2. Patterson, airstrip - subfossil shells

Subfossil shells can be found inside the red frame.The old Patterson-airstrip was built on top of consolidated marine sediments. In the sediment are numerous subfossil marine molluscs. Most common species is blunt gaper (Mya truncata) and is often in live position. In a few samples the soft tissue of the animal is fossilized which is rare. The age of the subfossil shells are 20.000-22.000 years and the lived shortly before the Late Glacial Maximum at about 18.000 years age. The sea level at that time was about 5-10 m above present level.
