Excavated in Shimonoseki 55 years ago Dinosaur egg fossil turned out to be a new species March 16 20:36
Analysis of research groups such as Fukui Prefectural University found that fossils of dinosaur eggs excavated in Yamaguchi Prefecture 55 years ago were a new species. Egg fossils belonging to the same group as this fossil have been found in China and South Korea, providing evidence that similar or similar dinosaurs may have inhabited large parts of East Asia.
A total of 12 new dinosaur egg fossils, about 1 to 5 cm in size, have been identified as new species.
In 1965, a high school student found a friend with a friend in the early Cretaceous stratum of Shimooseki City, Yamaguchi Prefecture, between 120 and 100 million years ago.
Research groups at Fukui Prefectural University and Fukui Prefectural Dinosaur Museum have been conducting analysis using electron microscopes since 2016 four years ago. As a result, the characteristics were consistent with those found in strata of the same age in China and Korea. This indicates that they are dinosaur eggs belonging to the same group, and that they are new due to differences in shell structure and thickness.
It is said that this new species of fossils was given the scientific name of "Multifisuritus simonosekiensis", which means "Shimonoseki, a cracked egg".
The researchers note that the new egg fossils provide the first evidence that similar or similar dinosaurs may have inhabited large parts of East Asia during the Early Cretaceous.
On the other hand, the research group says that it is planning to continue excavation work in Shimonoseki City because the type of dinosaur that laid this egg is not clear.
Discoverer “I'm thrilled given the scientific name of Shimonoseki”
Yoshiharu Shimizu, who discovered the fossils, said, "I'm impressed that fossils were given a scientific name that bears the name of Shimonoseki. Through the city. "
Research group "I think Shimonoseki was a livable place"
Dr. Takuya Imai of the Dinosaur Research Institute at Fukui Prefectural University, who is the representative of the research group, said, `` Because the commonality with the fossils of eggs found in China and South Korea was seen, it was the same in Japan and the mainland It indicates that such dinosaurs existed and flourished with their offspring, which is of great significance. "
"At that time, this area was a good place to live for dinosaurs with a lot of food and few disasters. In Shimonoseki, there is a wide range of strata where dinosaur fossils are likely to be distributed. There is a possibility that bone fossils may be found if they go along, "he said.
