Visit your local natural history museum gift shop and you’ll probably find a container of dinosaur toys for sale. Dump out its contents, though, and you’ll likely find some imposters, says Nathan Smith. He should know. He’s director and curator of the Dinosaur Institute in California. It’s part of the Natural History Museum of Los Angeles. Winged pterosaurs are a common fraud. So is the sail-backed carnivore, Dimetrodon. The word “dinosaur” isn’t a catch-all term for just any scaly, prehistoric giant.

Across the river from Washington, D.C., sits Potomac Overlook Regional Park. Hiking paths wind through acres of forest and cultivated land. Peer into the thick woods and you may glimpse a chipmunk or even a deer. And at the visitor center, there are real-life dinosaurs. One of these is Twiggy. Sitting on her caretaker’s arm, her massive brown eyes blink in the afternoon sunlight. Ribbons of brown and white streak her chest. This mimics sunlight hitting speckled tree bark.
This paleontologist solved a nearly 50-year-old dino mystery

Paleontologists have unearthed many iconic dinosaurs, such as Tyrannosaurus rex and Triceratops, from the western United States. Relatively few species, however, have popped up east of the Great Plains. In 2017, ReBecca Hunt-Foster described one of these rarities from the 113-million-year-old remains of a right foot. Describing a fossil requires making a detailed report on how an extinct animal lived. If it’s the first fossil of that species, this is when it gets its official name.

Nicole Xu reached into a Styrofoam tank to grasp a live moon jellyfish. Quickly and carefully, she inserted a tiny electronic device into the animal. “It takes a little bit of practice,” she says. “But once you know how to do it, it’s very simple and very quick.” Xu is an engineer at the University of Colorado Boulder. Free educator resources are available for this article.
