In 1913, paleontologists at the American Museum of Natural History made plans for what would have been a spectacular reconstruction of a prehistoric battle. Too bad that their plans did not come to fruition.Tyrannosaurus rex—the most celebrated dinosaur of all time—made its debut at the AMNH. The f...

Everybody knows that Stegosaurus had four tail spikes. The formidable weapons this odd dinosaur sported were some of its most prominent features. Yet, when Stegosaurus was new to science, it seemed as if this dinosaur bristled with even more spikes. In 1891, the first full skeletal drawing of Stegosaurus ungulatus was created under the direction [...]

Dinosaurs are ambassadors of paleontology. Much to the frustration of scientists who study plants, invertebrates, and even fossil mammals, the word "paleontologist" is closely associated with the image of scruffy researchers digging around for dinosaur bones. Despite the popularity of dinosaurs, th...

I thought that I had seen just about every major dinosaur documentary from the 1980s, but I just found out that I missed at least one: the Smithsonian Video Collection's Dinosaurs. It was one of many programs—like A&E's miniseries Dinosaur!—that were inspired by deep changes to what we thought ...

I spent Sunday morning among the dinosaurs of Smithsonian's National Museum of Natural History. The skeletons of the prehistoric creatures stood nearly shoulder to shoulder—the Tyrannosaurus appeared to snarl at a nearby Triceratops, and an Allosaurus stood dangerously close to the business-end of...

When the American Museum of Natural History's paleontologist William Diller Matthew published his book Dinosaurs in 1915, no one understood how the famous Mesozoic creatures originated or went extinct. Both the beginning and end of the "Age of Dinosaurs" were mysterious. Yet, tucked away in a foot...

Despite decades of progress for women in science (and some arguments that no more is needed), the playing field still isn't level. But do all the advantages men get result in them thinking more highly of their expertise than female scientists do? Three researchers, including D. Carolina Useche at t...

In 1925, John Scopes, a high school biology teacher, was put on trial in Tennessee for having the audacity to teach evolution to his students. In the 21st century, teachers don't have to worry about being arrested for teaching this fundamental topic in science, and the Supreme Court declared teachi...
