An international research breakthrough has completely shattered long-held limits of fossil preservation. Scientists have successfully identified chemically confirmed traces of ancient hemoglobin and mineralized red blood cells trapped inside 115-million-year-old dinosaur limb bones. This extraordinary discovery opens up an entirely new field of molecular-level paleontology, allowing experts to analyze the true metabolism and inner physiology of extinct Mesozoic beasts directly rather than relying on bone structures alone.
