According to the Smithsonian, dinosaurs were very popular back in 1985. Heck, "Jurassic Park" didn't come out until 1993 — and they were still cool. Anyway, astronaut Loren Acton took bits of bone and eggshell from the duck-billed dinosaur Maiasaura Peeblesorum. The fossils were found at a nesting site. Dinosaurs didn’t return to space until 1998.
