Wibaux in Wibaux County, Montana — The American West (Mountains)
Welcome to Dinosaur Country
Montana's big sky drew tourists even during the darkest days of the Great Depression in the 1930s. Thousands of people came to Montana to enjoy its wide open spaces and experience its Old West heritage. Good roads and cheap gasoline helped make it possible. The Montana Department of Transportation distributed colorful highway maps and brochures at ports of entry stations and information centers. Beginning in 1935, the MDT installed interpretive markers at roadside picnic areas to tell readers about Montana's exciting history. The signs told stories reminiscent of cowboys spinning yarns to a greenhorn. Over 250 roadside signs still introduce visitors and residents to Montana's history and geology.

• American Museum of Natural History paleontologist Barnum Brown discovered the first Tyrannosaurus rex fossil in eastern Montana in 1903. Since then, at least 24 partial Tyrannosaurus skeletons have been discovered in Montana.
• Discovered near Bridger, Montana in 1964, Deinonychus fossils suggested to paleontologists that some dinosaurs were warm-blooded and are the ancestors of today's birds.
• About 65 million years ago, the Western Interior Seaway receded as the Rocky Moutains rose, pushing the shorelines farther east. Great rivers meandered through the coastal plain in a warm and humid climate, depositing sediment which would later become known as the Hell Creek Formation. Dinosaur fossils are frequently found in the Hell Creek Formation.
• Imagine eastern Montana 65 million years ago when it was much different. Instead of heard of cattle, enormous herds of Triceratops and hadrosaurs (sic) roamed the area. Pterosaurs soared across the sky instead of birds. What kind of predators searched for prey in this days?
