Some recent items:


Sauropod teeth, juvenile stegosaur Âteeth found at Teete in Yakutia in Siberia. The region was already above the Arctic Circle during the Early Cretaceous, so this would be the most northern evidence of sauropods known. The fossil teeth of many kinds of animals suggest a high latitude refuge for relict populations of more primitive groups that had gone extinct or been replaced in other regions. (in Russian)
