Scientists have yet to find dinosaur DNA, which remains a puzzle in paleontology. Most of what we know about dinosaurs comes from their fossilized bones and teeth. These remains last a long time but tell only part of the story.
Soft tissues, however, can unlock more secrets. Rare finds like muscles, ligaments, or even skin can give us clues about how dinosaurs looked and acted. For instance, my team recently discovered preserved blood vessels in a Tyrannosaurus rex fossil, an exciting find that sheds light on dinosaur biology.
How We Made the Discovery
During my time as an undergrad in physics, I joined a research group at the University of Regina. We used particle accelerators to dive deep into fossils. Using advanced 3D imaging techniques, I noticed something intriguing in a T. rex bone—structures resembling blood vessels.
Now pursuing my PhD, I continue to apply physics to improve fossil analysis.
Meet Scotty, the Largest T. Rex
Our research focused on a remarkable specimen known as Scotty. Located at the Royal Saskatchewan Museum, Scotty is the largest and one of the most complete T. rex fossils ever found. Fossils show Scotty had a tough life, with injuries indicating battles or illness.
One rib, for instance, has a large fracture that didn’t heal completely. When bones suffer damage, they often demand more blood vessels for healing. The dense network of vessels we found in Scotty’s rib can help us understand how this dinosaur healed from its injuries.
High-Tech Imaging
Exploring fossil bones can be tricky. We need to peer inside without causing any damage. Traditional CT scans, often used in hospitals, struggle with the dense minerals in fossilized bones.
To get a clearer look, we turned to synchrotron light—intense x-rays produced at particle accelerator facilities. This technology allowed us to visualize tiny internal features, including blood vessels, in stunning detail. We discovered these vessels were preserved as iron-rich mineral casts, appearing in two layers that hint at the complex conditions they endured.
What We Can Learn
Studying Scotty’s damaged rib gives us a glimpse into how T. rexes dealt with injuries. By analyzing preserved blood vessels, we can learn about their healing processes. This knowledge might even connect to modern animals, like birds, which share ancestry with dinosaurs.
The methods we’re developing could lead to new fossil discoveries. Bones that show signs of injury or disease are likely to preserve soft tissues. With the integration of physics, paleontology, and advanced imaging, we’re starting to reveal dinosaur lives in ways we once thought impossible.
Overall, research like this isn’t just about dinosaurs; it teaches us more about evolution and adaptation. As we make new discoveries, we can better understand these ancient giants and how they overcame challenges in their lifetimes.
