Coral? found in Keokuk IA area

Recommended Posts

CBOB

Last fall I was out near Keokuk Iowa collecting geodes during Geodefest 2016.  On a day hunt I was collecting really close to Keokuk, Iowa and Hamilton, IL and we were at a site in the Fox River.  While collecting geodes I usually will find pieces of fossil corals and throw them in the bucket.  I recently had a geode cracking party with a buddy last weekend finally cracking the geodes I collected and found this in a bucket from the trip.  I know it was collected in the Fox River and I think the river is actually right over the Missouri border.  Looks like a coral to me but wanted to see if I can get a confirmation on that or any more info.

 

Thanks!

Looks like a bivalve to me.

I agree with Tim, not a coral.

I'm confused.  I'm familiar with the Fox River in northeastern Illinois. Is there a Fox River in southern Illinois?

Rob, 

 

Looks like maybe the Fox River he mentions is in Missouri:

Thanks.  I wasn't confident with the "coral" id.  I didn't see any coral structure.

The map is correct.  I was so confused when people were calling this waterway the "Fox River". I was trying to figure out how our Fox River was all the way over there too??  But it is just the same name but different waterway all together.

Does anyone else see possible ammonite in this? Except for the third picture I would go with that as a possibility as well.

You're not the only one

Is Ephippioceras a possibility?

That was my first thought, but I just couldn't reconcile that ID with the 3rd picture. :unsure:

I agree, the third picture makes it hard to interpret. :wacko:

the type of preservation looks a bit like that in goniatites from the Namurian of the Pyrenees

I had a cephalopod vibe with it but the "bottom" of it (pic 3) throws me off as to what it is too.  ?

Could it be a clam/bivalve?

On the edge there is a seam and the ridges from the opposite sides are offset. (pic 2 & 4.)

could you clean it and take photos from each end?

Just throwing in another possibility. I don't think it's this, but it's quite possibly related to it.

 

A kind of oyster, Rastellum gregareum , found on the Vaches Noires, France, from the late Jurassic. (Those are two different specimens btw)
