Researchers report finding mineralized structures resembling red blood cells and chemical traces of heme in the 115-million-year-old leg bone of a Brazilian Aratasaurus, evidence that could expand studies of dinosaur biology and fossil preservation.
An international research team led by Curtin University has for the first time uncovered unequivocal evidence of fossilized red blood cells and amino acids of collagen, reshaping our understanding of fossil preservation and molecular longevity in deep time.
A dinosaur that breathed its last breath in the middle of the Cretaceous may have left behind more than a mould of its bones, with a study reporting the astonishing discovery of mineralized blood cells inside the theropod’s 115-million-year-old remains.
Chemical tests on Aratasaurus bone identify presence of heme, the organic compound that allows haemoglobin in blood to carry oxygen around body It could be the opening of a Jurassic Park rip-off: scientists examining ancient dinosaur bones find what appear to be fossilised red blood cells, and trace…
By Taylor Nicioli, CNN (CNN) — Traces of prehistoric blood could reveal unprecedented clues about dinosaur biology, but they’ve been notoriously difficult to confirm. Now, researchers studying a 115 million-year-old dinosaur bone say they’ve found the strongest evidence yet of red blood cells in a f…
