Though not nearly as common as the bone fragments and bits of tooth found at dinosaur fossil sites, remnants and impressions of dinosaur skin are not as rare as you might think

The proposal of pack-hunting dinosaurs is old news in paleontological circles, and the hard evidence to support the claims about Tarbosaurus has not yet been released

Richard Polsky writes in the introduction to his travelogue memoir Boneheads, it was time "to experience life all over again," and a search for the most famous predator of all time seemed like just the thing

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...

What was Kelmayisaurus? Discovered in 1973, the lower jaw and partial upper jaw of this large, predatory dinosaur from the Early Cretaceous of China have been frustratingly difficult to interpret. Maybe Kelmayisaurus belonged to some obscure lineage of archaic theropod dinosaurs, or perhaps the fos...

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 ...

Non-avian dinosaurs have been extinct for about 65 million years, but that has not stopped them from showing up on Twitter. Several dinosaurs have been making the most of the social media platform. The Smithsonian National Museum of Natural History doesn't have one yet—I would personally love to he...

Everybody knows that Tyrannosaurus had small arms tipped in only two fingers. The relatively small arms of the Late Cretaceous predator are part of its charm. When paleontologist Henry Fairfield Osborn described Tyrannosaurus in 1905, however, the fingers and forearm of the dinosaur were missing. E...

A Gorgosaurus tries to scare a group of Troodon away from a hapless ankylosaur in this promotional image for March of the Dinosaurs.
The Discovery Channel's "March of the Dinosaurs" is the kind of dinosaur documentary that could not have been made until this point in time. When I was fi...

Sauropods were humongous creatures, but how they got so large is a mystery that paleontologists are still trying to unravel

TMP 2003.45.64 is not exactly a headline-making fossil. The left lower jaw of an Albertosaurus, most of the teeth have fallen out and the bone is only one part of a well-known species represented by many other skeletons. But, for those who know what they are looking for, this specimen bears the tr...

If you spot a tiny tyrannosaur peeking out from the back of a jeep in the vicinity of Fort Campbell on the Kentucky-Tennessee border, you aren't seeing things. The dinosaur and the custom-painted Jurassic Park jeep are the creations of Daniel Peterson, the director of the U.S. Army Museum at the mi...

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...
