Editorial Reviews

How is it that dinosaurs managed to survive and even thrive in the gloom of the dark and frigid polar regions? It is one of paleontology's most intriguing enigmas; but now, a unique field expedition covered exclusively by NOVA will set out for Alaska's North Slope to defrost a jackpot of new fossil clues.With the help of stunning CGI, experts will breathe life into the polar dinosaurs' lives and environment in vivid detail. The team of researchers will combine extreme engineering and perilous fossil hunting-digging a tunnel into the permafrost in order to collect the dinosaur bones-and with Alaska's spectacular wilderness as a backdrop, Arctic Dinosaurs will reveal a prehistoric lost world for the first time.Special DVD features include: materials and activities for educators; a link to the NOVA Web site; scene selections; closed captions; and described video for the visually impaired. On one DVD5 disc. Region coding: Region 1. Audio: Dolby stereo. Screen format: 16:9 Anamorphic.

Arctic Dinosaurs: Warm-Blooded Creatures of the Cretaceous is an episode of the award-winning public television series NOVA, now available on DVD. A field expedition sets out Alaska's North Slope to search for the answer to a quandary: how did dinosaurs survive in the dark and frigid polar regions? Researchers dig a tunnel into the permafrost in order to collect dinosaur bones, an activity that carries its own perils, while other experts decipher the evidence in order to bring their hypotheses to life with CGI animation. Special features include printable materials for educators and described video for the visually impaired. An amazing fresh look at these remarkable ancient reptiles, perfect for school and public library DVD collections as well as for the enjoyment of dinosaur lovers everywhere. 56 minutes, closed captioned.

5.0 out of 5 stars opens up some intriguing questions June 21, 2010
By Haseeb
Nova documentaries have always been first rate. I don't think I've ever seen a Nova documentary I didn't like. This documenatary on Arctic dinosaurs is no exception. This documentary takes us above the arctic circle to examine curious fosils scientists have found there. We see reconstructions and animations of the fosils and discussions on the finds. How did they live? What did they eat? How did they survive the polar winters? These are some of the many intriguing questions asked. There are several plausible sounding answers, but no one knows for sure whether they are correct. The most intriguing suggestion is that the current theory as to how the dinosaurs became extinct has been precluded. If the arctic dinosaurs could survive polar winters, then surely they would have been able to survive an asteroid or meteor crashing into earth and the resulting debris blocking out the sun for a while. So how did the dinosaurs become extinct?

4.0 out of 5 stars Under the pole star August 7, 2013
"Arctic Dinosaurs" is a fascinating NOVA-PBS documentary about fossil finds of dinosaurs in northern Alaska, a region relatively close to the North Pole. Indeed, it was even closer during the so-called Age of the Reptiles. How could dinosaurs, large and supposedly cold-blooded, thrive under such conditions?

Painstaking research seems to suggest that the Alaskan climate during the Cretaceous wasn't Arctic, but temperate. It resembled that of the Alaskan panhandle. However, this still means that the winters were cold and forbidding. Add to this the "Arctic night". For various reasons, palaeontologists believe that the surprising diversity of dinosaur species found in the North Slope didn't migrate further south, but stayed put.

This opens up a lot of intriguing questions about dinosaur biology. Were they really cold-blooded, like crocodiles or lizards? Or were they actually warm-blooded? Birds, after all, are warm-blooded - and they descend from dinosaurs. Personally, I've always been fond of the idea that dinos were warm-blooded, furry and multi-coloured, so the idea of giraffe-like hadrosaurs living under the northern lights has an intrinsic appeal, LOL. (NOVA doesn't discuss their colour, though.)

"Arctic Dinosaurs" ends with the obvious follow-up question: if dinosaurs were warm-blooded (or something close to it), why didn't they survive the climate change after the asteroid impact at the end of the Cretaceous? The scientists interviewed on the show suggest that the climate had began to change for the worse already before the asteroid impact. Climate change was the favoured explanation for dinosaur extinction about 30 years ago, so it's interesting to see that theory stage a little come back. In a dramatic finish, the narrator suggests that perhaps the Alaskan dinosaurs might have been the last of their kind...

Definitively worth watching if you are interested in dinosaurs, or Alaska.
