In this undated photo provided by John-Paul Hodnett are a row of teeth on the lower jaw of a 300-million-year-old shark species named this week following a nearly complete skeleton of the species in 2013 in New Mexico. Discoverer Hodnett says it was the short, squat teeth that first alerted him to the possibility that the specimen initially dubbed "Godzilla Shark" could be a species distinct from it's ancient cousins, which have longer, more spear-like teeth. The image was taken using angled light techniques that reveal fossil features underneath sediment.
