A new dinosaur has been discovered and is the first of its kind



The largest dinosaur skeleton ever discovered in the country has been hiding under 72-year-old marine deposits in Mukawa, according to Hokkaido University.

First, part of the dinosaur's tail was discovered in a joint excavation by the Hobetsu Museum and the Hokkaido University Museum in 2013.

Subsequent excavations revealed a nearly complete skeleton of a dinosaur described in a study published in Scientific ". It belongs to a new genus and species of herbivorous hadrosaurus dinosaur, the university said in a news release.

Scientists called the dinosaur "Kamuysaurus japonicus". The name comes from "kamuy", the word for diet in Ainu, the language of the indigenous people of northern Japan; "saurus" meaning reptile in Latin; and "japonicus" for Japan.

What could a dinosaur look like when it was alive

  Researchers discovered a nearly full skeleton during excavations in 201[ads1]3
A group of researchers led by Yoshitsugu Kobayashi of the Museum of Hokkaido University analyzed the skeletal bones.

The dinosaur discovered is most likely an adult, according to a histological study by a research team.

It was about 8 meters long and weighed 4 or 5.3 tons, depending on whether it walked on two or four legs respectively. This is about the weight of an Asian elephant.

The frontal bone of his skull has a long front anterior platform for the nasofrontal surface, which means that the dinosaur had what some might call a duck.

The team discovered this dinosaur with three characteristics that are not shared with other biologically similar dinosaurs: the low position of the cranial bone, the short ascending process of the jaw bone, and the anterior inclination of the nerve spines of the sixth to twelfth dorsal vertebra.

What they learned from this discovery

  The corpse of Kamoysaurus, floating in the sea with two mosaics, two sea turtles and four ammonoids. and four ammonoids.
Scientists are interested in what Kamuysaurus japonicus can tell us about his treasure, a taxonomic grouping of organisms with a common ancestor – his branch of the tree of life, so that

The last common ancestors of the dinosaurs in the Edmontosaur clan were widespread in both Asia and North America. At the time, they were connected to present-day Alaska, allowing them to travel back and forth between the two continents.

Group studies also suggest that dinosaur ancestors preferred to inhabit areas near the ocean. The mid-shoreline may have played an important role in the diversification of Hadrosaurus in its evolution.
