A Dino With Grinding Mouth and Wrinkle Eyes

In University of Pennsylvania doctoral candidates and a team of paleontologists, has described a new species of Dinosaur  with an incomplete skeleton. It was found in western New Mexico. The new species, Jeyawati rugoculus was found from rocks that conserves a swampy forest ecosystem that found near the shore of a vast inland sea.It was found before 91 million years ago.

The specimen was kept under a Paleontological Resource. They  are used   by the U.S. Bureau of Land Management for the study  provided by the Paleontological Society, the Western Interior Paleontological Society and the University of Nebraska Undergraduate Creative Activity and Research Program.

The dinosaur, whose name describes to mean "grinding-mouth, wrinkle-eye," was most likely an herbivore that consumes the ferns and conifer trees found as fossils in the same rock layer. A basal hadrosauroid, the find has partial skull bones, several vertebrae and fragments of the ribs.
Jeyawati is a  type of the duck-billed hadrosaurs, which were abundant across the Northern Hemisphere for much of the Late Cretaceous Epoch, between 80 and 65 million years ago. Jeyawati has features of the teeth and jaws that preclude it from   a fully-fledged hadrosaur.
