'Jurassic Park' in real life? Researchers find possible red blood cells in 115 million-year-old dinosaur fossil

Researchers discovered structures resembling red blood cells in a 115-million-year-old dinosaur bone from Brazil, along with chemical traces of blood molecules. The bone belonged to the carnivorous dinosaur Aratasaurus museunacionali. However, some scientists, including paleontologist Mary Schweitzer, question the findings, suggesting the structures may not be actual blood cells. The discovery raises questions about how soft biological materials can survive for such long periods. Further research is needed to confirm these findings and explore molecular information preserved in fossils.
