Is there any other interesting fossils that would be known to be from the Arctic Ocean? It is the last region not already in my

Triassic Trace Fossils In The Arctic - Svalbard
ERK posted a topic in Fossil IDHi everyone ! Just discovered this forum and thought I should give it a go regarding identifying some trace fossils.

So, feel free to comment. - Picture 1 shows a vertical 'tube' burrow in a heterolithic setting (mud + sand). The preliminary interpretation is that it was deposited in the offshore-transition zone.
