       The Zechstein (Permian) basin and the later (Jurassic) Kimmeridgian 
basin in the North Sea were known to be connected to a boreal province of 
"bugs" (loose sense) decades ago. The necessary work was done for petroleum 
basin understanding.
       Pertinent to the WIS, I've seen discussion of the provinciality in the 
Kimmeridgian North Sea region bugs in relation to models of oxygenation of 
the Kimmeridge Sea and the stirring consequent from currents. It was 
considered an important point for explaining/ understanding variations in the 
total organic carbon content of the Kimmeridgian, which is the main source 
rock in this play. What I can't remember is if this was "in the literature" 
or in oil company confidential documentation. I think the context was 
geosteering using palaeoenvironmental palynology. About 5 years ago.
       Anyway, the presence of Triassic marine beds in East Greenland should 
come as no surprise in this context, and my memory tells me that it's old 
news.
