... of the upper Wood Bay Formation argue against a source area in the west. The shales of the Plantekløfta Member contain numerous groups of in situ trunks of Archeosigillaria of up to 40 cm length, which are mostly tilted to the west. This indicates transport directions from the east of the Billefjorden...
