How Dinosaurs Thrived in the Snow

https://www.smithsonianmag.com/science-nature/how-dinosaurs-thrived-snow-180976435/?utm_source=smithsoniansciandnat&utm_medium=email&utm_campaign=202012-science&spMailingID=44065800&spUserID=NzQwNDU1OTA4MzQS1&spJobID=1900806682&spReportId=MTkwMDgwNjY4MgS2

Quote: 'But some polar dinosaurs truly thrived. The raptor-relative Troodon was a feathery, eight-foot-long dinosaur with large eyes. While rare elsewhere, Fiorillo says, "it is the overwhelmingly abundant theropod dinosaur." The small-carnivore?s large eyes may have given it an advantage, especially during the dark months.'
