Two recent archaeological investigations in Germany have yielded interesting information about the changes in society from the later fifth century onwards that led to the emergence of the early medieval post-Roman culture that succeeded it.
The first was at Delbrück Bentfeld near Paderborn in Westphalia and which yielded what appears to include the site of a cremation of a man who may well have served as a Roman mercenary with accoutrements from the Imperial army. The funds are outlined and discussed in an LBV article which can be seen at The Tomb of a Germanic Mercenary Who Served in the Roman Legions and an Unusual Well with Glass and Organic Remains, Found in Germany
The second site is at Bad Füssing, near Passau on the border of modern Germany and Austria in the Inn valley.
The discoveries are again related to funeral practices in a site which appears to have been used for a considerable length of time.

These two excavations, from distant and different regions, do suggest cultural fluidity and interchange along and across the borderlands of the Empire and Germania in these centuries.
