Nearly six years later, I’m visiting the fossil prep lab at the Royal Tyrrell Museum in the windswept badlands of Alberta. The cavernous warehouse swells with the hum of ventilation and the buzz of technicians scraping rock from bone with needle-tipped tools resembling miniature jackhammers. But my focus rests on a 2,500-pound mass of stone in the corner.
At first glance the reassembled gray blocks look like a nine-foot-long sculpture of a dinosaur. A bony mosaic of armor coats its neck and back, and gray circles outline individual scales. Its neck gracefully curves to the left, as if reaching toward some tasty plant. But this is no lifelike sculpture. It’s an actual dinosaur, petrified from the snout to the hips.
