Late Weichselian flora and vegetation of Andøya, Northern Norway‐macrofossil (seed and fruit) evidence from Nedre Æråsvatn
A Late Weichselian sediment column from Nedre Æråsvatn, Andøya, Northern Norway, spanning c. 20000 to 11000 B.P., has been analysed with respect to phanerogam macrofossils. Seeds are rare in the lower, marine part of the sequence (19500 to 15500 B.P.). They occur more frequently in the post‐15500 B....
