 Okay, thank you. So for a couple of years now we are having a research project at the Klaipeda University which which is the main purpose of it is to identify and study the early Holotene sites which is now submerged in the Baltic sea waters and on the coast as well. So as you will see later, we have some issues in that area of research, but if you are interested in some case of this research of these studies, you can just type in in the research case search function this name and you will find some updates and information about this project and I try to keep it updated every time if we have something new. Okay, so the research area is as you can see is a coastal part of Lithuania and it's a problematic part because in the inland part especially in the southern and southeastern part and in the western area further back to the from the coast, we have lots of stone age sites mazolitic burials, mazolitic settlements and other stuff that is is very rich in flamed bone antlers and so on. Yeah, but the coast is not so rich in mazolitic sites. So today I want you to present three main sites which is here marked by black dots which represents lithics, bones and antlers. One site represents only lithics. It's the newly excavated one and other two sites are from older collections and they represent only osseous material. Okay, so but first of all I would like to make some glimpse into the underwater stuff that we have and we have some submerged forest areas in different sea areas. You can see RF2, RF3 in those parts. We have mainly pine trees, submerged pine trees that we already detected. As you can see some examples are here. Mainly it's a big trunks and locks and we sampled them. We have even found some files driven into the seabed which is dated as you can see in the mid of 8th millennium BC and we have like well these dates are older now and they are not from AMS dating labs so I just made a compilation of our old dates from the trees, submerged trees and as you can see lots of them goes to the pre-boreal times and last year with the collaboration between German, Lithuanian, Latvian and Belarusian archaeologists we made a presentation at last year's EAA about the dating of T-axes and we have this one T-axe from one of the submerged places in the Baltic seawaters and we have now this is an old T-axe that is dated in Lithuania and I think we have not at least now we have no more T-axes but this T-axe which is in red square is one of the earliest in the whole Lithuania. Which is from the submerged area. Okay so the first site that I want you to represent is Oktumalamo which is in the southern part of the coastal Lithuania. It was discovered the stone age sites there was discovered in 2004 and it was excavated but it was like rescue excavations you know and the material material was never delivered to the museum and we had no any information about it until 2013 so when we had that information we already knew that this site is the most earliest one in the whole eastern Baltic coast. So this is the current view of the island now island that contains three sites you can see one two and three as you can see this area is in the peat extraction fields and it's we are very likely that it's not destroyed and we have a good opportunity to study it and we made excavations in last year in 2018 in summer and now this year we made excavations in 2019 so I will try to represent the the newest stuff that we have now but research is still ongoing and some other ideas will come up later I think so yeah so this is the main tools from those sites this this lithics are from whole three sites it's combined and as you can see in the left corner this is a excavation material from excavations in 2004 and according to that material the site was the sites actually was identified as the possible Arends-Burgen site I'm not sure why but the number one if you can notice in the bottom left is a fragment of a tank point so according to this the previous previous studies said that it's probably Arends-Burgen but nope this is actually a Svidarian fragment yeah so and in 2018 we managed to find more flints because you know this area is non-flinty area so it's these sites contains not much flint but we managed to find something and we even managed to find two points one as you can see here is almost a complete full point of the Svidarian technology and the next one is only a tank fragment but we already know that it's a Svidarian as well so yeah that's the main tool kit from the 2018 and this is from the 2019 what we have here and the excavations just confirmed that we are dealing with Svidarians because as you can see the number two we have a small Svidarian point and maybe the number one it could be the Svidarian point as well but we are not sure yet so the flint if we combine 2019 and 2018 stuff consists about 150 flints only but we have lots of blades you know very quite legural blades and we have actually only one flint core this is number 13 it's an opposite platform core but it's very interesting that some blades are very typical to the pulley technology which but to the technology that later pulley probably used because we found very regular blades there especially and maybe some prototypes we have here as well and what is the most interesting thing according to the geological part of those of that island of those sites the island was the sea level sorry no sea level but lake level was high enough that the water just overcame the island and according to the data from 19th century even the whole hill in that place was overgrown by peat on the surface and only just in the deeper layers there was a sand so probably in my opinion