Tashkovon kulttuuri näyttää olevan hankalampi ajoittaa kuin Krotovo, koska useat artikkelit viittaavat vain yhteen radiohiiliajoitusten sarjaan, joka sisältää keskenään ristiriitaisia tuloksia. Näiden tulosten perusteella Tashkovon kulttuuri olisi syntynyt myöhemmin kuin Krotovo, ehkä kolmannen vuosituhannen eaa. viimeisellä neljänneksellä.
"Monuments of the Tashkov culture of the Bronze Age have been studied in the forest and forest-steppe zones of the Tobol basin, for which even the relative chronology remains largely debatable. Isolated stratigraphic observations point to the pre-Srubna-Alakul period, although some authors are of the opinion that synchronization is possible (Stefanov, Korochkova, 2000. Pp. 81–87). Radiocarbon argumentation is of little use in this dispute so far. Of the nine dates (Kovaleva, 2005. P. 106), two belong to the 4th millennium BC and cannot be used. The rest also do not demonstrate homogeneity and, when summing up the probabilities, give a fairly wide interval – 2290–1880 (2900–1600) BC. In this form, the dates allows us to state the general synchronicity with the Seima-Turbino phenomenon and the Sintashta-Abashevo period." [1]
"The chronological position of the Tashkov complexes, despite the availability of fundamental studies, remains one of the most debated problems. [...] The calibrated age of the Tashkovo culture monuments, based on a series of radiocarbon dates, places them in the range of 2050±200 years BC (Kovaleva, 2005, p. 105)." [2]
"One of the authors of the article attributes Tashkov to the Early Bronze Age, suggesting that this culture preceded the Seima-Turbino (ST), Sintashta, and Krotovo complexes, and generally developed within the pre-Seimin chronological horizon (Kovaleva, 1997). The other two authors, on the contrary, believe that Tashkov metalworking was carried out in the early phase of the Eurasian metallurgical province (22nd/21st–18th/17th centuries BC) (Kuzminykh, Degtyareva, 2012, pp. 224, 238)." [3]
"[S]ome authors attribute the Tashkov antiquities to the Early Bronze Age, while others, for various reasons, assume their synchronicity with the Seima-Turbino, Sintashta, and Petrovsk monuments (Degtyareva et al., 2014, p. 23). Radiocarbon argumentation comes down to less than ten dates with a huge range of values. Their summation merely confirms the presence of two intervals that have no points of contact: with a probability of 68.2% — 4000–3600 (13.8%) and 2300–1700 (54.4%) BC; with a probability of 95.4% — 4400–3300 (23.8%) and 3100–1600 (71.6%) BC. The trail of early values is formed by two of the seven intervals with a very large standard deviation (430 and 150 years), the calibrated interval of which falls on the 5th–4th millennia BC, i.e. coincides with the earliest Eneolithic values. It is unlikely that these figures can be accepted; it remains to turn to the rest, the summation of which gives: 2290–1880/2900–1600 BC (Fig. 5), which is, of course, too broad for strict judgments, but corresponds well to the general chronology of the Urals and Western Siberia (Molodin et al., 2014, Fig. 2)."
