The 300-million-year-old shark's teeth (nicknamed Godzilla shark) were the first sign that it might be a distinct species. The ancient chompers looked less like the spear-like rows of teeth of related species. They were squatter and shorter, less than an inch long, around 2 centimetres.

"Great for grasping and crushing prey rather than piercing prey," said discoverer John-Paul Hodnett, when he unearthed the first fossils of the shark at a dig east of Albuquerque in 2013. This week, Hodnett and a slew of other researchers published their findings in a bulletin of the New Mexico Museum of Natural History & Science identifying the shark as a separate species.

He named the 6.7-foot (2 meter) monster Dracopristis hoffmanorum, or Hoffman's Dragon Shark, in honor of the New Mexico family that owns the land in the Manzano Mountains where the fossils were found.

Hodnett said the area is rife with fossils and easy to access because of a quarry and other commercial digging operations. The name also harkens to the dragon-like jawline and 2.5-foot (0.75-meter) fin spines that inspired the discovery's initial nickname, "Godzilla Shark." The 12 rows of teeth on the shark's lower jaw were still obscured by layers of sediment after excavation. Hodnett only saw them by using an angled light technique that illuminates objects below. The recovered fossil skeleton is considered the most complete of its evolutionary branch that split from modern sharks and rays around 390 million years ago and went extinct around 60 million years later.
