And while "it is too early to say anything about the people building this roundel," it's clear that they were part of the Stroked Pottery culture(opens in new tab), which flourished between 4900 B.C. and 4400 B.C., Jaroslav Řídký, a spokesperson for the Institute of Archaeology of the Czech Academy of Sciences (IAP) and an expert on the Czech Republic's roundels, told Live Science in an email.
4900 - 4400 BC carbon dated = when? It's a case for New Tables.
- 2153 B. Chr.
- 0.706677 pmC/100, so dated as 5003 B. Chr.
- 2131 B. Chr.
- 0.718838 pmC/100, so dated as 4881 B. Chr.
- 2086 B. Chr.
- 0.743062 pmC/100, so dated as 4536 B. Chr.
- 2064 B. Chr.
- 0.754934 pmC/100, so dated as 4364 B. Chr.
So, it started between 2153 and 2131 BC and went on to between 2086 and 2064 BC./HGL
(5003 + 4881)/2 = 4942 (carbon date 42 years off)
RépondreSupprimer(2153 + 2131)/2 = 2142 BC for real
(70.6677 + 71.8838)/2 = 71.27575 => 2800 extra years
2800 + 2142 = 4942
(4536 + 4364)/2 = 4450 (carbon date 50 years off)
RépondreSupprimer(2086 + 2064)/2 = 2075 BC
(74.3062 + 75.4934)/2 = 74.8998 => 2400 extra years
2400 + 2075 = 4475 - no
(4536 + 4536 + 4364 + 4364 + 4364)/5 = 4433 - no
(4536 + 4364 + 4364)/3 = 4421 - no
(4536 + 4364 + 4364 + 4364)/4 = 4407 (carbon date 7 years off)
(2086 + 2064 + 2064 + 2064)/4 = 2070 BC
(74.3062 + 75.4934 + 75.4934 + 75.4934)/4 = 75.1966 => 2350 extra years
2350 + 2070 = 4420
Stroked Pottery flourished between after 2142 BC and 2070 BC.
For seventy two years or less.
