Mongolian fossil is first known species of streamlined non-avian theropod dinosaur to walk on two legs
A team of researchers from Seoul National has identified the earliest known example of a streamlined, non-avian theropod dinosaur that used to walk on two legs.
They described the place where the fossils were found, what their condition was. They also explained all the features that were used to help to identify it as a new species.
The dinosaur got dented back in 2008 as part of the Korean-Mongolian International Dinosaur Expedition.
Since then, it has been enlisted with hundreds of other fossils contemplation for study by pakeontologist.
During their study, the researchers found it to be well-preserved. As it had most of its two hindlimbs, one of its forelimbs, most of its skull and most of its spinal column.
It also had a mouthful of teeth. The researchers noticed the similarities between their skeleton and in shape of many modern water birds, sleek and trim. They lived on or near the water.
The researchers also noticed another common feature that its ribs pointed toward its tail just like waterbirds.
The researchers also noted that the overall shape of the skeleton suggested very strongly that it did not use its forelimbs for walking, likely giving it a penguin-like gait.
it represented a newly discovered species. They named it Natovenator Polydontus, that means hunter that swims and has a lot of teeth.
The dinosaur was found in a rock formation dating from the Upper Cretaceous, which places it to roughly 100 million to 66 million years ago.
