It is quite interesting though that Osborn was so far ahead of his time in believing brachiosaurus could tripod up on its hind legs and tail. But itwas common knowledge even back then, that some species of living monitor lizards do exactly the same thing.

Ironically most people nowadays, even dinosaur buffs are so familiar with the “horizontal stance” of theropod dinosaurs, that they are quick to call any depiction of these dinosaurs in the old “upright stance” to be unauthentic. But this is silly, for theropods probably “tripoded” quite a bit, in order to get a better view of the countryside, just as some monitor lizards do today.
