Hi,
I need to calculate a bodymass for a fossil mammal from it's lower molar row lenght (LMRL). The equation is straightforward enough but it seems that I must be misunderstanding something as I'm getting the wrong result.
Values:
BM = bodymass (in grams)
LMRL = 106.1 mm
Slope = 3.03
Intercept = -0.39
The equation is thus:
Log BM = 3,03*log(LMRL) -0.39
I'm getting the answer 321,093 since this should come out in grams that would mean 32 kg which I know is much too small a number for this mammal. What am I understanding wrong? I'm guessing it has something to do with "Log BM" and that it requires some extra step to acquire the actual bodysize?
I would be very thankful for any help!
