A reptile that lived about 275 million years ago in Oklahoma is expected to become the first dinosaurs who have cenat-cenut in his mouth. These findings belong to a record of other terrestrial vertebrates (from 75 million years ago) who also had dental problems.
â € œTemuan is not only enrich our knowledge about dental disease, but also reveal the advantages and disadvantages faced by certain beings as they evolved teeth to eat both meat and plants, â € says Robert Reisz, a researcher from the University of Toronto Mississauga, Canada, as quoted by LiveScience, April 21, 2011.
Just like humans, said Reisz, this finding increases the chances of infection of the mouth of the dinosaur. In addition, there is also potential to find the cause of death of the animal.
â € œMuncul question, whether this dinosaur died of infection?, â € said Reisz. â € œSaat we can not ensure this. However, the possibility of infection is one factor contributing to, â € he said.
For example, says Reisz, toothache like that could make it difficult animals to eat. â € œDan if you are a very old like reptiles, you really have the potential to become weak and then eaten by other predators, â € he said.
The reptile in question is Labidosaurus hamatus, dinosaurs that lived in North America. When found, reisz and his colleagues found that there are missing teeth and jaw bone damage occurs in animals.
From its size, it is estimated that this animal is an animal is old enough for the size of the species.
After observing the bone with a CT scan, the team found evidence of severe infection that causes tooth loss, causing abscesses, and loss of jaw bone tissue.
â € œTampaknya teeth broken and since this animal did not grow replacement teeth, then there is a hole, â € said Reisz. â € œLewat this hole, oral bacteria probably entered the jaw and then destroying it, â € he said.
