Quick Summary

Australian scientists have identified fossilized blood in a 115-million-year-old dinosaur bone, marking the first time red blood cells and hemoglobin molecules have been chemically confirmed in such fossils. The blood was found inside a leg bone of an Aratasaurus museunacionali, a medium-sized theropod dinosaur from Brazil that lived during the early Cretaceous period. Using highly sensitive chemical analysis, researchers detected heme and other blood biomolecules, suggesting that fragile soft tissues can survive for millions of years under specific environmental conditions. This discovery could provide new insights into ancient life and even aid in the search for extraterrestrial life by indicating that delicate biological molecules might persist elsewhere in the cosmos.

Story summary

Scientists have identified what may be fossilized red blood cells in 115-million-year-old dinosaur bones, potentially rewriting our understanding of fossil preservation. The discovery was made by an international team led by Kliti Grice from Curtin University in Australia and published in the *Proceedings of the National Academy of Sciences*. The bones belong to a juvenile Aratasaurus museunacionali, unearthed in 2008 from a gypsum mine in Ceará state, northeastern Brazil. Using electron microscopy and chemical analysis, researchers found tiny round structures resembling red blood cells inside vascular canals within the dinosaur bone, along with traces of heme, an essential component of hemoglobin.

While some experts, like Mauricio Barbi from the University of Regina, find the evidence convincing but still cautious about definitive proof, Grice emphasizes that these findings provide a “mineral and molecular echo” of ancient biology. The discovery could open new avenues for studying dinosaur physiology and even contribute to searches for life elsewhere in the cosmos by demonstrating how delicate biological molecules can persist over vast geological timescales.

Why this leaning score

This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
