What might this be?

I have no clue what this is, not sure how much is missing so that makes it hard along with still learning about the Goodland formation. Doesn't quite look like a gastropod or ammonite hopefully the little bumps are a clue someone recognizes.

There are some ornate gastropods in that formation... usually deformed.

That would describe this, thank you!

Came across this possible match looking at gastropods from the Sam Noble museum collection,  it's from Goodland, Turitlella seriatum granulata.

Yup. My first thought was Turritella after seeing this.
