• Pollen analysis: Detailed profiles were established on a regional and a more geographical extensive scale, demonstrating the delay of certains regions to the ice-core results.
  
  For example the transition to deciduous forest occurred earlier in the south-east part of Southern Scandinavia and Northern Germany compared to the north-west.
  
  " The start of rapid Holocene warming at 11,7 k.a.(c. 11,6k.a.cal BP) initiated a complex series of climatic responses in northern Europe with associated responses in biological systems and their ecology.
  
  The late Glacial succession of vegetational immigration has been well described in northern Europe over many years. These studies were mostly based on pollen analyses and much of the biostratigraphic zonation was determined from southern Scandinavian sites.
  
  They also detected hitherto undocumented rapid climatic changes during the early Holocene (c. 11,653 cal BP. These events, recorded in correlated relative chronologies, have since been shown in many paleoclimatic indicators from the northern hemisphere within absolute chronologies.
  
  The events, which are often suggested to be associated with meltwater pulses into the North Atlantic Ocean, were part of an early Holocene dynamic climate with rapidly changing temperatures and precipitation regimes, possibly impacting the developing landscapes and the large scale migrations of the associated flora and fauna. Disentangling this complex mixture of responses to early Holocene climatic change with all their associated time delays can be aided by sites with secure stratigraphic contexts and the integration of different scientific disciplines (Jessen et al. 2015).



• Lithic analysis: Microliths and lithic blade technology are the most important issues for a relative chronology. Microliths and their frequencies, suggested a division into six phases (Petersen 1973). More recently, a study of the Maglemose culture lithic blade technologies defined seven different concepts (Sørensen 2006)



• Modern C-14 AMS dating, especially AMS technology, pretreatment protocols and Bayesian modeling revolutionized absolute dating during the last years with a high precession.
