This is 100% factual.
I've been telling people that for years!
So do they spring away to escape predators? Fantastic idea!
Arboreal titanosaurs? We need bigger trees! Yggdrasil might be large enough....And bigger claws. Massive claws with titanic musculature and huge bone anchor points. And legs designed to wrap around the trunk, and hold the body close to the tree. And, like tree climbing spikes, any tree they climb will likely be so damaged by the holes in the bark that it dies shortly after being used as a makeshift ladder. Although I suppose if the feet were very large in surface area and more along the lines of a gecko's feet, there might be enough van der waals forces to hold up the several dozen metric tons of titanosaur without turning the tree into kindling....The bonus here is that those gecko feet would work on cliff faces, as well as trees, although I am thinking that those feet would be a very large proportion of the body's total mass. Really big feet, teeny tiny body (relatively)!
Huge trees. And sap-eating birds that follow them as they climb.
A highly interesting idea, plus makes sense, now I wonder how big it is.
Such convergent evolution there :3.
