Can anyone ID?

[Nautiloid man]

sorry if its poor quality, I'm in class currently and it was taken on a chromebook, and sorry if I miss a space, my space key is broken.

I'm presenting these to my class and am wondering if anyone can ID them? I know one is a Goniatite, and the ammonites are cretaceous or Jurassic judging by the markings, but I really don't know about the nautilus. I'm thinking either Cimomia imperialis or Eutrephoceras.

hope to hear back soon!
