I'm being completely serious - if you lick the end of what you think is petrified wood and your tongue kinda sticks it's fossilized bone. Bone retain its porousness when petrified.
White coral like that is dead coral and probably broke off from a storm. If it feels smooth it’s because it rolled around against sand or dirt for a while before washing ashore. No telling how old it is but it’s probably recent since it’s so clean. Old dead coral doesn’t look like that as it would have growth on it from other algae or sealife.

That's just how coral looks from it's break-off point

If you don’t mind me asking! Since we are on the topic- Do you have any ideas about this one?

So does that mean it is fossilized coral? Or would it be petrified? Sorry it’s probably a silly question but I’m still learning! I appreciate it!

That's probably just a coral skeleton. It doesn't look fossilized. The second one definitely looks like petrified (fossilized) wood.

Actually, yes. I think you are correct
