Protobactrites is an extinct nautiloid cephalopod belonging to the Orthoceratoidea that lived in what would be Europe and Asia during the Ordovician and Silurian from 466–421.3 mya, existing for approximately 44.7 million years.[1]
Protobactrites, named by Hyatt in Zittel (1900), is an orthocerid of unknown familial affiliation[2] where it was retained by Sepkoski (2002).[3] In spite of the name, Protobactrites has no known relationship to the Bactritida
