At the San Diego Natural History Museum, a visitor might find paleontologist Ashley Poust firing up a tiny jackhammer. He uses to chip away rock surrounding a fossil.
"Even though it looks scary vibrating at that speed, it wouldn’t hurt you unless you really stuck yourself with it," Poust said.
Poust is familiar with digging up, cleaning and analyzing fossils. So, when he looked at a fossil found by a farmer in China over a decade ago, he could tell it had the remains of a new species of dinosaur.
