Rock for the fish tank

[silentsydney]

hello, I was out walking my "kids" (4 dogs) and picked up a rock I though would look cool in my fish tank. I only looked at it a few seconds before putting it in my pack but I noticed a shell impression in it. The next day I walked around work remembering what it looked like. In my head it was big around as a quarter. In reality its about the size of a pea, lol. I cant get my camera to take photos of it to my liking, but here is the best I have.

Looks like a little bitty clam or scallop- and maybe a couple other itty bitty things too! (and no, I don't know the Latin names for those tiny things But Harry Pristis would!) Yakker

Thanks for the reply. When I was at work and saw it as quarter size in my memory, I let my mind wander. I thought it could be the only proof that some tiny marine clam was here (ohio) way back when and that it had some great value. I day dreamt that I would sell it and be able to pay off my house, or at least finish the kitchen remodel. I came back to reality and still wanted to show my "big" find off.

It is a species of Nithea. A type of yes scallop.
I'll see if I can narrow it down to a particular species.

Nice find!....makes you wonder what it was like millions or yrs. before (now that we are walking on the sea floor!

It's weird to think ohio was under sea. I found it along a trail that is along a canal. It was just lying on top of other rocks, I always thought you would have to dig for fossils.

My cousin found a piece of fossilized coral on the family farm in NW OH, and was also surprised when I told him what it was since he never knew OH was a seabed eons ago. There are fossils found in northern OH that are not from there, but were carried there from the north by glaciers. As for using it in your fish tank, you will need to boil it first since there may be bacteria in it which will kill your fish. Boiling could cause the rock to disintegrate a bit so you need to make a choice as to just keep it or use it with the fish.

I have come in to retract my earlier statement.
Considering the context or your find in Ohio, the earlier statement is not valid.
That part of the US is primarily Ordovician or Devonian. Much older than the fossil I had in mind.
I decided to post what I was thinking of so you could take a look at what I have personally found in
the Main Street formation of Tarrant Co. Texas.
Lower Cretaceous




Niethea Wrighti
Similar in structure to the "pectin" commonly found today
with the exception of flattened on one side.

I apologize for misleading you on your find.
As of now, I do not know for sure just what this is.

Amazing. . I actually picked up a couple other rocks one with another shell that looks different from the first I posted and there are other impressions that I'm not sure what made them. I'll have to try and get photos when I get home.
