Traces of ancient blood found in 115 million-year-old dinosaur fossil, new study claims
Chemical signatures found in a Brazilian dinosaur bone may be preserved red blood cells, a new study suggests, but not all experts agree.
Microscopic structures resembling red blood cells and chemical signatures of heme have been discovered in the fossilized bones of a 115 million-year-old dinosaur from Brazil, according to a new study. The findings, published in the journal PNAS, suggest this is the oldest evidence of blood-related material in a dinosaur fossil. However, some experts remain skeptical about the team's conclusions, arguing that the shape of the structures does not match those of reptilian red blood cells.
