Amaltheus homeomorphs?

[Fossil fiend]

Hello everyone,

Was wondering if someone could provide me with a few Homeomorphs for Amaltheus. I'm doing my degree's third year project and trying to find these and explain the differences is driving me mad. Any help would be appreciated.

 

[Architeuthoceras]

Maybe Dorsetensia
Also try Darellella and Reynesella, they look comparable. Amaltheus has a similar shape and ribs, but the keel is serrated.
Deja vu
Homeomorphy is still kind of abstract to me so I hope this helps

And to TONMO
