than Iron. Titanium is created in supernovas, which do have the ability to form elements heavier than iron. So, maybe that's what you were thinking of?

Edit: I misremembered that. Iron is the heaviest element a star can fuse, but Titanium is lighter than Iron so it can be fused in stars. If I figure out why I was thinking Titanium was a supernova only element, I'll report back.
