What can a spiral tell us?
How do we compare the shapes of ammonite shells? Which features are visible on the surface, and which are hidden? Where does observation end and interpretation begin?

Not only "What is it?" but "How can we find out?" Questions to begin with.
How do we compare the shapes of ammonite shells? Which features are visible on the surface, and which are hidden? Where does observation end and interpretation begin?
Faces, inclusions and growth marks. Which features can be described from a photograph, and which require examining the specimen itself?
How do we connect a specimen to the rock in which it was found? What should we record on site so we can return to this question a year later?
These are directions for future research, rather than completed studies by Dorofeya. Observations, sources and revised conclusions will be added here.
