Some Devonian Nautiloids

i drew another picture of some nautiloids from northern Michigan 380mya. it features 3 Michelinoceras orthocerids, 3 Gomphoceras and one Acleistoceras oncocerids. most of these i have personally found fossils of within a stromatoporoid reef environment. i drew the Gomphoceras in three theoretical modes of life because no one is really sure how they lived. let me know what you think.
