Phragmoceras
Artwork by Franz Anthony / @franzanth
Despite being 410+ million years old, some Phragmoceras fossils have been found with traces of color patterns like stripes or zigzags. This suggests that they disguised themselves with different patterns depending on their habitat.

Phragmoceras
Look at the darker spots, could it be pigment telling us about this creatures original pattern?
The shell doesn’t seem to be intact on the other side so my guess is that this side was preserved thanks to being buried in sediment.
Found this one in Ireviken, Gotland, Sweden
Work in progress from my recent trip to Ireviken, Gotland, Sweden. Phragmoceras that looks to be in really nice shape.
The septum Horn, Phragmoceras (1957)
Phylum : Mollusca Class : Cephalopoda Subclass : Nautiloidea Order : Discosorida Family : Phragmoceratidae Genus : Phragmoceras Species : P. australis, P. mauritianus

Phragmoceras, type genus, is known by it moderately large, strongly curved, rapidly enlarging, endogastric and compressed shell with a vertically constricted aperture that opens up at either end. The siphuncle is close to the concave ventral margin, segments broadly expanded, connecting rings thick, bullettes identifiable.
