What is this stuff?

[whatnoise]

Here are a few items I ran across recently. These were given to me by my great-aunt almost 20 years ago. She passed away a few years back and I do't remember how she came to have them... she always had neat/odd things to give to her loved ones.

I was wondering if the arrowheads are real?

Anyone know what these items are?

A few close-ups of the center item...

And here are a few other random items... petrified wood, shark tooth, and what I assume to be quartz.

I don't think the arrow heads are old.

Those are cryonoied (sp) stems on the left in the second and 3rd pics.

The bottom pic has some cool stuff in it. Petrified wood, not sure about the dark fossil, but its really cool looking!

The dark one in the last pic is a megalodon sharks tooth. Very cool.

I thought so as well but there are no serrations on it and the base doesn't look right IMO

I see glass arrowheads, crinoid and coral fossils, but I can't tell what the other fossils are.
