A new species of dinosaur has been discovered in Japan

Archaeologists have unearthed a new species of hadrosaurus (or dinosaur dinosaur) on a southern Japanese island. Details of the work were published in the journal Scientific Reports.

The wide-bodied, flat-nosed rhinos were the most common dinosaurs of the Late Cretaceous. The rocks were found mainly in the sedimentary layers of Europe, East Asia and Africa.

Derivatives have also been found in Upper Cretaceous ores in all continents except Australia and the Indian subcontinent.

One of the features of these animals was their dentures. The jaw structure allowed the dinosaurs to move their teeth in all directions, up and down, back and forth, left and right. When teeth erode and fall out, they are replaced by new ones.

The remains of the animal – the lower jaw, teeth, neck vertebrae, shoulder bones and tailbone – were found in 2004 on the 71-72 million-year-old sedimentary layer on the Japanese island of Avaji. The dinosaur, named Yamatosaurus izanagii, was distinguished by its teeth. According to Anthony R. From the structure of Fiorillo, its teeth, it can be assumed that it evolved to feed on different vegetation from other hadros. The anatomical arrangement of the rocks allowed the identification of a new species.

Yamatosaurus is also distinguished by the development of the shoulders and front limbs. According to paleontologists, this specimen is an evolutionary step in changing the gait of these animals from two-legged to four-legged. The recently discovered find provides new information about the migration of harpsichords. It is believed that these herbivores migrated from Asia via the Bering Bridge to North America, and not vice versa. When this species developed in modern Japan, the island area was annexed to the east coast of Asia. Tectonic activity divided these lands just fifteen million years ago, long before the extinction of the dinosaurs.
