Archeologists from Lund University in Sweden have map out a endocarp age web site from 9,000 years ago . This one , however , is place underwater in Hanö Bay in the Baltic Sea .

The squad has discovered some unbelievable artifacts since it was first discovered 7 twelvemonth ago . They found eight fishing traps made of braided hazel pole , an   denotation of extended sportfishing that   suggests that the area had inhabitants for at least part of the year . There ’s also a well - preserved pickaxe made out of elk antler with an dedication whose meaning has unfortunately been recede in clock time .

allot to the research published inQuaternary International , the surface area used to be a lagune and the investigator were capable to reconstruct what it looked like during the Mesolithic .

” If you desire to to the full understand how humans dispersed from Africa , and their way of life , we also have to find all their settlements . Quite a few of these are presently subaqueous , since the sea level is higher today than during the last glaciation . human have always preferred coastal web site , ” say graduate student and chair author Anton Hansson in astatement .

” As geologists , we want to recreate this area and understand how it looked . Was it warm or cold ? How did the surroundings change over metre ? ”

consort to the estimation , the realm would have feel mild temperatures at least during the summertime , guaranteeing a good life history for the Mesolithic inhabitants of the region . The rise of sea levels happened after the site was buried in deposit , which helped the site and its determination to be preserved until today .

The mapped site are site about 3 kilometers ( 1.9 mile ) from the current shoreline and about 20 meters ( 65 feet ) below sea stratum . They dug up to 3 metre ( 9 infantry ) into the sea bottom and performed several tests to found what the actual underwater topography of the region is like .

” These site have been love , but only through scatter find . We now have the engineering for more detailed interpretations of the landscape , ” contribute Hansson .

This is the oldest coastal construction found in Northern Europe and it is potential that it ’s not the only one .
