According to foreign media reported on August 5, when studying a dinosaur fossil known as "Centrosaurus", researchers at McMaster University and the Royal Ontario Museum in Canada found a severely deformed leg bone, and the latest detection found that the deformed part was actually osteosarcoma.
The researchers say this shows that even in prehistoric times, dinosaurs developed cancer.
It is understood. The fossil of "Diplodocus" unearthed in 1988 at Alberta Provincial Dinosaur Park contains a severely deformed leg bone that researchers initially thought was a trace of a compound fracture. However, the researchers then found that the malformed part was a characterization of osteosarcoma. The researchers say osteosarcoma is a serious form of bone cancer.
Paleontologist Evans said that when they visited the Royal Tyrrell Museum in 2017, they became aware of the unusual properties of the bones and decided to use modern technology to test them.
They examined the bones, made plaster casts, and performed high-resolution computed tomography scans, which took raphy (CT) scans. The scientists then cut the fossil bone into thin slices and examined it under a microscope to assess it at the bone cell level.
Through this rigorous process, scientists were able to diagnose that the calf fibula of the sharp-horned dragon had a huge malignancy larger than an apple, and that "this particular sharp-horned dragon may have been weak and lame from cancer before it died."
The discovery has previously been documented as a pathology in which dinosaurs had malignant cancers (a tumor that can spread throughout the body and severely affect health), so the discovery could help establish a link between human diseases and past diseases and allow scientists to better understand the evolution and genetics of various diseases.
