Cretaceous theropod footprints are among the best preserved. Chinese dinosaur expert Xing Lida says the tracks were spotted in? 2006, and were first publicly reported only in 2020 after their scientific significance was confirmed. Chinese scientists inspected the site in June 2023 and began a research project.

The area of \u200b\u200bGrallator ssatoi tracks was flooded by the Yellow River several decades ago; they were discovered during road construction.

Let us remind you that scientists from the Universities of Oxford and Birmingham found about 200 dinosaur tracks dating back 166 million years..

Focus has already talked about therapsids, the oldest mammal that lived on Earth about 200 million years ago. The predator looked like a dog with saber-shaped teeth.
