(ORDO NEWS) — Scientists at the University of Silesia in Poland studied fossils of a 215-million-year-old Metoposaurus – an ancient large amphibian that lived during the Triassic – and found traces of the most common form of bone cancer.
According to the researchers, one of the amphibian vertebrae looked strange: the bone tissue had grown strongly, its shape and structure were abnormal.
This led scientists to believe that Metoposaurus might have suffered from some kind of bone disease. To test the theory, experts conducted tomography of the remains.
As it turned out, the bone grew both outside and deep into the vertebra.
After analyzing the tissue, the scientists concluded that the fish suffered from osteosarcoma. It is the most common bone cancer in humans.
