New Analysis Shows Dinosaurs Not As Heavy As Previously Believed.

Cognitive Dissident writes "Discovery.com has an article on a new study using computer modeling to estimate the actual amount of flesh needed to cover the skeletons of dinosaurs. Based on a comparison with modern animals, it indicates that these animals could have weighed dramatically less than has been previously estimated. 'A huge Brachiosaur, once thought to weigh 176,370 pounds, is now believed to have weighed 50,706 pounds.' That's only about two-and-a-half times the weight of a modern African elephant. If other evidence can be reconciled with this, many estimates of the ecosystems dinosaurs lived in will also have to be revised."

Dinosaurs. Not heavy, just big boned.

pounds? for a minute there I thought we were talking sience...

Let's make the African elephant unit a standard.

overblown as usual

This is just like all other science. The most sensation, impressive sound stats that's backed by "real sounding" science wins. Impossibly heavy lizard vs reasonably, logically sized lizards. Let's go with the freaking lizo-tank. Mathematical error or magical substance we can't see or measure = entire 1 hour specials on dark matter. One of millions of things we have flying around up there vs careless aliens visiting...well that's alien UFOs of course. I think that might even have its own channel actually. This really needs to stop.

Re:Dear discovery channel,

Low accuracy and high precision. Now this is a scientific article that has some credibility.

The brachiosaur you write about...

[BlueTak]

Was it a european or an african brachiosaur ? Do you think it could carry coconuts ?

Finally scientific evidence comes out saying it is all because of their genetics. We should be ashamed of all the years we've been calling dinosaurs old and fat.

Wouldn't the buoyancy reduce their weight even more? Really, is there any reason they can't?

And I presume they'd outgas the excess hydrogen as burps which their gizzards (full of flint and iron ore) would ignite?

Sorry Kapiti, that should have read:
"A huge Brachiosaur, once thought to weigh 12597.9 stone, is now believed to have weighed 3621.9 stone."

Come on mate, how do you think American's translate to kilograms, and vice versa?

Badly, if their use of apostrophes is anything to go by.

"This happens all the time in the popular press. Clearly you can't estimate the weight of a creature you've never seen to within 1 lb"

I went to the museum and saw a big Tyrannosaurus skeleton and I asked the guide how old it was.
He said: "75,000,013 years."
I said: "Wow! Since when do they know the age up to the year?"
He said: "Well, it was 75,000,000 years old when I got this job and that was 13 years ago."

The only US contributions I recognize, are those with the spelling errors.

The comma you used does not belong there. Could you please let us know where you're from? I need to know which nationality introduces superfluous commas.
