October 15 is National Fossil Day, and there’s no better place to celebrate it than in the massive quarry house in Dinosaur National Monument, located on the state line between northwest Colorado and Utah.
The famous, 150-foot-long quarry wall is embedded with more than 1,500 fossilized dinosaur bones. It’s literally a log jam from an ancient river where dinosaurs drank and hunted…and died.
The quarry is preserved to show the bones located exactly as they were found, and high-tech touch screens allow you to zoom in for a close-up view of a particular bit of skeleton.
Having recently been on a Dino Dig, I can’t imagine how many years it would take for paleontologists to excavate this many fossils. (And work still goes on nearby; a team recently discovered an ichthyosaur, a giant marine reptile.)
As my brother, David, and I entered the quarry hall, there was dino-magic in the air. A little girl let go of her father’s hand and skipped over to the fossil wall. “I’m so excited! I can’t believe these are real dinosaurs,” she said, petting a tibia bone in the okay-to-touch zone.
To help us make sense of the jumbled hodgepodge of bones, which belong to at least seven species of Jurassic-era dinosaurs, David and I used a guide booklet, “What Kind of a Bone Is That?” (It cost us just $1 at the Visitor’s Center.) The two of us reverted to full dino-nerd mode: we spent a couple of hours ID-ing interesting bones, like the sacrum and back plate of Stegosaurus. At the end, we just sit on a bench and speechlessly gaze at the magnificent, intact skull of Camarasaurus, a gigantic plant-eater.
Park rangers are always stationed in the quarry hall to answer visitor questions. We talked to ranger Tiffany Small, who pointed out a few more details that we’d missed. She also impressed upon us how unique this view of the past we were witnessing really was. “People come into the hall and cry because they’re so moved that this quarry has been preserved—and that the remains of these prehistoric animals are still here for us to remember.”
When I asked Ranger Small who gets most excited when they come into this hallowed hall of ancient bones, she replied: “Dinosaurs bring out the kid in all of us.”
I guess she could tell David and I were reliving our dino-crazy childhood.
