Help identify this fossil

[Declan]

I found this on a hillside where there are exposed rocks and water runoff into a narrow valley with a creek running thought. I find a lot of crinoid, shell, and coral like fossils in the creek bed, this is a bit different. The valley is located about 25miles southwest of Warrenton, MO. The valley is part of a series that dump into the Missouri River. Curious if anyone has any idea what sort of fossil this may be. The rock is .5" thick and the bottom has an inverted version of the bottom.

thank you

Cross section through a gastropod?

Cross section of part of an orthocone nautiloid.

Ya, I have a ticket for the orthocone train and I'm getting on.

Thanks for the quick feedback

Are there any good books, charts or other resources that would be helpful for identifying other fossils in central MO?

 

I found this in a creek bend near the above mentioned fossil. I am assuming that it is some sort of coral.

It is a tabulate coral.

I find it really something special that Missourian politicians give a home to their fossils.

That was all very helpful. I am glad to have a pretty good idea what both of those are now. It was exciting to stumble across something new.
