Pseudorthocerataceae is an extinct superfamily of actively mobile carnivorous cephalopod, essentially a Nautiloid, that lived in what would be North America, Europe, Australia, and Asia during the Ordovician from 490—445.6 mya, existing for approximately 44.4 million years.[1]
Pseudorthocerataceae was named by Sweet (1964). It was assigned to Pseudorthocerida by Barskov (1968); and to Orthocerida by Sweet (1964), Evans (1994) and Evans (1994).[2][3]
