TheWkly Analysis

Researchers discovered a special fin structure in a fossil of an ichthyosaur species dating back 180 million years. The fin features small grooves running lengthwise and terminating in a serrated structure at the trailing edge. This structure is formed by a combination of cartilage and skin. Such a structural form has never before been recorded in any other animal. The source article from VN also mentions unrelated discoveries like a fossil of an extinct human relative and a large carnivorous dinosaur species identified from a 125-year-old fossil.
