"In a measure of the number of species, these animals can spread from the body and the shape of the teeth, which are influenced by their food," said Gregory P. Wilson, assistant professor of biology at Washington University. Thus was launched Redorbit.
Reportedly, the scientists examined the teeth of 41 species of multituberculate that is stored in fossil collections around the world. Scientists are using lasers and Computed Tomography (CT) to create three-dimensional images of the teeth of animals are in high resolution, which could see less than 30 microns (less than one-third the diameter of a human hair).
Scientists are also using a geographic information system software, they analyze and examine the shape of the teeth as much as necessary. The work was to determine the variation of the various surfaces of the teeth.
"If you look at the complexity of the tooth, then it will tell you information about the food. Multituberculates more likely to develop a valve on the back of their teeth, and sharp teeth at the front becomes less important, because the back teeth are more used to break down food from plants, "he said.
The researchers concluded that some of the angiosperms or flowering plants, have little effect because of the dinosaur extinction event which took Multituberculates flowering plants are growing. When the plant's spread, then the population of insect pollinators are also likely to grow and eat insect species will also benefit.
Mammals Evolve Over 20 Million Years Ago
Recent research has revealed some mammals have evolved over the past 20 million years in antiquity. These findings reveal how mammals evolved that viewed from the animal tooth development.
Paleontologist, Greogory P. Wilson of Washington University indicate a mammal named Multituberculates, a type of rodent that has a unique anatomy of the back teeth. These animals have teeth that allow them to eat any kind of flower or plant.
Extinct animals is reportedly survived the extinction in 66 million years ago, and the possibility that they are the ancestors of today's modern rodents.
