A United States study on Wednesday explained that the long-necked plant feeding dinosaurs that wandered the Earth 150 million years ago undergone evolution a substantial way of fixing broken teeth which are known to be new ones to grow.
Scientists examined the fossils of two of the largest herbivores known to have lived in North America - Diplodocus and Camarasaurus – at the same time explored that they grew fresh smiles every six weeks or so. Furthermore, the research in the journal PLoS ONE said that they carried several spares, much like human adult teeth that descend after baby teeth fall out.
Researcher Michael D'Emic from Stony Brook University in New York explained with close approximation of 30m a sauropod dinosaur would have had a fresh tooth in each position about every one to two months sometimes less. Accompanied by vivid impression, sauropods took a quantity over quality advances to making teeth, opposite the advances taken by large animals mammals this present day.
