"Ancient Turkic oz tamga (rune) on medieval buildings commissioned/built by ancient Turks (Turkish -> Turkic, according to Turkic Academy of OTS, Turks originate from Scythia, Western Eurasia, not from the Far East or Siberia). Ancient Turkic Tamga Alphabet (tamga, lit. meaning “rune”): 𐰋𐰭𐰏𐰇:𐱅𐰭𐰼𐰃𐰘𐰭:𐰚𐰇𐰲𐰦𐰼:𐰭𐰼𐰃:𐱅𐰇𐰼𐰜:𐱅𐰇𐰼𐰀:𐱃𐰆𐰺𐰣:𐰇𐰓:𐱅𐰭𐰼𐰃:𐰖𐰽𐰺

In both Islamic and pre-Islamic Shamanist (Tengrist) era, usage of many tamgas including Oz Tamga was recorded in many balbals and kurgans around both west and east Eurasian Steppe. Seljuk, Timurid and other Turkic empires' buildings in Western Eurasia, Turkistan (“Central Asia”), Persia, Azerbaijan, Anatolia and the Balkans also had many Oz Tamgas inscribed on. Many Seljuk buildings in Anatolia, some Ottoman buildings in the Balkans also have Oz Tamga inscribed on them.

Since the Mongols rose up as late as 1200s, in other words, since they were heavily influenced by their Turkic overlords both religiously and socio-culturally for around a millenium until 1200s, they also probably got their Genghisid Oz Tamga from Ancient Uyghurs (see: Uyghur Khaganate [744-840], the successor of Eastern Turkic Khaganate; other Uyghur kingdoms last until 1200s) who they were heavily dependant on in terms of statecraft.

Linguistically, the English equivalent of oz tamga (oz rune) in Turkic antiquity could be “fylfot” which is first recorded in English language as late as c. 1500s.
