Paleontologists have identified a new 25-million-year-old whale species, Janjucetus dullardi, from a fossil discovered on an Australian beach. This small, but fierce, creature with shark-like features represents an early branch of the whale family tree, offering insights into whale evolution. The discovery, made by amateur fossil hunter Ross Dullard, is only the fourth identified species from the mammalodontid group, providing crucial data on early whale adaptations and potential responses to ancient climate change. The well-preserved partial skull, including ear bones and teeth, allowed researchers to confirm this unique species.
