It could step over an elephant: https://paleontology.us/wp-content/uploads/2020/02/David-Att... from: https://paleontology.us/titanosaurus/

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?

giraffes have super long necks and yet they bend over to eat. The answer is runaway sexual selection (or at least that's the answer wrt to giraffes).

Giraffes also reach up to eat.

(They do look quite funny when bending down to drink, though!)

I used to live in Tanzania and over there, the trees are mostly shorter than the giraffes, but I'm sure they reach up to eat sometimes. I guess my point was that giraffes didn't evolve long necks to eat.

This centuries-old question is still not settled, right?

It’s only just occurred to me that dinosaur bones like this are in soil not rock? Even if it’s not technically soil, the bones are at least buried in something fairly soft.

That’s crazy. I’ve only ever thought of fossils as being encased inside hard rock.

The bias of the fossil record makes a discovery like this so unlikely that it’s objectively joyous when it happens.
