Collected from the bioclastic shale at the top of the Lake Neosho Shale.
General abundance: Rare
Small to medium broken pieces: Common
Some have observed a few fracture lines in this specimen.
It took some effort to free it from it's home of 302 Million Years.
Stubborn critter ... It came out in (I forget how many) pieces. However,
I was successful in putting "Humpty Dumpty" back together again!
Species: annulonodosus ?
Your identification of this "knobbed" cephalopod is correct.
