 The project that has been carried out for a couple of last years that's connected with the lithic analysis and researches as well as the resumption of archaeological survey and excavations with the goal to investigate the first inhabitants in Latvia has called for a need to revise and update our existing knowledge about archaeological finds that could be attributed to the first inhabitants of present-day territory of Latvia. Projectile points as one of the most distinctive tools in the lithic collections can be used as important diagnostic factor to determine presence of certain archaeological industry or culture and region. Therefore the goal of this presentation is to show the lithic projectile points from present-day territory of Latvia that could be dated and now I'm saying could be dated to younger Trius and Preboreal period. So that correlates with late Paleolithic and early Mesolithic 11th, 9000 million BC. From this period in Latvia at the moment we know 25 sites. However only 14 were found in 14 signs were found projectile points and here I need to say that till 70s, middle of 70s we didn't know about Paleolithic at all in territory of Latvia and for the couple of last years the count of sites has raised rapidly mainly because not of discovery of new sites but rediscovery of finds that already were excavated and collected during excavations in till 70s, 60s and even earlier of 20th century. So yes you can see the site distribution and it's mainly the all sites are mainly distributed in two basins of the two major rivers it's Dalgaver river and Lialupa. The first site of time we'll talk about is the most recognizable late Paleolithic site in Latvia, no doubt that's Salzburg-Slaug school. First Flint stray finds there were collected during the rescue excavation in a light iron age settlement at Burial yard from 1967 till 1972 and during next two seasons in 1973 and four stone age excavation team led by Olga Zagorska joined these iron age excavations and discovered and investigated six complete and one disturbed Flint find concentration. At the moment site is unavailable as it's under the water and nevertheless in Salzburg-Slaug school together were found 47 projectile points. Here you can see the first Salzburg-Slaug school concentration in the first concentration there were found seven points all of them with a tongue. Together at this concentration there were 377 finds from them at 1960s. So the second concentration consisted three as well with a tongue projectile points with the tongues and in this concentration totally were found almost 200 finds. The third concentration consisted six projectile points with a tongue pronounced tongue except this one. It has less pronounced but otherwise according to the way how it has been produced it's very similar to these ones with the tongues. So completely here were found six points here you can see five only because one is missing and nobody knows where it is actually. Sometimes stuff happens in the museums. So the fourth concentration consisted seven projectile points as you can see and again all of them are with the tongues very pronounced basically produced in the same way from the same type of blades. The biggest concentration of projectile points were found in the fifth Flint concentration place were totally were collected more than 400 finds from them a bit more than 100 were tools. The sixth concentration of Flint there were found eight projectile points again all of them with the pronounced tongue and five more points were discovered as straight finds but if you look at closer to the excavation plan you can see that there is an area where most probably were disturbed one more concentration and the point that's left side comes from that and this one which actually don't have tongue and most probably it looks like a lancet type or we call it willow leaf shape type point it has been discovered as straight find and wasn't connected to any of concentrations. So majority of points that was discovered in Salisbury's Law School are highly standardised they are relatively the same size and latest technological research of site materials done by Inger Berchansen has proved that these finds are connected with the Swedarian technological tradition. As finds were collected in a sand layer there was no organic preservation so actually this site hasn't been dated with IMS dating and it seems that it won't be because at the moment we can't get there. So fragment of tangs I have had and several other Flint tools were collected in Spietini plotter site during the excavations in early Middle Iron Age Burial Mount and settlement site in 1971 and 73. Site by itself was known already from the end of 19th century and first excavation there were carried out already in 80, 88. All Flint finds were found in Iron Age layers sand layers under the Burial Mount and you can see that as well Arrowhead with very pronounced tang. So one more tanged point have been found on banks of river Lialupe in Mezhuotnes Hillfort. Hillfort is situated on the left bank of river on a 15-metre high cape therefore