German paleontologist Ernst Frieherr Stromer von Reichenbach first sighted them in 1911, identified four new species, collected fossils, and deposited them in a Munich museum where they were destroyed by bombing during World War II. US graduate student Josh Smith (now paleontology, Washington U. ) led a team back to Egypt in 2000 to continue the work. Science writer tells the story in a companion to a television documentary.
