From the publisher:
Dinosaurs, space travel, the Civil War, and the wild west, all mixed together in one epic world!
The World of Broncosaurus Rex
In the year 2202, dinosaurs have been discovered on the planet Cretasus. But these dinosaurs are just as smart as the humans now flocking to their home. Velociraptors trade in alien weapons, leptoceratops guard their desert secrets, and T-rex dynasties protect their nests from egg raiders. Despite the dinosaurs, human pioneers arrive in droves at New Savannah's busy spaceport. Lured by free land, gold, and simple freedom, they yearn for a new life. Their wagon trails soon trudge west on the rutted path of the Tecumseh Trail, bringing new adventures to Cretasus.
Dinosaur Planet: Broncosaurus Rex is a science fiction world setting. The basic premise is that the Civil War did not end as we know it, but resulted in separate Federal and Confederate nations. This state continued into the space age. In the year 2202, an alien planet full of dinosaurs was discovered, opening new mysteries and establishing the world of Dinosaur Planet: Broncosaurus Rex.
Your character could be a bronco rider, riding the dinosaurs for ranchers, farmers, the military, or pure adventure. You could be a soldier: a Union ironclad pilot, a federal sheriff, or a rebel blockade runner. You could be a street fighter come to find your fortune, or a homeworld dissident fighting for freedom. You could be one of the legendary Wild Ones, fearsome humans who leave human company to sleep with the dinosaurs. You could be a Union machinist, always equipped with the latest technology. You could be an idealistic infantryman, a freelance dino hunter, a warp pirate, a Union turncoat, an outer ranges explorer, a dino rustler, or an alien hunter. The world of Broncosaurus Rex is in your hands!