it could be the case of course we have to make some more research but it could be the case but we are dealing with the short and excluded the Svidarian site it's not a mixed site in my opinion yet yeah so according to the archaeological data we also have lots of non-flint rocks and a big part of its debitage like coarse granite cores and hammer stones and net sinkers blades and especially flakes and if we look closer into the statistical point of view so you can see that only by several by four percent flint material overcomes the non-flint material so we are actually we are making now the chemical analysis of flint in that from those sites and we will compare it with the outcrops analysis in the of Namuna's basin with the cretaceous flint from Lithuania and Belarus and we'll see if probably yeah it could be that the flint came from there but who knows yeah and if you look into the non-flint material and rocks we see that granite dominates the whole assemblages and the next site is a smelter site it this assemblage of bones and antlers was found in 1974 and delivered to the museum it was excavated in the peat area that is now destroyed by the constructions of shipyards and as you can see we have lots of tools which consists of axes also pressure plakers and so on and even some amber the detailed study of those this assemblage was published in 2015 by Gittis Pilotshavskis in Estonian Journal of Archaeology you can find in there however I want to to take part into some two only two tools from this assemblage which is axes and I wanted to show you and to talk about its decorations yeah the first one as you can see is an anthrax or hoe I'm not sure the big part is considered as a broke and it has a special way of decoration you know like removing their movement the cortex and that way the decoration was given I know the exact similarities from Straubi Egede in Denmark I saw some in the Copenhagen in National Museum so it's very interesting that we have some analogies here in Lithuania and the next one is as you can see the anthrax as well but this is a bad example of the museum stuff we have a like lines decoration the regular lines decoration by the base part of the anthra and if you look into the microscopical view of the decoration itself we see some interesting stuff in technological point of view what's of course the whole technology consisted of cutting by a flint knife by flint boring because we detected lots of rocks traces there sharp rocks traces there and of course the last stage was the polishing into softer rock like sandstone or maybe other one but what's the interesting point is that as you can see the top left photo it in one part it has like a oblong bit in impressions so I'm not sure if it's from maybe from anthra natural or or not so it's very interesting and who knows what's what it's not like what's sorry what tool was used for decorating it we have no idea yet and if it's the decoration at all we are not sure so and the other one it's just like a simple lines which was made not by one cutting but several times cuts and it was polished as well later after the tool was completed and the last site that I want to show you today which has a sandwich of antlers and bones is a palanga site which has also one of those data t-axis the site was also published in 2015 by Gitis Lichowskas and it has also some elements of decoration on on tools and especially the conical bone point which has cross and net patterns of decoration here so we have lots of you know those conical points bone points in Lithuania but if you look closer into the dating of the site yeah we see that the site dates like in the middle and at the end of 5th millennium CalBC sorry I haven't showed you probably but this site is earlier by the dates of those two tools and of course we made a more sampling of tools especially decorated tools and we sent them to the lab but we are still waiting for the results to come yeah so my point is that if we trust those dates this is the first example of that decoration on that tool type in Lithuania later we have the continuity of this tool type and decoration in eastern Lithuania and we have like a continuity especially in the late Neolithic at the end of free millennium CalBC yeah and if you look closer into the decoration part we see that for the decorating of that tool like three or two tools at least was used because we see that is difference in lines in the width of lines so it makes sense that probably the upper part was decorated by a different tool and the lower part was decorated by a much smaller tool and now to conclude first of all I would like to express that as you can see we have great lack of data from late Paleolithic and Mesolithic in coastal part of Lithuania but we have much potential for underwater studies there and I think that lots of treasures are submerged now and we just have to make a research and the earliest example of hunter-gatherer site in that area is that Oxtomala more that is now considered as the Sviderian sites yeah and in my opinion it has no mixed material here from other periods from later Mesolithic or Neolithic even and we see that the flint was introduced probably into that area from southern Lithuania but we are not sure we are making some research later and we see that in the Mesolithic collections that we have the main tools was made of antler and bones and less flint because we have actually no flint of Mesolithic no Michael is and have a typical Mesolithic tool kids in the coastal part of Lithuania so and currently we have earliest Mesolithic decorations there in Lithuania in the coastal part of Lithuania so thank you very much
