Ivan Kolebaba, 2002,Ivan Kolebaba, A Contribution to the theory of the cameral mantle in some Silurian Nautiloidea (Mollusca, Cephalopoda). Bulletin of the Czech Geological Survey, Vol 77, NO 3, 1830186, 2002. included Murchisoniceras in the Palliocerida, an order of orthoconic nautiloids established by Marek, 1998, for those with incomplete connecting rings and suggestions of cameral mantle, along with other similar genera.
Morphology The shell of Murchisoniceras is generally long and straight (orthoconic). Chambers have organic deposits of calcite which provide counterbalance. Connecting rings in the siphuncle are incomplete. In life, these animals may have been similar to the modern squid, except for the long shell.
Fossil distribution Murchisoniceras is known from central Europe, Czech Republic, Bohemia.
