Extinct toothless dwarf dolphin unveiled

Posted on Wednesday, 23 August, 2017 | Comment icon 3 comments
Scientists have identified an extinct species of mini-dolphin that lived over 30 million years ago.
At just over half the size of a bottlenose dolphin, this pint-sized, snub-nosed mammal was identified following the discovery of a fossilized cranium in a river near Charleston, South Carolina.

Known as Inermorostrum xenops, the species was believed to be an early offshoot of a group of cetaceans known as the toothed whales, which also include beaked whales and sperm whales.

"Inermorostrum took only four million years to evolve from ancestral whales with precisely occluding teeth into a toothless, suction feeding specialist," said study author Robert Boessenecker.

In this world of political correctness surely they should be referred to as dolphins of short stature that are dentally challenged?
