Firstly, I'd like to thank all those who helped me out with my questions on
Bruhathkayosaurus, especially Mike and Mickey.
Secondly, yes, this article is concerning sizes too (this is actually the
thing I find most intersesting about dinosaurs). I'm working on a book on
the largest sauropods, and I'm going REALLY crazy when it comes to sizes.
I'm not only talking about the ones where evidence is sparse. Take
Brachiosaurus. We have a complete skeleton, and as Mike noted in one of his
replies, estimates range from 15-180 tonnes. That's a difference of more
than 1000%. Seriously, considering B. brancia is probably the best
represented sauropod, that's more than ridicoulous (no offense).
That's why everything I've read in books, articles, and on various websites,
has really got to me. For example, Gillete's book cited Seismosaurus at a
minimum of 120-150 feet long, and 100 tons. Other books put it at over 170
feet and 150 tons. A couple of the newer articles cite it at 110 feet and 25
tons. See what I mean? How is it possible for all those writers and
scientests to make such precise estimates when evidence is so minimal. A
very good book called 'Supergiants: The Largest Dinosaurs', give estimates
from the scientests themselves, which I've discovered are more or less
If you want a real idea of what I mean, I'lle give you a few more examples
about how the sizes range from various sources:
1. Argentinosaurus: 72-150 feet, 73-110 tons
2. Paralititan: 65-130 feet, 60-80 tons
3. Seismosaurus: 100-180 feet, 25-150 tons
4. Supersaurus: 80-150 feet, 30-100 tons
5. Amphicoelias: 125-205 feet,98 (this was Mike's estimate, probably the one
I trust the most)-170
6...... Aw forget it!
That probably gives you the idea of what I mean. How is it possible for
anyone to cite estimates like these with such terrible evidence. Could
someone help me out here? Otherwise, I'll leave my book on hold until more
evidence is discovered, or I'll use my own calculations (which are just as
unreliable, as I used better known genera like Diplodocus and Brachiosaurus
for comparisons, and the estimates vary just as crazily for them, too).
