Subclass:	Orthoceratoidea
Order:	Orthocerida Sepkoski (2002)

Murchisoniceras is an extinct genus of actively mobile carnivorous cephalapod, essentially a Nautiloid, that lived in what would be Europe during the Silurian from 418.7—412.3 mya, existing for approximately 6.4 million years.^[1]

Taxonomy

Murchisoniceras was assigned to Orthocerida by Sepkoski (2002).^[2]

Morphology

The shell is usually long, and may be straight ("orthoconic") or gently curved. In life, these animals may have been similar to the modern squid, except for the long shell.
