Whales teeth find
Print Edition
ANCIENT whales had extremely sharp predator teeth similar to lions, Australian scientists said on Wednesday in a discovery they believe debunks theories the mammals used their teeth to filter feed like today's gentle giants.
There are two major groups of whales — toothed creatures such as killer whales and baleen, which filter plankton and small fish from the ocean for food with special bristle-like structures in their mouths.
Using 3D scanners, Museums Victoria and Monash University palaeontologists made digital teeth models of fossil baleen whales and today's mammals from specimen collections around the world.
