Stratigraphic Range

Cambrian to Permian

Taxonomy

Phylum: Mollusca
Class: Cephalopoda

Distinctive Features

Straight
Chambers
Septa

Preservation

Manmade internal cast

Advanced notes

Nautiloids originated in the Cambrian and radiated during the Ordovician. Straight nautiloids went extinct in the Permian, but planispirally coiled nautiloids, for example the nautilus, live in the sea today.

Stratigraphic Range

Silurian to Triassic

Taxonomy

Phylum: Mollusca
Class: Gastropoda
Genus: Bellerophon

Distinctive Features

Coiled shell (planispiral)
One chamber

Preservation

Steinkern
(here an internal cast)

Advanced notes

This specimen resembles an ammonoid, in that it has a planispirally coiled shell. However note that there are no septa and the shell exists as one large chamber, allowing us to identify it confidently as a gastropod.
