Mammoth for Dinner, by Susan Kepecs
(with a Knight 1909 portrait of the main
course):
(Radiocarbon years do not equal calendar years
because the amount of radiocarbon in the atmosphere through time has not been
constant; it varies as much as 15 percent, making radiocarbon time older or
younger than calendar time. In the case of Clovis, a radiocarbon age range
of 11,000 to 11,600 years is actually about 13,000 to 13,500 calendar
years. All dates in this article are in radiocarbon years.)
And I wonder if the same ratio of difference
(11,300/13,250) applies to all dates used. Clarifies my mind.
Anyway, when we get substance-based dates for
dinos, can I assume they are calendar years, or should I do an equivalent to my
meters-to-feet conversion calculation?
Gee.
