) is the name of a hunter-gatherer and fisher, pottery-making culture dating to the end of the Mesolithic period.
Like the Ertebølle culture, they lived near open water, in this case creeks, riverdunes and bogs along post-glacial banks of the Overijsselse Vecht.
Recent excavations show a local continuity going back to (at least) 5600 BC, when burial practices resembled the contemporary gravefields in Denmark and South Sweden "in all details", suggesting only part of a diverse ancestral "Ertebølle"-like heritage was locally continued into the later (Middle Neolithic) Swifterbant tradition (4200 – 3400 BC).
The artifacts are in an excellent state of preservation, having been protected by anaerobic mud.
On the disadvantage side, water movements have disrupted many sites.
The Ertebølle population derived its living from a variety of means, but chiefly from the sea.
