scientists discovered world's first fossilized dinosaur brain tissue
British scientists say they have discovered the first example of fossilized brain tissue from a dinosaur.
Researchers made the discovery 12 years ago, but now, after in-depth analysis, it has been confirmed that the ‘brown pebble’ is a dinosaur’s brain tissue.
Finding fossilized brain tissue is extremely rare. Experts believe the dinosaur's head became buried in mud at the bottom of a bog or swamp shortly after its death.
The acidic and low-oxygen environment allowed the brain to be "pickled" and preserved. This allowed the soft tissues to be mineralized before decaying.
Scientists say the finding is most likely related to herbivore dinosaurs which lived around 133 million years ago. Researchers say the structure of the fossilized brain shows distinct similarities to the brains of modern-day dinosaur descendants, namely crocodiles and birds.
