An ancient dried-up lake at Petrified Forest National Park offers some answers. It’s full of coprolites fossilized feces. Inside the droppings are tiny bones leftover from somebody’s lunch. Scientists can take high-resolution scans of these minuscule fossils to see what they look like from all sides, even if they’re embedded in rock. Then, they blow up the image and print an oversized copy on a 3D printer.
The technique allows them to study never-before-seen details about the Triassic’s smaller residents. It’s changing what we know about the animals that evolved into today’s frogs, lizards, and salamanders. Scientists can trace the pathways of the nervous system or study the shape of tiny teeth to learn about what these animals ate and how they looked and behaved. And they can share fossils with scientists on other continents at the click of a button. The 3D files are available online, so teachers can print them in classrooms. Students can pick up bones that, in re
