The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, Mya. The name Carboniferous means "coal-bearing" and derives from the Latin words carbō ("coal") and ferō ("I bear, I carry"), and was coined by geologists William Conybeare and .

Cephalopods have a long fossil record, the earliest certain cephalopod fossils are loosely coiled or straight shelled nautiloids found in the Cambrian of China million years : Mark Carnall.

Squids and octopuses are the best known of today’s cephalopods. They are rarely found as fossils because they do not have a hard shell. Nautilus is a living nautiloid cephalopod with a coiled shell. Nautiloids and their extinct relatives, including ammonites and goniatites, are.
