Tegiszhol: radiocarbon determinations from Russian-language steppe archaeology

1,425 radiocarbon determinations extracted from 46 Russian-, Kazakh- and Ukrainian-language archaeology publications covering the Eurasian steppe and forest-steppe. Roughly 90% do not appear in any public international compilation. 179 determinations (12.6%) were transcribed blind from page images by 15 paid annotators; on radiocarbon age and error there is no confirmed transcription error, placing the error rate for those fields below 1.7% at 95% confidence. Version 1.0 is PROVISIONAL: coordinates cover only 11% of records, the site field is not verified to the same standard, and novelty is an upper bound; see README.md for the full limitations.
