Location is in Missouri

The area is dated to the Pennsylvanian 

Formation: Probably apart of the Raytown limestone member

 

 

 

Found this weird fossil on my latest fossil hunting trip, I personally believe it to be some sort of Amminoid since the pattern seems to extend away from the shell and not towards it,  but I have only found Nautiloids in the area ( Only 2 spiral shaped specimens that do not look like this and 3 cone shaped.)

 

If anyone can Identify if this is a an Ammonoid or something else I would love to know more!

Looks like a ceratitic ammonoid/nautiloid. 

What county was it found in?

Does look like some type of an ammonoid of some sort, nice find!

Most likely Schistoceras, a goniatite.

 

The rock looks similar to oolite in the upper Winterset, but it would be really interesting if one came from the Raytown ls.

I will give some context for the area! 

 

The area is an abandoned rock pile with limestone that come from the Iola Limestone as I have found limestone containing Muncie creek nodules and a mixture of other limestone's that do not contain the signature phosphatic nodules! Sadly that means there is no accurate way of determining the stratum as each layer is piled together. I usually assume those that contain no nodules to be from some of the Raytown limestone as I have found Chondrichthyan teeth in the area outside of the matrix and inside the matrix, although they are very uncommon. Unfortunately I have not found any fern fossils in this area, unlike the ferns from a road-cut I frequent,  but I have found Calamites and petrified wood in the area.

 

 

I would like to note I have little to no experience in formation knowledge and determination so you are probably right. 

 

So far I have only been basing this information of this file I found online, and I could be interpreting it wrongly:

http://www.kgs.ku.edu/General/Geology/Franklin/03_strat2.html

 

 

 While taking a second look at the fossil in question, I now think it could be apart of the Muncie Creek limestone as I noticed the side does look like it has some properties similar to the Muncie Creek nodules in the area. I found the fossil worn out of the matrix in between some rocks that did not contain nodules and some that did.

The reason I originally thought it could be from the Raytown limestone is that I have only found spiral Nautiloids in limestone without phosphatic nodules

 and thought it could be the same for Ammonoids

Some Photos from the Area for context:

If you would like I can provide more images of the area!

 

 

PS: Thank you for the Identification, it is really helpful!

If Muncie Creek concretions are showing up in the dumped rock, it would be worthwhile to scan the ground for concretions (even on the bare 'dirt'). I did just that, and ended up with this:

This was over several outings on two sites. No promises, but the Muncie Creek is really generous when you hit it right.

You sure are finding a lot of great stuff up there in the KC area! Makes me wanna venture away from the Truman Lake area for a weekend to fossil hunt up there.

Heading up your way driving from OK to MD through KS and MO.  Would love some beta on Muncie creek and or a place for a few hours of hunting. Trying to show my students a trail of ammonites from Texas north and east as far as I can.  Thank you for whatever you might be able to share.
