       Cimolichthys is a genus of late Cretaceous fish that are considered to be closely related to salmon.‭ ‬Their bodies are known to have been covered with large scutes that may have provided a degree of protection against some predatory fish.‭ ‬We are fairly certain about the diet of Cimolichthys since the remains of fish and squids have been found in association with what would have been the stomach.‭ ‬One specimen of Cimolichthys however was found with the gladius‭ (‬internal shell‭) ‬of the large squid Tusoteuthis in its mouth,‭ ‬indicating that this individual Cimolichthys died while trying to swallow a Tusoteuthis that was too big for its mouth.‭ ‬This could have cause a blockage to the gills causing the fish to suffocate.
