The new shark species named ‘paradoxodon,’ or paradoxical teeth, comes from the fact that the shark appears to have emerged suddenly in the geologic record with a yet unresolved nearly 45-million-year gap from when Megalolamna possibly split from its closest relative Otodus. The international research team who based their discovery on fossilized teeth up to 4.5 centimeters (1.8 inches) tall found the teeth in California and North Carolina, Peru and Japan.

CHICAGO —(ENEWSPF)–October 6, 2016. Megalolamna paradoxodon is the name of a new extinct shark described by an international research team who based their discovery on fossilized teeth up to 4.5 centimeters (1.8 inches) tall found from the eastern and western United States (California and North Carolina), Peru and Japan.
Megalolamna paradoxodon, which measured roughly 13 feet in length, is the name of new extinct shark described by an international research team that lived during the early Miocene epoch about 20 million years ago. Megalolamna paradoxodon had grasping-type front teeth and cutting-type rear teeth likely used to seize and slice medium-sized fish and it lived in the same ancient oceans megatoothed sharks inhabited.
