Although politics and societal upheavals tend to hog most of the limelight in current affairs, there is also another revolution underway in the field of paleontology. This time, a group of scientists at the University of Regina unveiled an exciting development linking two seemingly unconnected fields \u2013 the discovery of blood vessels in the fossils of the Tyrannosaurus rex.<\/p>\n\n\n\n
The discovery was made with the use of high-energy synchrotron X-ray technology that employs highly concentrated light beams produced in particle accelerators to see through the bones of “Scotty,” the nickname for an especially complete and largest-ever unearthed specimen of Tyrannosaurus Rex. However, while the remains of Scotty are very massive and robust, what has been discovered about him in April 2026, as reported in Scientific Reports, is truly delicate.<\/p>\n\n\n\n
Employing non-destructive 3D imaging techniques, scientists identified a series of iron-containing structures that have remained embedded in a healing fractured bone dating back 66 million years ago. The iron-containing structures are remnants of blood vessels, which existed during Scotty’s lifetime due to a certain chemical transformation in the process of fossilisation.<\/p>\n\n\n\n
Dinosaurs have only been known for about one hundred years through the “hard” tissues of their bodies: skeletons and teeth. While they provide information on appearance or diet, they do not tell much about internal processes. The discovery of soft tissue traces such as blood vessels is a rare opportunity to examine a dinosaur\u2019s metabolism and its ability to heal from wounds.<\/p>\n\n\n\n
The discovery of these blood vessels in the healing ribs indicates that T. rex was equipped with an effective blood supply that helped react quickly to injuries. In addition to other research results, the fact confirms that T. rex was not an indifferent cold-blooded lizard but a dynamic creature with complicated biological systems similar to modern birds.<\/p>\n\n\n\n
Nevertheless, despite all the hype around this discovery, scientists have not failed to keep expectations in check when it comes to “Jurassic Park”-style scenarios. Indeed, even though the vessels were able to survive the tens of millions of years since their formation, the actual DNA was not. This is because DNA is a rather delicate chemical structure which degrades relatively rapidly; it was thus confirmed by the scientists that even though the vascular architecture exists, DNA is out of their reach.<\/p>\n\n\n\n
Nevertheless, the methodology applied during this study offers opportunities for studying museum exhibits around the world. If blood vessels are found in Scotty, there might also be others hiding within hundreds of different fossils in museums.<\/p>\n\n\n\n
The revelation that there were blood vessels found in a fossil that is 66 million years old proves the fact that there are still many secrets about our planet that are able to turn the pages of history upside down. The closer we get to looking inside our planet through the microscope, the better we will understand the dinosaurs as a real biological life form.<\/p>\n","protected":false},"excerpt":{"rendered":"
