whale with legs fossil

Meet Peregocetus pacificus, 43 million yr old, over 3 m long, the oldest known.The study explains that is the first time such a fossil has been discovered in the Americas. It’s so interesting to see how they conquered the oceans.”.Older and smaller whale ancestors with four limbs had been discovered previously, but the latest specimen fills in a crucial gap in knowledge about how the creatures evolved and spread throughout the world’s oceans.“Other examples from this time were more fragmentary, less complete specimens,” Olivier Lambert, a scientist at the Royal Belgian Institute of Natural Sciences and first author of the study.The latest specimen proves that early whales could swim for days or possibly weeks at a time while retaining their ability to rove around on land.“Even though it could swim in the water [with] no problem, it still had little hooves on its fingers and toes,” said Park. “It’d be a lot more capable than seals at getting around on land.”.Its sharp teeth and long snout suggest the early whales may have eaten fish or crustaceans.The location of the latest discovery is also critical. The first fully aquatic whales date to around 41m to 35m years ago, filling an ecological niche left vacant when the last marine reptiles – along with the dinosaurs – went extinct 66m years ago. Fossil whales found in various rock layers. Other anatomical features, including a powerful tail and webbed feet similar to an otter suggest it was also a strong swimmer.“Whales are this iconic example of evolution,” said Travis Park, an ancient whale expert at the Natural History Museum in London, who was not involved in the latest study.
