115-million-year-old Aratasaurus bone reveals evolutionary clues to dinosaur hematology, challenging assumptions about prehistoric physiology and fossil preservation

Indigenous knowledge systems, such as those of the Aboriginal Australians or Mesoamerican civilizations, historically documented animal physiology through observational and empirical methods long before Western science formalized paleontology. For example, pre-Columbian scholars may have interpreted fossilized bone structures as indicators of species behavior or ecological roles, offering alternative frameworks for understanding prehistoric life. The absence of these perspectives in mainstream paleontology reflects a broader erasure of non-Western contributions to scientific inquiry. Additionally, Indigenous oral histories often describe ancestral beings with traits that align with paleontological findings, such as the *Rainbow Serpent* in Australian Dreamtime, which embodies deep-time ecological knowledge. Incorporating these traditions could enrich the study of dinosaur physiology by providing cultural context for biochemical discoveries.
Text: The discovery of heme in an 115-million-year-old *Aratasaurus* bone is not merely a scientific curiosity but a systemic disruption to how we understand prehistoric life, fossilization, and the biases inherent in paleontological research.
By restoring historical precedents like the 19th-century 'Bone Wars,' we see how speculative claims about dinosaur physiology have repeatedly shaped the field, often driven by competitive rather than evidence-based motivations. The absence of Indigenous and marginalized voices in this narrative obscures alternative frameworks for interpreting fossils, such as the Aboriginal Dreamtime stories that embed prehistoric beings within spiritual and ecological continuities. Meanwhile, the structural underfunding of paleobiochemistry—compared to the glamour of dinosaur morphology—highlights how institutional priorities distort scientific progress, favoring visible over molecular evidence. The heme discovery also challenges Western-centric models of oxygen transport, inviting cross-cultural comparisons with concepts like *qi* that view life force as dynamic and interconnected. Future modelling must integrate these dimensions to avoid repeating the same reductionist pitfalls, ensuring that paleontology becomes a truly interdisciplinary and inclusive field. Ultimately, this finding is a call to rethink not just dinosaur physiology, but the very foundations of how science is conducted, funded, and interpreted.
