Scientists have chemically confirmed traces of ancient blood preserved inside dinosaur bones dating back 115 million years, a discovery that challenges long-held assumptions about the durability of biological molecules. The findings, reported in the Science category, indicate that components of blood survived far longer than conventional wisdom suggested possible, offering an extraordinary window into the physiology of creatures that lived during the Cretaceous period. Researchers involved in the study said the preservation is exceptional and could prompt a reassessment of how organic material degrades over geological time.
The implications extend well beyond paleontology. According to the research team, the survival of such ancient biomolecules could yield new clues about dinosaur physiology and open fresh avenues in the search for ancient life elsewhere in the universe, including on other planets. The discovery is likely to draw intense scrutiny from the scientific community, as claims of preserved dinosaur soft tissue have historically been met with skepticism. Independent experts will now examine the chemical evidence, which, if upheld, would mark a significant advance in understanding how biological material can endure across deep time.
