New evidence suggests tiny prehistoric whales only lived in one place

An ancient whale species, Janjucetus dullardi, has been discovered from fossils unearthed along Australia’s Surf Coast.
Named after local resident Ross Dullard, who found the fossil fragments in 2019, the species roamed the seas of what is now Victoria approximately 26 million years ago.
Unlike modern filter-feeding whales, Janjucetus dullardi was a fast, sharp-toothed predator, about the size of a dolphin, with large eyes and a compact body.
The discovery, based on a partial skull and ear bone, offers significant insights into the early evolution of marine mammals, particularly baleen whales.
This find is the third mammalodontid species from Victoria and the first to preserve detailed teeth and inner ear structures.
