Palaeontologists found fossilised signs of dinosaur blood and collagen in a 115-million-year-old dinosaur bone. These structures were discovered in a theropod dinosaur known as Aratasaurus museunacionali. Advanced techniques identified iron-containing heme and collagen, suggesting biological materials survived long periods.

Palaeontologists found fossilised signs of dinosaur blood and collagen in a 115-million-year-old dinosaur bone. These structures were discovered in a theropod dinosaur known as Aratasaurus museunacionali. Advanced techniques identified iron-containing heme and collagen, suggesting biological materials survived long periods. Researchers believe rapid burial in low-oxygen conditions contributed to preservation. This discovery opens new avenues for understanding dinosaur biology beyond skeletal remains.