it has steep slopes on the side of the river. Arrowhead was found in between the layers of late Iron Age 12th century in 1939 during the excavations carried out by Waldemar Dinterz. It's typically tanged Arrowhead. Its tip is broken and it was produced from 1.6 cm wide blade. That's very close to those blade wide as most of the Salisbury Slough School Arrowhead has. This Arrowhead is the only find in this site that could be attributed to this early period. The largest collection of lands at Orvillo leave shape to a point that could be attributed to the late Paleolithic and early Mesolithic consist of nine points and it's from Awatni site. Site by itself was discovered in 1991 and in 1993 the first excavations there were carried out by Joga Zagorska. However, all nine points were found in excavations in 2018 and 2019 together with almost 300 flint finds. As you can see, each point morphologically it's different. However, almost all of them except one, this one there, have flat retouch based on the ventral side. All other Willow shape leave shaped points have been found on the banks of Dawga very well. So yeah, two with broken tips, two points with broken tips were found together with around 40 other flint finds that could be attributed to the end of Younger Dryas and beginning of Priborio. They're found during the rescue excavations in Saeopil's Hillfort and Settlement site. Both of them have same small side retouch on a half part and flat retouch on the ventral side. As well at the moment the place partly where these two finds were gathered it's under the water partly and the part which is visible nowadays as an island is completely excavated. Similar but a little bit longer point together with 11 other finds including plates from two opposite platform cores were found around 40 kilometers downstream in excavation of Iron Age Burial Yard at the end of 20s and beginning of 30s of 20th century. All finds were collected in a disturbed sand layer between the burials. Around six kilometers downstream from Salisbury's Low School site was located Renucon's Bronze Age Settlement and Burial Ground. Settlement site, it's easy to say settlement site but actually that was a hillfort. Site in 1966 and 1967 were excavated by Janis Groudens and together with two and a half thousand bone, stone and bronze artifacts were found 68 flint finds as well. One of them is this bone, sorry, flint point. Two more flint points that could be attributed to the final Paleolithic were discovered one of them was not very far from Salisbury's Low School but as you see morphologically it's different as well one more in a hillfort as straight find in between the layers of late Iron Age again. So and in the early Mesolithic this sweet defined complex in present day of Latvia were replaced with the new complex the Kunda culture we call it and from that period we have like five places where there were found projected points were found the only one which has actually dates is the Sveiniyaki lower layer that this flint point it's dated in a layer, were found in a layer that has been dated the end of 10th and the beginning of 9th millennium BC. All other two, these two others were collected as straight finds in 19th century and nowadays they are in Tartu, Tartu, yeah. There are two more, these we can't call this pulley type arrowheads were collected during excavations in Lake Burtneck region and two more were discovered in a Dalgaver river basin as total straight finds one of them are Jessica Hillfort together with this arrowhead in the same layer there were couple of very distinctive and very nice looking Mesolithic finds as well and one more most beautiful one I would suppose this one were found in all in a bog at the moment we don't know exact place but yeah that's for the future so to sum up everything in total at the moment we have like 50 lake Pallelitic tank points from 3 sites 13 wheel of leaf shape points from 4 sites 2 points from 2 sites that are very tricky and 7 early Mesolithic pulley type points from 5 sites and all points are produced from non-local quality clotaceous flint in South Splice Law School there are two of them that has been produced from chocolate flint actually and the thing is that my problem is chronology because as Thomas said already we don't have exact dating from the sites and up till now it was believed that Kunda culture developed after or from the Swaderians however the latest research in Lithuania done by Gabriela Gudartaita Gudartiene shows that these actually this transformation and late Swaderian tradition disappearance or extinction from the central northern part of Lithuania could happen much later and the main change might have happened in the not final Pallelitic and early Mesolithic transition but later from early Mesolithic to middle it's around 7900 and 7800 so and as I told already most sites actually could be described as trade finds from places that has been completely excavated and at the moment are unavailable or destroyed so yeah those are the main problems that we have so thank you for your attention
