Metacarpal (cast) of the gigantic sauropod dinosaur Supersaurus vivianae from Jones Fossil Farm, Worthington, MN. Below, sculptures (not in my collection) by paleontologist James A. (“Dinosaur Jim”) Jensen of various Morrison Formation dinosaurs, including (center) Supersaurus. This photo first appeared in my book The New Dinosaur Dictionary.
