William Thompson provided the link, www.msn.com/en-us/news/us/researchers-lost-world-of-dinosaurs-thrived-in… … I'm not sure if the journalist that did this post was raising a query, with tongue in cheek, or if the author really thought it possible dinosaurs flourished in polar conditions. Whatever, once again we see that consensus doesn't conform with facts.
The Prince Creek formation in Alaska is rich in fossils (of dinosaurs). They have announced a new species – a duck billed dinosaur (was it a bird?). Some 10,000 bones of this species have been found to date. It therefore thrived in a region that is i) cold, and ii) dark for many months of the year. Ugrunaaluk kuukpikensis was 25 feet in length and a plant eater – adding problem number iii) plants growing in northern Alaska. Some 13 species of dinosaur were living the remote part of Alaska – and more will no doubt be discovered in the course of time.
The same story is at http://phys.org/print362130782.html … where we learn that the bone beds is 300 miles NW of Fairbanks and 100 miles south of the Arctic Ocean. It also reveals that a herd of young animals was killed suddenly and buried in order to create the deposit. A touch of catastrophism then.
