In a revolutionary breakthrough for molecular paleontology, an international team of bioscientists has discovered chemically proven, fossilized red blood cells inside a 115-million-year-old dinosaur bone. Recovering delicate organic components from ancient geological strata is an incredibly rare feat that challenges conventional rules of preservation. While the fossilized cells have lost their original DNA strands over millions of years, the structure contains unmistakable traces of ancient heme B. This critical discovery provides paleontologists with a brand-new scientific toolkit to evaluate the metabolic rates, cellular evolution, and exact lifestyles of long-extinct prehistoric animals.
