A discovery that shocked Japanese archaeological circles

Professor Hirayama Ren, specialized in paleontology at the School of Nutrition at Waseda University, Japan, June 22 announced the discovery of a shockwave of this country's archaeological fossils of fossil-eating dinosaurs. Largest Japanese ruler ever with body length up to 20m.

>>>Dinosaurs are much lighter than previously assumed

Five teeth dating back to the Cretaceous era 85 million years ago were identified as fossils of the same type found at the site in Iwaki City, Fukushima Prefecture, two years ago.

According to Professor Hirayama, the site of the fossils is located near the site of the excavation of amber of Kuji Amber Museum, Kuji City, Iwate Prefecture. The first tooth was found from the mud along a branch of the Osawada River on March 23.

5 fossil teeth from 2-4cm in size

Fossil pieces are 2-4cm long, 8mm diameter. These teeth have a circular cross section, appear characteristic small veins on the surface and become smaller towards the head.

From the characteristic structure of the teeth, the scientists identified this as a herbivorous dinosaur with a long tail and head. Length of head is about 60cm, body length to 20m.

This lizard-legged dinosaur is believed to belong to the Titanosaurus family, similar to the type of Nemegtosaurus found in Mongolia.

Professor Hirayama stood next to the fossil discovery

Fossil-legged lizard dinosaur species found in Japan only 6 cases so far. Fossils of the Cretaceous period (dating from 65-100 million years ago) found in this coastal area are all very rare and were first found in so many numbers.

Because herbivorous dinosaurs often gather in colonies and consume large amounts of leaves and branches, this fossil is also likely to belong to many individuals.

Near the site of the discovery of fossil teeth, archaeologists also found about 150 fossils of flying lizards, turtles and crocodiles and the Cretaceous date. Professor Hirayama's archeology team decided to conduct an additional week-long excavation in August.

Professor Hirayama expressed his hope: 'If further excavations help detect bone fossils like the first part of a dinosaur, this could become a discovery that changed the history of dinosaurs'.
