Some recent items:


Sauropod teeth, juvenile stegosaur  teeth 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)
