Program Description
Most people imagine dinosaurs lurking in warm locales with swamps and jungles, dining on vegetation and each other. But "Arctic Dinosaurs" reveals that many species also thrived in the harsh environments of the north and south polar regions. NOVA follows two high-stakes expeditions and the paleontologists who push the limits of science to unearth 70 million-year-old fossils buried in the vast Alaskan tundra.

70 million years ago, Alaska was where California is right now....
I tinks de description is off. If you go to Ellesmere Island, you can walk the beaches in July and pick coral, the same coral that you find in Hawaii today. In order for it to grow, you need an ambient temp of roughly 80 degrees.....which would suggest to me that its not always been cold there!
Birds, and reptillians, are the progeny supposedly. The dinosaurs were reptilian with air temperature bodies, slow metabolisms, and temperature regulated growth cycles. The avian with rapid heartbeats, high internal body temperatures, high metabolism, and therefore much higher caloric intake... Wait...what?
“70 million years ago, Alaska was where California is right now....”
Hi:
Actually part of Alaska was still in the arctic at that time. If you watch the program you’ll see that they show that the dinosaurs were living there during the winter. I thought I would post about it because that kind of blew me away. Thought others might be interested in it.
...also, you could go to Coral Harbor, on Southampton Island, walk the beaches and find fossilized coral...thus the name Coral Harbor, Nunavit, Canada. General location is way up in the north western part of the Hudson Bay...
just saying... there was warm water all around there for a significant period....somewhat equatorial...
Hi SC, this may interest you and your pingees.
“The dinosaurs were reptilian with air temperature bodies, slow metabolisms...”
Actually the scientific consensus and evidence seem to show that many dinosaurs were fast and warm blooded as were the birds that evolved from them.
The program alert thread would be a neat idea until it got flooded with everyone’s particular interests. I can just see the alerts now:
Rerun of the “Who Shot JR” episode of Dallas on TV Land
Paula Dean cooking Bacon Wrapped Cupcakes on the Food Network
“Day in the Life of a Domesticated Skunk” on Animal Planet
Hi:
Thanks for pinging him. I don’t know how to do that myself.
Also, from reading threads on here I know that you are into the cometary impact hypothesis dated 12,900 years ago. In fact Nova did a program on that called “Megabeasts’ Sudden Death”. It aired March 31, 2009. I don’t know if you saw it. I’m sure they will re-air it like this show, which was originally aired on October 7, 2008.
The reptilians came from where?
That’s because there were no “harsh polar Regions” back then.
Not to mention a totally different respiratory system.
Hi:
Thanks for replying. Maybe we could have one each for different areas of interest. That way it wouldn’t get to off topic. Just a thought.
Good thing about a 70 million year old dinosaur bone is that after you’re done with it you can throw it in your gas tank.

Yes, but it wasn’t quite equatorial. There was still winter and snow, apparently.
