Montana has been working the charismatic megafauna thing for millions of years.

Long before grizzly bears prowled for elk calves along the Rocky Mountain Front, Deinoychus packs chased maiasaurs away from their nests to snack on newly hatched babies. If dozens of Tyrannosaurus rex fossils hadn’t been found in the sedimentary Montana soils, we’d know they were here from all the teeth gashes in the bones of Triceratops they ate.

Finding dinosaur fossils was a regular part of wandering the tumbled foothills along Highway 89, not that anyone much cared. That started changing in 1978 when Marion Brandvold found some particularly tiny bones that turned out to be most the charismatic of all. Her cache of specimens caught the attention of Museum of the Rockies paleontologists Jack Horner and Bob Makela, who concluded they were baby remains of a new species of duck-billed dinosaur.

The significance of Brandvold’s discovery needs some excavation, just like the little fossils. They weren’t simply infantile versions of another thunder-lizard. They opened a window in a time machine that showed dinosaurs had families. They built nests for their babies and nurtured them for extended periods. Egg Mountain avalanched the notion that dinosaurs’ walnut-sized brains weren’t capable of much beyond eating. Horner and Makela named Brandvold’s find Maiasaura Peeblesorum: the Good Mother Reptile.

A life-sized model of a Tyrannosaurus Rex, whose name translates to "King Tyrant Lizard," looms over the Montana prairie between the Trex Agate Shop and the Two Medicine Dinosaur Center in Bynum, both essential stops on the Montana Dinosaur Trail.

Maiasaura also re-juiced the old competitive spirit among dinosaur hunters. Colorado’s Dinosaur National Monument introduced the world to fossil excavation in the mid-1800s. Montana produced the world’s first Tyrannosaurus in 1903. Similar giant skeletons served as circus sideshow attractions as much as scientific investigations around the turn of the 20th century. Big-city museums deployed quick-response teams to claim new dig sites and bring back the latest mystery beast for the clamoring public.

“We were the first county museum in Montana, and the first to display fossils in 1936,” Carter County Museum Director Sabre Moore said of her Ekalaka institution. “Unfortunately, a lot of our fossils leave the state. We’ve been lucky to get some casts gifted back as kind of a thank-you.”

That includes a cast of Wyrex, the Tyrannosaur discovered by local resident Don Wyrick in Fallon County with the unusual distinction of having its tail bitten off by some more aggressive competitor. The original bones are in a Houston lab, but Ekalaka’s showroom will highlight the cast this summer.

For the most part, the early science was limited to getting the bones put together right. Egg Mountain triggered a space-age leap of insight about dinosaur life that could make careers and fortunes. Horner’s lectures on Cretaceous parental habits started filling auditoriums. Fossil-obsessed middle-schoolers soon competed with Hollywood agents for his attention. The result was “Jurassic Park.” Groan if you will, but it spawned four sequels.

It also spawned a few lawsuits, as finders and keepers tussled over who got to possess the best fossils. Brandvold’s eggs and babies wound up split three ways, among the collections at Yale, Princeton and the Museum of the Rockies. The Two Medicine Dinosaur Center in Bynum has its own supply.

“There was a lot of drama involved,” Two Medicine museum director Cory Coverdell said. “Horner discovered the eggs in the rock shop next door. At the time, the only dinosaur on display in Montana was in Ekalaka.”

Fourteen public dinosaur displays now dot a loop more than 2,000 miles long across the central and eastern thirds of the state. They range from the animatronic galleries at Bozeman’s Museum of the Rockies to one of the world’s most complete Tyrannosaurus rex specimens at the Fort Peck Interpretative Center, 385 miles to the northeast. It take nine hours to drive between Bynum and Ekalaka.

Montana’s geography and geology combined to preserve some of the world’s best Cretaceous and Jurassic life evidence. The landscape east of the present-day Rocky Mountains bathed in the edge of the Cretaceous Interior Seaway, whose shoreline shifted from around Choteau to as far east as the North Dakota border.

“It was a time when the global sea level was very high, and we had extreme global warmth,” University of Montana sedimentary geologist Marc Hendrix explained. “There were no polar ice caps to speak of. All that ice that’s today tied up in Greenland and Antarctica was melted.”

The overthrust of the Rocky Mountains caused the older layer of the seabed to flex down to the west, as if the Bob Marshall Wilderness was a diver bending the end of a diving board. Eons of plant and animal species lived and died in that shallow sea, drifting to the bottom in ever-increasing layers. Some deposited in ways that transformed them into today’s pockets of petroleum, natural gas and coal after millions of years. Others did their work much faster, encasing and mineralizing everything from seashells to skin tissue in natural archives.

Leonardo, a Brachylophasaurus considered by the Guinness Book of World Records as the “world’s best-preserved dinosaur,” was unearthed near Malta’s Great Plains Dinosaur Museum and Field Station. That designation could fall after a new discovery published this spring of an ankylosaur with mummified skin tissue along with its bony spikes, horns and hammer-like tail. The creature has such a dominating appearance, the finders named it Zuul crurivastator — for the demon in the first “Ghostbusters” movie and the Latin word for “crusher of shins.”

Locals have been aware of Montana’s superb preservation qualities for longer than the major academic world might acknowledge. Laurie Trexler, Brandvold’s daughter-in-law, recalled working for weeks on a Maiasaur head section where imprints of skin showed the dinosaur had a dewlap, or flap of skin under its jaw. But when the specimen was transferred to an Ivy League university for further examination, the lab staff punched through the skin traces in their haste to “clean” the bone pieces.

Unlike most museum experiences, Montana’s dinosaurs offer a hands-on component comparable to hanging out in Thomas Edison’s lab while he’s inventing the light bulb or Michelangelo’s workshop while he’s carving “David.” Visitors with an afternoon or a week can go out in the field with professional paleontologists and dig up a new dinosaur.

Bynum’s Two Medicine Dinosaur Center, Malta’s Great Plains Dinosaur Museum and Field Station and Jordan’s Garfield County Museum all offer field trips to fossil deposits for actual excavation and recovery. Federal law prohibits private fossil collecting at these sites, but visitors can experience the full spectrum of discovery, recovery and analysis central to paleontology.

“About half our visitors are making a convenient stop between Glacier and Yellowstone (national parks),” Coverdell said in Bynum. “But the other half comes here just for the dinosaurs. Montana has a formation running from Wolf Creek to Canada that’s 40 miles wide — it’s a great place to look for dinosaurs. We did 412 field programs last year.”

Glendive’s Frontier Gateway Museum provides an indoor complement to the outdoor dinosaur wonders of the Hell Creek Formation. Both Makoshika State Park and the privately operated Baisch’s Dinosaur Digs make it possible to find fossils with professional supervision and guidance.

Carter County’s annual “Dino Shindig” on the last weekend of July last year won the Montana Office of Tourism’s Event of the Year award for its efforts. The three-day gathering this July 28-30 features 16 professional paleontologists making presentations and a pitchfork fondue to feed the hungry participants.

Those seeing a similar hands-on opportunity without the sunburn should consult the programs offered at Fort Peck’s Interpretative Center and Museum and Bozeman’s Museum of the Rockies — the most comprehensive collection of dinosaur science in the state.

In 2016, 333,151 people made at least part of the Dinosaur Trail. That’s up 15 percent over the year before, and the best record since the route was laid out in 2005.

“I’m just amazed these little kids come in here and they can pronounce all the names way better than I can,” said Old Trail Museum Director Julie Ameline in Choteau. “They really know their stuff.”
