New Study Confirms Partial Hemoglobin Preservation in Dinosaur Remains
Bright field images are shown for vessels harvested as described in methods from (a) ostrich vessels soaked in hemoglobin solution under deoxygenating conditions, (b) ostrich vessels soaked in hemoglobin under oxygenated conditions, (c) vessels recovered from demineralized Brachylophosaurus canadensis and (d) Tyrannosaurus rex bone. Scale bars - 0.5 mm in (a-c) and 0.2 mm in (d). Image credit: Long et al., doi: 10.1098/rspa.2025.0175.

Using a technique called Resonance Raman spectroscopy, paleontologists have detected hemoglobin remnants in bone extracts from two dinosaur species, Brachylophosaurus canadensis and Tyrannosaurus rex, and confirmed that the molecule is original to these dinosaurs.
