Odontoma is a common type of tumor among modern mammals.
Paleontologists at the University of Washington in Seattle during the study of the remains of a gorgonopsian, who died 225 million years ago, discovered he had odontoma — a benign tumor that develops in violation of the development of the dental system. A study published in the journal JAMA Oncology.
It is noted that odontoma is a common type of tumor among modern mammals. It was believed that these tumors began to develop in animals with the course of evolution, however, the study confirms the conjecture of scientists that it appeared long before the emergence of mammals.
“So far we have been able to detect the tumor only fossil mammals age about a million years, says author Judy Skog. — Due to this discovery we can assume that the cause of odontoma has nothing to do with the peculiarities of modern”. Scientists say that their study allows us to know the nature of diseases, which are “our legacy from the mammals”.
Odontoma is a tumor-like lesion, which is a malformation of the teeth. It violates the position of the teeth, causing pain and swelling.
