Perspectives: Paleontology. Polar Dinosaurs

In 1960, footprints from Spitzbergen showed that nonavian dinosaurs had once lived at polar latitudes. Initially, this intriguing find remained an essentially isolated discovery, but during the past 20 years, much information about polar dinosaurs has been unearthed. The late development of knowledge in this field was largely a matter of logistics: The fossil remains of most polar dinosaurs are to be found today at high latitudes and often in remote areas. Their discovery and collection are, therefore, more costly than is generally the case for comparable lower latitude fossils.
