It is a new kind of ancestral whale. The whale fossil with sharp teeth is 26 million years old. It appeared on the coast of Victoria, in southeast Australia.
He has big eyes, sharp teeth as blades and a compact body, designed for hunting. He was baptized as Janjucetus Dullardi. The Gentile giant that we know today is like anything. But this newly discovered ancestral whale is one of its oldest cousins.
Baby whale
The discovery offers a remarkable perspective on the early evolution of Barbadas whales. They are the giant filtering that now cross our oceans. This is what the authors of the finding, scientists from Museums Victoria say. It was a fast predator and sharp teeth, the approximate size of a dolphin. With a short snout, large frontal eyes and sharp teeth, it would have been a compact, but fearsome animal. He lived in the warm and shallow seas of the former victory.
The whale fossil with sharp teeth is a partial skull with auditory bones and teeth. It was discovered in June 2019. Victoria Museums studied it carefully. The investigation was published on August 12 at the Zoological Journal of the Linnean Society. Identify Janjucetus Dullardi as a youth baby whale. It is just over two meters long. Despite its small size, it belonged to the group known as mamiferodontids. They are the primitive whales that lived only during Oligocene, between 30 and 23 million years ago.

It is essentially a small whale with large eyes and a mouth full of sharp and sharp teeth ». He affirmed it in a statement Ruairidh Duncan. He is a doctoral student at the Victoria and University of Monash Museum Research Institute, and lead author of the study. «Imagine the version of a Barbada whale, similar to a shark. Small and deceptively adorable, but definitely not harmless ».
Advanced computerized microtomography revealed delicate structures inside the ear bones, including cochlea. He helped scientists explore how they could have perceived their environment, a crucial capacity for hunting and ocean navigation. This fossil opens a window to how old whales grew and changed. The evolution molded their bodies as they adapted to marine life, according to the authors.
