How I Spent My Summer Vacation

            One of the best adventures of my life occurred one summer when my family and I spent a week in western Colorado. During two of those days, we joined a dinosaur dig. It was very hot and dirty. Insects swarmed us, the nearest porta-potty was a half mile away – and I never had more fun in my life!

            The paleontologist in charge of the dig, Jim Kirkland, told us where to dig and what to do. The area we dug in was a vast bone bed dating to about 150 million years ago, during the late Jurassic (one of the three time periods during which dinosaurs lived). Many dinosaurs had died, perhaps in a flood, and had their bodies swept into this huge heap. Their bones were all jumbled together. Diggers in that area have found bones from Brachiosaurus, Stegosaurus, Allosaurus, Apatosaurus, and other Jurassic dinosaurs. We would not get to keep any bones we found. They would stay with the paleontologists for study, as they should.

            The rock was crumbly, like flaky pastry, and easily removed with just our hands.  We searched through it and then discarded the rock into plastic bins. It’s not always easy to tell what’s rock and what’s bone, but at this site the rock was a light brown and the bones much darker brown, almost black. We moved a lot of rock before we saw anything. (Caption: That’s my husband, John, in striped shirt, my son, Patrick, in red cap, and Jim Kirkland in cowboy hat.)

            That thrill, though, when you see a bone that’s been buried for 150 million years is not like anything else. It was definitely worth the hours of digging. I felt awed and elated and also a little humble. I’m a tiny speck in this universe. You know, we also spent two days white water rafting while we were in Colorado, but digging up dinosaur bones was more exhilarating!

            During those two days digging I only found three bones, but one of them in particular interested Dr. Kirkland (in red shirt at left; me in blue). It looked like a piece of armor from an armored dinosaur, but at that point no one had ever found an armored dinosaur in Jurassic rock. Further excavation after I left produced more of that dinosaur, and it turned out to be just what Dr. Kirkland suspected: an armored dinosaur, the first ever found from the Jurassic Period. He named it Mymoorapelta and wrote to me about it. He also put out a press release, and I got my picture on the front page of the local newspaper!

            Mymoorapelta is a nodosaur, which means, among other things, that it doesn’t have a club at the end of its tail. It was one of the earliest armored dinosaurs ever to have lived, and, at 9.8 feet long, one of the smallest. It ate mostly plants that grew low to the ground, such as ferns, cycads, and conifers. Its teeth were small and leaf-shaped. Scientists can’t say for sure, but it is likely that it lived in herds.

            I will leave you with this question: If you found a new dinosaur, what would you name it? Please let me know in the comment section.
