NOVA's Arctic Dinosaurs
Last Tuesday, a night ago, NOVA had Arctic Dinosaurs.
It was a welcomed relief from the nasty science fiction that NOVA seems to be dishing out alot in recent years with its String baloney and Black Hole baloney and Big Bang baloney. So we had a NOVA that was decent with Arctic Dinosaurs. And I learned something new about plants in that toothed leaves means cold climate. But I think this program made too much fuss over the fact of dinosaurs in the arctic. The arctic as the botanist pointed out was more temperate climate. But I think they exaggerated the idea of migration would have been strenous. They showed a picture of the southern coast of Alaska as a temperate rainforest. So if the botanist who concluded the Arctic north was temperate and had collected fossils of plants at the southern tip of Alaska and found those to be subtropical or approaching subtropical. That it would have been quite feasible that the dinosaurs migrated between southern Alaska to the north of the Arctic. So it would have been a similar situation as that of a migratory herd of dinosaurs traveling between say Winnipeg to Arkansas during the year and back again. Very much feasible. When NOVA said that the migration would have been about twice the distance from New York to California, well, they were exaggerating too much. When scientists want to push their own favorite scenario, they often exaggerate on the position they dislike and exaggerate on the position they do like-- such as dinosaurs as permanent year round residents of the arctic. So did the botanist follow up and see what kind of plants lived in the southern tip of Alaska? And was it a temperature akin to what is in Arkansas of a mild winter with plenty of forage still abundant? Also, I was wondering where the poles were some 70 to 60 million years ago and likely not in the same arrangement as today. And there may have been alot of geothermal up near the arctic during the Cretaceous for there was alot of vulcanism going on during that time. And I wonder what would happen if a volcano surfaced in the Antarctica in future years, whether a vulcano can melt alot of the Antarctic? Iceland is a good example. Archimedes Plutonium www.iw.net/~a_plutonium whole entire Universe is just one big atom where dots of the electron-dot-cloud are galaxies. |
