The Radiological Society of North America has published the results of a CT scan of the jaw bones of a Tyrannosaurus rex.

Scientists from Germany have identified bone disease in the fossilized jaw of a Tyrannosaurus rex using a non-destructive imaging technique based on computed tomography. Examination revealed that the famous Tyrannosaurus rex had a bone infection.

According to experts, such a method will be useful to paleontologists as an alternative to conventional methods of assessing fossils, which involve the destruction of samples. Scientists presented the results of the study at the annual meeting of the Radiological Society of North America (RSNA, Radiological Society of North America).

Tyrannosaurus was a massive carnivorous dinosaur that roamed what is now the western United States millions of years ago. In 2010, a paleontologist based in Carter County, Montana, discovered one of the most complete Tyrannosaurus rex skeletons. The remains date back 68 million years ago, which means that the dinosaur lived in the Late Cretaceous period. The fossils were sold to an investment banker who named it Tristan Otto before leasing it to the Berlin Nature Museum in Germany. It is one of only two original Tyrannosaurus rex skeletons in Europe.

Charlie Hamm, MD, a radiologist at the Charite University Hospital in Berlin, and his colleagues recently examined a portion of the lower left jaw of a dinosaur. While previous fossil research has relied heavily on invasive sampling and analysis, Dr. Hamm and his colleagues have used the Dual Energy CT (DECT) technique. tissue composition and disease processes that are impossible with single-energy CT.

On visual examination and computed tomography, scientists discovered a thickening and formation that reached the root of one of the teeth. DECT also detected fluoride accumulation, which signaled decreased bone density. Further research confirmed the weakness of one of the largest land-based predators of all time – he was diagnosed with osteomyelitis tumor.
