Description	Flamboyant colour pattern polymorphism documented in Silurian nautiloid Phragmoceras has not been observed in any other nautiloid genus. Two specimens of P. imbricatum display different shell coloration: narrow, densely spaced longitudinal bands subparallel to the shell axis, combined with narrower transversal bands versus transverse bands running laterally obliquely to growth lamellae. Two additional types of colouration have been observed in several specimens of Phragmoceras from Gotland. If pigmentation pattern served as a form of crypsis, then the quite different types of coloration in Phragmoceras indicate different solutions of this problem. Changes in colour pattern most probably correspond with depth inhabited; nautiloids that occupied shallow water environments display rather light coloured shells in comparison with forms inhabiting a deeper water setting.
