base notes	Base of Tournaisian Stage. Age used Devonian spline for base-Sulcata (and base-Tournaisian); not the 359.69 of Carboniferous-Permian spline. Radiometric ages in lowermost Carb and uppermost Dev constrain this boundary age to be closer to 358.9; but GTS2020 (Agterberg-Gradstein) did not incorporate the dates on the 'opposite period' for their Spline versions for some reason; but ran the Carb one separately, then used that Carb base-age for top Devonian. Zone Patrognathus crassus of Davydov'04 is equivalent to Siphonodella sulcata of other schemes.				comp notes
