- An international team of scientists believe they have identified fossilised red blood cells in 115-million-year-old dinosaur bones for the very first time.
- The microscopic structures were discovered in the limb bones of an Aratasaurus, a juvenile meat-eating dinosaur unearthed in Brazil in 2008.
- Researchers hailed the “landmark discovery” for challenging longstanding assumptions that biomolecules such as haemoglobin cannot survive deep time.
- Co-author Kliti Grice explained that the findings offer a direct molecular window into dinosaur metabolism, blood evolution, and ancient animal physiology.
- Experts believe the research redefines molecular preservation limits, suggesting similar traces of ancient life could potentially exist elsewhere in the universe.
