Two of the samples seem very East-Med, not very surprising off course. One sample plots exactly as the EIA MJ-12 (UKR_Cimmerian_o) and LIA Scy197 (Scythian_MDA) & co. So seems there was a long term continuity in that area. the last one actually plots like some of the intermediate Moldavian Scyth samples:

There is an incredible amount of variation in the proportions assigned to the "Steppe_Proto_Yamnaya" component or the "Yamnaya_RUS_Samara" component.

[AimSmall]

This one adds rafc's two identified close samples.

   
Note: MJ12 has 16% coverage and SCY197 has 20.85%

The first run is against 10K years ago.  Yamnaya are about 5K or 6K years younger.   Just how Tomenable did his calculator.

Thanks, this nicely illustrates how close SRR26291264 is to those two samples who lived nearby, but one probably about 500-700 years earlier and the other 1100-1300 earlier. He clearly is very likely a local.

Different look using Tomenable's 6th Century BCE dataset.

That reminds on the comment from the Bulgarian forum, which predicts Southern Bulgaria becoming Anatolian shifted since the Hellenistic period. Clearly, the coastal region of the Western Black Sea would trend towards the same, since it was as Greek colony:

Histria or Istros (Ancient Greek: Ἰστρίη, Thracian river god, Danube), was founded as a Greek colony or polis (πόλις, city) near the mouth of the Danube (known as Ister in Ancient Greek) on the western coast of the Black Sea. It is near the modern town of Istria. It was the first urban settlement on today's Romanian territory when founded by Milesian settlers in the 7th century BC. It was under Roman rule from the 1st to 3rd centuries AD.

Some of those present could be Dacians or Scytho-Sarmatians though, partially at least. No known haplogroups yet?

¿ what its greek anatolian or roman imperal ?

[alexfritz]

ROM_11D is the only paper sample with a radiocarbon-date
dating to 433-566 CE ie the late late-antiquity though still abit pre Justinian; while ROM_9C gets an arch. date per grave goods to the 3rd-4th c. which could still fall into the early late-antiquity ~Diocletian-Constantine

overall a familiar sight in yet another prov and i think we are now getting a pretty good idea of how important Hellenistic Anatolia was for the Rom/Byz period and its profile, eg all we see in Italy is a massive influx of Anatolians and a dissolved IA cluster shifted to Anatolians (ie the real overlap) for all samples 0-200 CE (incl Pompeii f1R) and in Naissus the sample R6769 dates to 26-126 calCE, not to mention the entire data from Viminatium (cf paper); keeping in mind that the Danube was a major expansion and the most important frontier

despite Histria leaning to the late-antiquity the sample SRR26291260 is still very reminiscent of the 'shifted to' cluster in Roman Italy, judging by the ph2ter maps (#266) and closest ancient inds on Vahaduo; not knowing which sample ID fits which G25 ID its still pos that the sample is from an earlier time since the arch. timeframe of the overall site seems to be the 2nd-6th c.

¿ what its greek anatolian or roman imperal ?

Greek-Anatolian aka Hellenistic-Anatolian would be samples labeled TUR_Anc from the 'Southern-Arc' paper (Lazaridis 2022) and Roman Imperial (cf Viminatium paper) got a definition from the Reich-lab as a cluster of all C5 samples (xR45), all C6 samples (xR111) and the C4 samples R76 R75 R73 R41 R38 R126 from the Antonio/Moots paper

atleast for the latter alot more samples post-Antonio/Moots can be added from Italy and the Balkans eg

SRR26291264 : ROM_10D

Thanks. I guess to identify the others we need the published paper, the pre-print only mentioned four out of the 10 samples they finally used. If someone can access the published paper and put the table with samples here, that would be welcome.

Edit: here is a presentation:

He says they only succeeded with 4 samples. I assume they re-ran the other samples afterwards. The csv-files only list 8. So maybe the files are for a completely new paper ...

[corrigendum]

Two of the samples seem very East-Med, not very surprising off course. One sample plots exactly as the EIA MJ-12 (UKR_Cimmerian_o) and LIA Scy197 (Scythian_MDA) & co. So seems there was a long term continuity in that area. the last one actually plots like some of the intermediate Moldavian Scyth samples:

SCY197 might be from a later era because he couldn't be dated. 

In any case, SRR26291264 is closer  to west Balkan samples than to Scy197 or MJ-12, hence I don't think that it represents a local profile (although I don't consider scy197 to represent a local profile as well, but a west-central Balkan one):

SRR26291260 represents local Thracian and Greco-Anatolian ancestry.

SRR26291262 is an individual of East Med origin.

SRR26291258 originates from one of the steppe-derived groups which got there from Ukraine.



Overall, a very diverse site - as would be expected in any urban center of the Roman era. 4/4 samples represent different trajectories of ancestry.
