Re: Allometric equations for predicting body mass in dinosaurs
I have a question about this paper: Allometric equations for predicting body
mass of dinosaurs. Journal of Zoology, June 21, 2009 DOI:
10.1111/j.1469-7998.2009.00594.x.
I do not have the paper, but was wondering if an estimate of 18 tonnes for
Brachiosaurus is reasonable (estimate reported here:
http://www.livescience.com/animals/090621-dinosaur-size.html)? That seems way
too light for a 70 ft long animal.
The reason I bring this up was because I was trying to come up with a better
estimate of the weight of Puertasaurus (here:
http://ztwarmstrong.deviantart.com/). In the end, I get an estimate of 58
tonnes for Puertasaurus using Argentinosaurus as a model, and using the
drastically reduced weight estimates of the above paper. Any thoughts would be
appreciated.
Do these equations affect how those, like Greg Paul, get there weight estimates?
BTW, if anyone has a pdf of the paper I would be much obliged to receive a
copy...
Thanks,
Zach
P.S.: How many cervicals and dorsals do titanosaurs have respectively? How
would you estimate the length of the cervical series and the dorsal series (and
caudal series) respectively?
