they really do this animal justice, they are able to bring across the point that this animal was big... really really big.

Imagine how a human heart would weigh to a Syrian hamster. A hamster teaching about it's owner. It's heart would be immense. Weighing as much as 3 adults weighing 120 grams which is 360 grams it would pump a huge amount of blood. It has to beat every second and ous beats 5 times when a human heart beats once. It has 2 gient chambers, large valves and huge pipes. A human hand and wrist alone would weigh nealy as much as 4 grown hamsters which is pretty heavy. A human foot alone would weigh as much as 6 syrian hamsters. A titanosaurous dinosaur heart would weigh as much as 3 grown human beings. A human heart would weigh as much as 3 Syrian hamsters.

I had to Google this. An etruscan shrew heart beats around 835bpm but has been recorded at 1511bpm. That's 25 times.. a second. That must sound like a hum.

It's almost as breathtaking as the dinosaurs themselves... One of my oldest friends believes the earth is flat. And she said that she believed that the Smithsonian threw out bones of giants. For some reason, I was able to dissuade her from the latter theory, but not the one about our planet being a pie plate or whatever the hell they think it is. I've a hunch she's gone full MAGA.

It would have crumbled under its own massive weight they are impossible under today's gravity

@dankygrade2270 6 лет назад

sean sullivan the atmosphere was different before the meteor hit that's what alowed them to grow so large

@TITANSofTheEARTH 5 лет назад

WHAT? *they are impossible under today's gravity* ?! lol - the gravity was the same... there was only more oxygen...

@matwatson7947 5 лет назад

Gravity doesn't change. The atmosphere was different if thats what you mean but that doesn't massivly limit a species growth

@cameronhodgetts920 3 года назад

What, so you're denying the fact that it can be proven to exist because it's existence doesnt fit with what we know/believe to be possible? Dude, our understanding changes. If evidence comes along that creatures of this size existed, then clearly what we understand is wrong

If anyone from this thread still cares, the air sacks and hollow bones of birds is an ancestral trait amoung the dinosaurs, sauropods had thes air sacks and lighter bones which made them lighter than one would expect as well as increases their breathing efficiency
