In a groundbreaking revelation, scientists have unearthed evidence of damaged hemoglobin in the blood vessel-like structures of dinosaur fossils. This remarkable discovery has emerged through the application of an innovative spectroscopic technique, offering a potential resolution to the longstanding debate surrounding the existence of dinosaur soft tissue.
Unveiling Ancient Mysteries
Two decades ago, paleontologist Mary Schweitzer and her team uncovered elastic vessel-like structures in a 68-million-year-old Tyrannosaurus rex femur from Montana, sparking intrigue within the scientific community. Despite subsequent findings in another dinosaur specimen, skepticism persisted among some experts regarding the preservation of soft tissue over millions of years.
