Dinosaurs regrew their teeth every two months – a new study revelas




A dinosaur species regrew its teeth every two to three months, so says a new study. Majungasaurus, a carnivorous dinosaur that lived around 70 million years ago was a meat eating species and is believed to be regenerating its teeth every two months on an average.

Of course, almost all dinosaurs used to regenerate their teeth, but the rate at which Majungasaurus regrew them is two to 13 times faster than the other carnivorous dinosaurs that lived in its times. This study was published in a science daily recently. 

In fact, this may have something to do with the habit of these dinosaurs as they gnawed on the bones of their prey. Of course, a few animals in these days have the same habit. A few rodents gnaw on the bones as that is the only way they can imbibe some specific nutrients. However, the evolution has offered them stronger teeth, whereas the dinosaurs that lived in the past had no strong teeth.

The study was headed by Michael D’Emic, an assistant professor of biology at Adelphi University. He states that the Majungasaurus had no stronger teeth. The teeth were similar to the ones that sharks and other herbivorous dinosaurs had on them. That was obviously what made them regenerate their teeth at such a faster rate.

The study will help the scientists delve deeper into the eating habits of the dinosaurs and their current day siblings.

He holds a degree in journalism and has more than 5 years of experience in an online magazine company. He had the idea while working there but when he was quite sure about starting something on his own, he took the risk and left the job to initiate TheIdeaHive. Since then he added some team members, and along with them, he creates content as well. He mainly writes for the Science section of the site.
