• coordinate estimated from map

• outcrop-level geographic resolution

When: Lituigraptus convolutus graptolite zone, Leangen Member (Solvik Formation), Aeronian (440.8 - 438.5 Ma)

• "The lower range...is near the lower limits of the transition zone, and the rest of it is probably deposited entirely within the transition zone...The bioclasitc beds and fine sst interbeds interpreted as storm events...very high frequ. of storm events indicates shallow conditions...upper range of BA 4 into 3...degree of transport minimal."
• "The type sequence consists of mudstone interbedded with very abundant, thin coquinas and fine sandstones."
