Can someone explain how something like this would work, is blood pressure, gravity affect on body, oxygen absorption.
I really can't get my head around how something like this would be possible, and how it could sustain itself.

Interestingly in the 2nd link that they have this creature towering over the local flora.
The long neck makes more sense if there are trees that size and the neck is to get to the leaves. Otherwise what use is it?

Oxygen-wise, the answer may be a specific one-way lung structure still seen in modern birds.

It's just a render. The other graphic shows it reaching a height of 45 feet off the ground; modern trees far exceed that frequently.

#25> long-necked, plant-eating dinosaur called a titanosaur, potentially the largest ever unearthed. I know the sauropods were mostly vegetarian but I can't help but figure that an animal of that size must have inadvertently swallowed a fair number of smaller animals.
Did scientists ever figure out how sauropods ate enough to support their mass, with their tiny mouths?

Plus isn't accurate that oxygen in air was much higher in the era this new found dinosaur was found?
(edit) seems that this new find would be in the middle of the cretaceous period and according to some quick googling, it is thought the 02 levels were ~30% versus ~20% today.

Yes, up to 35% during the Carboniferous period, which allowed a whole host of creatures to get much bigger than they are today. I'm not sure when it dropped to the modern 21%, though.

Could this also explain why people in the Netherlands got so tall so quickly? Maybe by being below the level of the ocean they get more oxygen?
Edit: there’s no mention about oxygen or seal level in this article about Dutch people’s quick increase in height over the last 150 years https://www.theguardian.com/world/2015/apr/08/scientists-try...

The lowest point in the Netherlands is 22 feet below sea level. There's going to be no meaningful difference between that and zero.

#30My thoughts go the the paelontologist first finding this - they start with a little paint brush, carefully uncovering a tail, then more tail, then a month later they are still on the freaking tail, worn down the bristles on two brushes and thinking "yeah yeah career making discovery but jesus a velociraptor would be done by now."
Edit: This is amazingly cool however - and honestly I cannot wait for Covid to end, decent public funding of science to appear and a facsimile of this skeleton to get stuck in every natural history museum going - my kids will be sick of their dad dragging them off to see a 120 foot long pile of bones - but up close and personal is pretty much the only way to appreciate this sort of thing.
Right that's it - tomorrow it's tape measeures and chalk outlines in the road outside!
