a close connection between the prominent temperature rise at the beginning of the Interstadial and the expansion of the hunter-gatherers into the northern Lowlands. The existence of a primary “pioneer phase” in the re-colonisation is contradicted by proof of e.g. an early Central European Magdalenian in Poland. Today it is commonly accepted that the Hamburgian, featured by "Shouldered Point" lithics, is a techno-complex closely related to the Creswellian and rooted in the Magdalenian. Within the Hamburgian techno-complex, a younger dating is found for the Havelte phase, sometimes interpreted as a northwestern phenomenon, perhaps oriented towards the former coastline. The Hamburgian culture existed during the warm Bølling period, the brief Dryas II glaciation (lasting 300 years) and in the early warmer Allerød period. However, the distribution of the Hamburgian east of the Oder River has been confirmed and Hamburgian culture can also be distinguished in Lithuania. Finds in Jutland indicates the expansion of early Hamburgian hunters and gatherers reached further north than previously expected. The Hamburgian sites with shouldered point lithics reach as far north as the Pomeranian ice margin. The younger Havelte phase has been proven for the area beyond the Pomeranian ice margin and on the Danish Isles after c. 12,300 BCE. The "Backed Point" lithics of Federmesser culture are usually dated in the Allerød Interstadial. Early Federmesser finds follows shortly or are contemporary to Havelte. The culture lasted approximately 1200 years from 11,900 to 10,700 BCE., and is located in Northern Germany and Poland to south Lithuania. Fish-hooks were discovered in Allerød layers and emphasize the importance of fishing in the Late Palaeolithic. A certain survival of late Upper Palaeolithic traditions similar to contemporary Azilian (France, Spain) becomes apparent, such as the amber elk from Weitsche that can be considered as a link to the Mesolithic, amber animal sculptures. Bromme culture sites are found in the entire southern and southeastern Baltic, and are dated to the second half of Allerød and the early cold Dryas III period. The "classical" Brommian complex is typified by simple and fast, but uneconomical, flint processing using unipolar (single-platform) cores. A new development noticed in Lithuania introduced both massive and smaller "tanged Points". In Bromme culture this technology is proposed to be an innovation derived from tanged Havelte groups. As such, derivation of Bromme culture and even migration of its representatives from the territories of Denmark and northern Germany have been proposed, although
