A dapper brontosaurus
“Brontosaurus” (invalid genus since the 1900s, now Apatosaurus) didn’t have separate toes. I’m not exactly sure how to describe them, so I drew a bit of a fix over your original image.
Also note the tail should taper much faster, ending in a thin whip, which was a diplodocid’s second line of defense against predators. Another thing is that the proportions are all wrong for it to be an Apatosaurus, as the neck’s much too long, the tail’s too short, and the front limbs are too long (reference this skeletal).
Also note that the columnar limbs and lack of proper fingers would not allow Brontosaurus to put on clothes, hold a watch etc.
