Japanese and American scientists describe the youngest Therizinosaurus fossil from Japan and the first in Asia to be found in marine sediments. According to Phys. org, the dinosaur had long powerful claws that allowed it to "
Therizinosaurs were a large group of predominantly herbivorous theropod dinosaurs.. For the first time the remains of such dinosaurs were discovered in Asia; many therizinosaur fossils have been found in China and Mongolia, as well as in Japan.

In a new study, scientists studied a fossil that consisted of a vertebra, part of the wrist and part of the foot, which were discovered back in 2008 in the Osushinai formation.. At that time, scientists suggested that the remains belong to therizinosaurus, but it was impossible to confirm this assumption due to the lack of data for comparison..
The scientists decided to re-examine the fossils as new evidence allows therizinosaurs to be classified based on forefoot claw morphology.. This dinosaur is the third therizinosaur discovered in Japan, but the first two have not yet been described..
New dinosaur species named Paralitherizinosaurus japonicus (Japanese marine reaper reptile). Its remains have been compared to claw specimens from other similar dinosaurs.. As a result, the researchers concluded that the claws of P. japonicus were designed to hook and pull vegetation towards their mouths while "
japonicus is the youngest therizinosaur fossil found in Japan.. Their discovery indicates that such dinosaurs lived here much longer than previously thought.. Moreover, these are the first remains of a representative of this group found in the marine sediments of Asia.. This find, as well as fossils from the US, indicate that some therizinosaurs were adapted to life in coastal environments..
Earlier, paleontologists discovered the fossil remains of a flying reptile that lived on Earth 86 million years ago.. They testify that in those distant times, "
