Rolfodon is an extinct genus of shark in the family Chlamydoselachidae. It is closely related to the extant frilled sharks in the genus Chlamydoselachus, which it can be differentiated from by tooth morphology. It is named after late Canadian paleontologist Rolf Ludvigsen.[1]
The earliest fossil teeth of Rolfodon are known from the Late Cretaceous (Campanian), and it is one of two genera of Chlamydoselachidae along with Chlamydoselachus known to have survived the Cretaceous–Paleogene extinction event, although unlike Chlamydoselachus, Rolfodon went extinct by the Late Miocene. Remains are known from worldwide, including Canada, Austria, New Zealand, Angola, Ecuador, and Antarctica. As with modern frilled sharks, Rolfodon appears to have been specialized to deep-water environments.[1]
