First North American co-occurrence of Hadrosaur and Therizinosaur tracks found in Alaska
August 6, 2018
An international team of paleontologists and other geoscientists has discovered the first North American co-occurrence of hadrosaur and therizinosaur tracks in the lower Cantwell Formation within Denali National Park, suggesting that an aspect of the continental ecosystem of central Asia was also present in this part of Alaska during the Late Cretaceous.

Feel free to reply to any comment by clicking the "Reply" button.The point I drew from this is that it was quite possible to walk from Asia across the now Bering Strait into the North American continent. I think humans could do the same later on.

Much, much, much later on. The dinosuars ceased to exist somewhere around 65 million years ago, tens of millions of years before homo sapiens arrived on the scene, much less ventured into North America. Recent fossil evidence places the earliest human settlers in North America at approximatey 130,000 years ago. The geography between the late Cretaceous and the arrival of the original human immigrants simply cannot be viewed as comparable.
I would like to see why not.
