Odobenocetops

Odobenocetops was a small toothed whale known from the Late Miocene of Peru and Chile. It had two tusks, and, in some fossils, one tusk was longer than the other.

It was an early member of the dolphin superfamily, more closely related to narwhals than dolphins, with tusks projecting towards the rear of its body. It measured about 2.1 m (6.9 ft) long and weighted between 150 and 650 kg. Its neck articulations show that it was very flexible, being able to turn its head over 90 degrees. This, coupled with its broad snout, similar to that of a walrus, suggests that it was a bottom feeder, searching for mollusks and sucking them out of their shells with a powerful tongue.
