    If you’ve ever been to, or lived in, or even flown over the central swath of North America, then you’ve seen the remnants of what was a uniquely fascinating environment. Scientists call it the Western Interior Seaway, and at its greatest extent, it ran from the Caribbean Sea to the Canadian Arctic.

    Thanks to Dmitry Bogdanov, Nobu Tamura, C.R. Scotese, NASA and the many others listed throughout the video for making their images available to use.

    Niche partitioning could be seen in YouTube, trying to make videos that does not have same content or else your channel will be deleted. Quite a similarity here huh?

    If all these massive carnivores could co-exist for millions of years then surely humanity can too... Right?

    Hi from Hays, KS!!!! The fish within a fish is really cool to see at the Sternberg as well as many other specimens. They even have giant animatronic dinosaurs.

    What if there were tons of soft bodied prey in the seaway that didn’t fossilize.

    In many parts of the Wasatch mountains, you can find sea shells high in the mountains. Quite amazing.

    What I would like to learn about? It is what I would like for you to learn about, it is to answer the question about the origin of life. I have seen your programs, very, very, good. Thank you so much. But as you see, you get no farther than the prokaryotes. And the viruses origin? Same deal, three or four theories without any commitment as to the truth of lifes origin. So I would suggest that life has always existed in the universe (hypothesis). Next, how about hurling a rock, heated to falling-asteroid-temperature with some heat resistant prokaryotes or similar inside the rock and please see if the prokaryotes live. Other similar experiments would be great. And you history of organelles was really good. But I need commitment from you on real answers to these harder questions. Maybe just take a position and go for it!

    South East Missouri has an abundance of sea fossils. So it extended at least to there at some point.
