Weird toothed dolphin ancestors discovered in museum collection.

Scientists have discovered a 25 million-year-old predatory dolphin with long, sharp teeth jutting straight out from its snout in a museum collection in New Zealand. The extinct dolphin, named Nihohae matakoi, lived during the late Oligocene epoch and likely ate soft-bodied animals like squids and octopuses. The researchers believe the dolphin may have used its teeth to thrash its prey to death, similar to the behavior of juvenile sawfish. The use of these strange jutting teeth should be investigated further to understand why they evolved and why teeth like this keep appearing in different groups of animals.
