Another T. Rex Has Preserved Blood Vessels

Scientists continue to ignore
the dating implications, pushing
evolution and deep time.

 

Scotty, the T. rex discovered in 1991 and now on display at the Royal Saskatchewan Museum, has been examined with X-rays and chemical analysis. To their surprise, scientists at the Universities of Regina in Canada found “preserved blood vessels” in a rib bone. Yet they and their lackeys in the media are talking about anything but how the discovery contradicts Deep Time assumptions. Deep Time has become the Law of the Misdeeds and Perversions that cannot be altered.

Preserved Blood Vessels Discovered in a Rib Bone From the World’s Largest T. Rex Could Shed Light on How Dinosaurs Healed (Smithsonian Magazine, 15 July 2025). Reporter Sarah Kuta knows she had better not question the age. Instead, she and the University of Regina scientists who did the imaging, focus on trying to figure out how Scotty died. Why, he must have died in a battle with another male T. rex for a mate! The blood vessels only tell the Darwinians that the monster was healing from its wounds — never that he was much younger than thought.

Their research suggests Scotty’s rib had healed from a fracture, possibly an injury the T. rex incurred while battling with another dinosaur. That wasn’t a total surprise, as paleontologists have previously discovered scars and bite marks on tyrannosaur fossils that suggest mature males duked it out for territory or sexual dominance.

Scotty’s rib fracture was still healing when the dinosaur died just a few months later. This incomplete healing, the researchers write in the paper, is probably why scientists were able to see the blood vessel millions of years later.

And, of course, the entire saga must be fitted within the Darwinian paradigm.

Moving forward, the scientists hope to use similar methods to investigate other Cretaceous dinosaur fossils. With enough samples, they might someday be able to compare healing in extinct animals with healing in living species, such as birds or crocodiles, which could offer insights into the evolution of life on Earth.

Regina researchers uncover how T. rex may have healed from injuries (Sask Today, 4 July 2025). The local newspaper has nobody on staff willing to question the “experts” about how old this beast was.

X-rays produced by the CLS at the University of Saskatchewan allowed researchers to create a detailed 3D model of the dinosaur’s bone and soft tissue structures, while not damaging the 66-million-year-old fossil….

This allowed researchers to hypothesize how these structures were preserved for over millions of years.

King Charles would be very angry if one of his subjects did not believe that the T. rex evolved from bacteria. The king’s power still controls the minds of his disciples from the grave. The reporters faithfully report the words of Darwin cardinal Dr. Mauricio Barbi from the University of Regina:

“This work also provides a new way to compare how injuries healed in extinct animals, like dinosaurs, with living species, such as birds and reptiles, which helps us better understand the biology of the past, and also how life on Earth has evolved over millions of years.”

Sask. researchers examine blood vessels in fossilized rib of Scotty the T. rex (CKOM News, 5 July 2025). It would be one thing if reporters simply asked some questions about how scientists know that Scotty evolved millions of years ago. But they don’t. They swallow the standard tale whole and regurgitate it mindlessly. This report repeats the quote from cardinal Barbi verbatim. No questions asked. Scotty evolved. He died 66 million years ago. That is science.

In situ analysis of vascular structures in fractured Tyrannosaurus rex rib (Mitchell, Barbi et al., Nature Scientific Reports, 4 July 2025). Here is the open-access paper about Scotty. The authors are aware of previous soft tissue reports in dinosaurs going back 3 decades, listing a number of them in the references. In the Introduction, they say,

Investigations of “life-like” soft tissue preservation in fossils have become more commonplace, particularly in the Cretaceous period, through increased adoption of high-intensity synchrotron radiation techniques. One common type of fossil with reports of soft tissue is bone, where preserved components such as osteocytes, chondrocytes, nerves, blood vessels and collagen sheets have been described, and recently reviewed. Older publications have claimed the discovery of blood cells in dinosaur blood vessels, but these have also been reinterpreted as diagenetic alterations. In particular, the preservation of soft and pliable blood vessels has been reported in various dinosaurs (including Tyrannosaurus rex (T. rex) [7 references given]), predominantly through the pioneering work of a few research groups.

They cling to the explanation that iron stabilized the original blood vessels and blood tissues (but see 1 May 2023). They state that no original soft tissues were found in Scotty, but the preservation of blood vessels they claim are permineralized show remarkable detail, including osteons, canaliculi and Haversian canals (see Figure 2). Their methods could not detect whether the preserved blood vessel structures were still pliable, but they promise such questions “will be examined in future studies.” Given the methods, absence of evidence in this paper is not evidence of absence.

Chemical analysis of selected portions did show the presence of iron in the 3+ state, which could be indicative of either mineral replacement or of original tissue. There were some other unusual aspects of the burial site (see Fig. 3, 4): e.g.,

The site RSKM P2523.8 was found in is also abundant in plant fossils, which is unusual as plants are commonly preserved best in acidic and reducing conditions which are typically less conducive to bone preservation.

In addition to iron, calcium and manganese were detected, with traces of nickel and zinc that appear in biological tissue, and other abiological elements like lead and silicon. The absence of carbon, however, led them to believe that the sections tested chemically had been permineralized in this fossil. Evidence of original soft tissue in many other dinosaur fossils, however remains. And even if original biological molecules had been replaced in Scotty’s bones, the exquisite detail of the vessels mapped (see the Smithsonian article) raises questions about how such delicate structures could be preserved for millions of years against all the geological forces and bioturbation expected over tens of millions of years.

The method of burial also demands explanation. Scotty obviously did not lay on the ground for long after death. It must have been completely buried rapidly for microscopic details of blood vessels to be apparent today. The authors propose several episodes of burial that sound contrived:

In summary, the taphonomic path of the studied bone could be described as death, exposure to the environmental conditions causing fracturing and flaking, burial causing further compression, permineralization and fracturing, prolonged shallow burial or cyclical exhumation and reburial, and then the final deeper burial.

Are readers expected to believe that all these episodes, including “cyclical exhumation and reburial,” permitted these delicate blood vessels to remain intact for tens of millions of years? Another thing to keep in mind is that Mitchell et al. only examined small portions of a rib bone (a fractured one at that), which is small relative to the skeleton and therefore closer to the external environment. Mary Schweitzer’s team examined the center of a femur, which would be much more likely to preserve soft tissues. The non-detection of original molecules and stretchy tissue in the rib bone, therefore, cannot be considered comparable to Schweitzer’s findings.

As expected, the authors end on an evolutionary note:

It’s not a bug; it’s futureware.

While this pilot study provides some insights about the taphonomic pathway for the fractured rib of RSKM P2523.8, it also demonstrates the potential for a much larger study that tracks the bone healing/growth potential of other dinosaurs in the Cretaceous period. By examining 3D angiogenesis of different species, ages and sizes of specimens, as well as assessing different types of pathologies (fractures and varying diseases) using various synchrotron radiation techniques, one could produce a much more comprehensive recreation of ancient life and pathologies. Comparing and contrasting this to angiogenic vessels of extant relatives such as avians or crocodiles through μCT will allow a more comprehensive look at the evolution of these features in extinct species. These research questions will be explored in a future study using a similar suite of techniques used in this work. Overall, this work provides optimism for future in situ soft tissue analysis in fossil bone, which may unlock new understandings of taphonomy as well as the physiology of ancient life.

No matter the evidence, Darwin and Deep Time always survive.

Would they survive if reporters asked more questions and refused to take bluffing and evasion as an answer?
