Significance
High
Low diversity marine invertebrates (bivalves, nautiloids, brachiopods), palaeoniscoid fish, sharks, fish coprolites, protozoans (foraminiferans, radiolarians), petrified wood, palynomorphs (spores, acritarchs), non-marine trace fossils (especially arthropods, fish, also various “worm” burrows), possible stromatolites, oolites
Additional Comments
Transition from marine to brackish salinities early in history of epicontinental Ecca Sea.
Marine body fossils rare (e.g. Douglas area)
Biogenic origin of “stromatolites” within carbonate rocks needs confirmation.
