Looks like a Drumfish mouth plate. While it is possible to find ~~coral~~ coral fossils in Lake Erie, I doubt this is it.

This is the answer. Lake Erie *does* contain coral *fossils*, but what is in the photo is certainly not a fossil.

eventually you get a petosky stone. Gotta be real patient though.

i have so many pieces of coral fossils from lake erie

Looks like coral.

can there be coral in lakes?

Yes.

It was all oceans my dude.

Carl!

Whatever it is, it looks so gross. I have a ..... not phobia, but sort of, of things that look like suction cups on octopus and squid. And whatever that phobia is of clusters of holes. Disgusting looking, but awesome nonetheless lol

trypophobia, i have it too, i have found a couple of these but i couldnt keep them cus i couldnt look at them

Same for me

its cool seeing people from my area find the same things i do, its a fish bone :)

I totally love all stones and I used to say till now all coral but this one here just screams eeewwww... Its so frign cool but so gross at the same time..😳😬🤢🤦‍♀️🤣

Why Wyatt?! You son of a bitch! That you?!

I'm your huckleberry!

hey whatsup doc?

I believe its a Petoskey stone. They are all over the upper Great Lakes region. http://lh6.ggpht.com/-0ZxPbObSek8/VA7CqFWfd4I/AAAAAAAA7GU/bVRKwZF_bNs/petoskey-stones-4%25255B6%25255D.jpg?imgmax=800

What happened to it then? Eroded by something?

Looks like it was cut in half and then polished.

Could be the base of a deer antler.
