James A. Jensen

Who was James A. Jensen?

James Alvin Jensen, was an American paleontologist. His extensive collecting program at Brigham Young University in the Utah-Colorado region which spanned 23 years was comparable in terms of the number of specimens collected to that of Barnum Brown during the early 20th century. He was given the name "Dinosaur Jim" during the media coverage of his activities. Perhaps his most significant contribution to paleontology was to replace the 19th-century web of external metal struts, straps and posts that had been used to mount dinosaurs with a system of supports which were placed inside of bones, which produced free-standing skeletons with few or no obvious supports.

He is credited with naming and describing Supersaurus and Torvosaurus.
