50 years after discovering a set of teeth belonging to an undescribed species of ‘Megamouth’ related shark, scientists have determined that a new species of shark has been found. Although the species name is still to be decided, the genus is Megachasma.

The long extinct shark is related to the modern megamouth shark, which feeds exclusively on shrimp-like animals. The new species of shark swam the oceans approximately 23 million years ago. It’s discovery has been a long time coming.
