Rare prehistoric Australian whales with razor-sharp teeth and tennis-ball eyes discovered
Recent fossil discoveries in Victoria, Australia, reveal a diverse array of bizarre, small baleen whales called mammalodontids that lived around 25 million years ago, including the newly identified Janjucetus dullardi, which was about two meters long and likely a juvenile. These whales lacked baleen and had unique features, representing an extinct branch of whale evolution that thrived during a warm, shallow sea environment before going extinct around 22 million years ago due to climate cooling.
