Share this article

The late Cretaceous period witnessed plenty of climatic and geographical shifts. With the shifting of tectonic plates, the flora and fauna were also splitting up. During this period Hadrosaurs, Ceratopsian, Ankylosaurus prevailed in the North American region. Jeyawati, a herbivore dinosaur that belongs to the Hadrosauroid superfamily existed with other North America's dinosaurs such as Zuniceratops and Nothronychus. According to the Journal of Vertebrate Paleontology, a new species of basal Hadrosauroid was discovered in Western New Mexico. The specimen of the new species of the dinosaur consisted of partial skull bones and a few others parts of the incomplete skeleton. Douglas Wolfe, a distinguished paleontologist made this finding with the help of James Kirkland, from Utah geological survey and other volunteers. It took 13 years to complete this excavation to discover these new species from near the Zuni river region.

The most unique feature of this dinosaur is that it was duck billed which is evident from the fragile fossils of partial skull bones and broken ribs. Another unique feature is its wrinkled eye for which it is referred to as grinding-mouth, wrinkle-eye dinosaur.
