PremiumVIVAnews -A reptile that lived around 275 million years ago in Oklahoma is expected to become the first dinosaurs underwent cenat-cenut in his mouth. This broke the record belongs to an other land vertebrates (derived from 75 million years ago) which also had dental problems.
"These findings not only enrich our knowledge about diseases of the teeth, but also reveals the advantages and disadvantages faced by certain beings when their teeth evolved to eat both meat and plants," said Robert Reisz, a researcher from the University of Toronto Mississauga, Canada, as quoted LiveScienceof, April 21, 2011.
Just like humans, said Reisz, these findings increase the chances of infection of the mouth of the dinosaurs. In addition, there is also potential to find out the cause of death of animals.
"Comes the question, whether the dinosaurs die because of an infection?," said Reisz. "Currently we have not been able to ensure. However, the possibility of infection is one of the factors that contribute, "he said.
For example, said Reisz, toothache as it could be difficult animals to eat. "And if you are a very old like reptiles, you are potentially to be weak and then eaten by the predator," he said.
As for reptiles Labidosaurus hamatus mean is, a dinosaur that lived in the area of North America. When found, reisz and his colleagues found that there is a missing tooth and jaw bone damage in animals.
From its size, estimated the animal is an animal that is already old enough for the size of the species.
After observing the bone with a CT scan, a team of researchers found evidence of severe infections that cause the loss of teeth, cause abscesses, and lose the network in the jawbone.
"It seems this animal teeth broken and apropos don't grow teeth replacement, then going on a hole," said Reisz. "Through this hole, the bacteria enters the jaw and mouth possibility then ruin it," he said. (eh)
