Thermopolis, Wyo. – A small town in north-central Wyoming known for the mineral hot springs that give it its fancy Greek name also is a rich dinosaur graveyard. It is located on the long, wide strip east of the Rocky Mountains nicknamed the “dinosaur highway” because so many of the awesome beasts lived and died there.
Dinosaurs lived 65 million to 228 million years ago. During that time, seas rose and retreated, mountain ranges grew and eroded, the climate warmed and cooled, volcanoes erupted, and tectonic plates shifted.
An enormous north-south waterway called the Western Interior Sea once covered what are now the Western plains. The wetlands and lowlands flanking it were prime dinosaur habitat.
Today, this is semi-arid countryside with crenellated layers of rock from various geologic periods lying at or near the surface. In this often surrealistic landscape, dinosaur fossils are not uncommon.
A road trip to the fabled national parks of the West can be interwoven with stops along the dinosaur trail, where families can see dino-rich museums and dig sites – and perhaps even be paleontologists for a day.
Thermopolis, which was founded in 1897 and has the no-frills, homespun look of many small, Western towns stands out from the rest in having a nearly life-sized metal sculpture of a dinosaur at the main intersection (and location of the town’s only traffic light). Along with the Wax, Teddy Bear and Hot Springs County museums, the town features the Wyoming Dinosaur Center, which has first-rate exhibits and a high-tech paleontology lab.
Among the awe-inspiring treasures are an allosaurus, a triceratops and a camarasaurus found on the Warm Springs Ranch, where the first of the center’s hometown collection of bones was unearthed in 1993 and where paleontologists are still digging.
New species are still being found and assembled. Each one is a thrill – akin to the discovery of a new planet. One still-nameless species displayed at the Wyoming Dinosaur Center is a long-extinct armored creature about the size and shape of a giant tortoise. The center also is working on “super-saurus,” a Jurassic giant among giants that is estimated to have been 135 feet long from snout to tail, stood 27 feet at the shoulder and weighed 50 tons. By contrast, a record blue whale (the whales are the largest animals living today) measured 108 feet in length.
Weather permitting, the center offers hourly tours to a hillside on the outskirts of Thermopolis where scientists and volunteers are at work digging for bones. For a more expanded experience, adults and youngsters can work alongside the pros in a Dig-for-a-Day program.
“There are uncountable fossils to find,” says the center’s science director, Scott Hartman, “but a finite number of people digging for them.”
Unspoken is the hope that the beautiful red Triassic layer, green-gray Morrison formation or other rocks in Wyoming and elsewhere will yield another as-yet unknown species.
Even a one-day dig provides a hands-on sense of what it takes to discover dinosaurs. Participants learn to differentiate bone from stone, are introduced to the tools of the paleontologist’s trade and are sent, under close supervision, to a dig site to unearth what they can.
Each little bone fragment, confirmed by a paleontologist, is a small triumph, but alas, the bones must remain there – hopefully to be assembled with other bones. It is always possible to buy a fossil, often from China, in the gift shop.
Digging is a painstaking task. Experienced paleontologists work with chisels, trowels and other large utensils. Amateurs, especially children armed mostly with enthusiasm, are provided with, as Hartman puts it, small implements “that can’t do much damage.”
Finding truly complete fossil remains of a single dinosaur at a single site is the stuff of which paleontological dreams are made. Bones were almost always separated, broken, scattered by a flowing river or raging storm, carried off by scavengers, consumed by bacteria or in other ways scattered.
Also, smaller, softer bones and cartilage tended to deteriorate or disappear before they could be fossilized.
After fossils have been disinterred and location documented, small fragments are gathered and large ones jacketed in protective plaster and moved to a lab, where they are meticulously cleaned.
Technicians use tools as delicate as dental picks. Then, perfect casts are made of ribs, pelvises, skulls, spine and other bones.
To assemble a complete skeleton, they often have to combine castings and real bones from different animals of the same species. Lightweight, real-looking castings of heavy fossilized bones of huge dinosaurs eliminate the need to stabilize specimens with huge, unaesthetic metal supports. Some institutions indicate which portions of displayed skeletons are real and which are reproductions. But whatever the proportion of original to cast, it is impossible not to be awed by creatures that roamed the planet so long ago.
From small museums to large institutions, dinosaurs still rule along the dinosaur highway. Dinosaur National Monument, straddling the Colorado-Utah line and under National Park Service jurisdiction, showcases species and a quarry where many specimens were found, including an extremely rare infant stegosaurus.
In addition to numerous dedicated dinosaur centers and small museums in the region, a couple of major museums also boast world-class fossil exhibits. The Museum of the Rockies on the University of Montana campus in Bozeman houses the largest collection of dinosaur fossils from the United States. Now open is the first phase of a new dinosaur complex designed by world-renowned paleontologist Dr. Jack Horner, an adviser to the “Jurassic Park” films.
The Denver Museum of Nature & Science’s notable “Prehistoric Journey” exhibit displays its spectacular dinosaurs in the context of their habitat and also has arranged them in a timeline that begins with the most primitive life-forms, microbes from 3.5 billion years ago.
Paleontologists have equal admiration for fine examples of older, simpler fossils, from ferns to trilobites, but youngsters seem to have eyes only for dinosaurs.
