Uintah County is a county in the U.S. state of Utah. As of the 2020 United States Census the population was 35,620. Its county seat and largest city is Vernal. The county was named for the portion of the Ute Indian tribe that lived in the basin.
Vernal, the county seat and largest city in Uintah County, is in northeastern Utah, approximately 175 miles (280 km) east of Salt Lake City and 20 miles (32 km) west of the Colorado border. As of the 2020 census, the city population was 10,079. The population has since grown to 10,432 as of the 2022 population estimate.
The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season. Each pair of layers is called a varve and represents one year. The sediments of the Green River Formation present a continuous record of six million years. The mean thickness of a varve here is 0.18 mm, with a minimum thickness of 0.014 mm and maximum of 9.8 mm.
Dinosaur National Monument is an American national monument located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa rivers. Although most of the monument area is in Moffat County, Colorado, the Dinosaur Quarry is located in Utah, north of the town of Jensen, Utah. The nearest Colorado town is Dinosaur while the nearest city is Vernal, Utah.

The Uinta Basin is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division. It is also a geologic structural basin in eastern Utah, east of the Wasatch Mountains and south of the Uinta Mountains. The Uinta Basin is fed by creeks and rivers flowing south from the Uinta Mountains. Many of the principal rivers flow into the Duchesne River which feeds the Green River—a tributary of the Colorado River. The Uinta Mountains form the northern border of the Uinta Basin. They contain the highest point in Utah, Kings Peak, with a summit 13,528 feet above sea level. The climate of the Uinta Basin is semi-arid, with occasionally severe winter cold.
The Arizona Museum of Natural History located in Mesa, Arizona, is the only natural history museum in the greater Phoenix area. It exhibits the natural and cultural history of the Southwestern United States.
The Dinosaur Diamond is a 486-mile (782 km) scenic and historic byway loop through the dinosaur fossil laden Uinta Basin of the U.S. states of Utah and Colorado. The byway comprises the following two National Scenic Byways:
The Prehistoric Museum, USU-Eastern, formerly known as the College of Eastern Utah Prehistoric Museum, is a museum accredited by the American Alliance of Museums located in Price, Utah. The museum seeks to promote public understanding of prehistory through interpretive exhibits, educational programs, collections, and research. The museum is located near many paleontological and archaeological sites in a region known as Castle Country, notably in the San Rafael Swell and nearby canyons throughout the Book Cliffs area such as Nine Mile Canyon and Range Creek Canyon.
Red Fleet State Park is a state park of Utah, United States, featuring a 750-acre (300 ha) reservoir and a fossil trackway of dinosaur footprints. The park is located 10 miles (16 km) north of Vernal.
Steinaker State Park is a state park and reservoir in Uintah County, Utah, United States, located 7 miles (11 km) north of Vernal.
Dinosaur Ridge is a segment of the Dakota Hogback in the Morrison Fossil Area National Natural Landmark located in Jefferson County, Colorado, near the town of Morrison and just west of Denver.
The Mowry Shale is an Early Cretaceous geologic formation. The formation was named for Mowrie Creek, northwest of Buffalo in Johnson County, Wyoming.
Paleontology in Utah refers to paleontological research occurring within or conducted by people from the U.S. state of Utah. Utah has a rich fossil record spanning almost all of the geologic column. During the Precambrian, the area of northeastern Utah now occupied by the Uinta Mountains was a shallow sea which was home to simple microorganisms. During the early Paleozoic Utah was still largely covered in seawater. The state's Paleozoic seas would come to be home to creatures like brachiopods, fishes, and trilobites. During the Permian the state came to resemble the Sahara desert and was home to amphibians, early relatives of mammals, and reptiles. During the Triassic about half of the state was covered by a sea home to creatures like the cephalopod Meekoceras, while dinosaurs whose footprints would later fossilize roamed the forests on land. Sand dunes returned during the Early Jurassic. During the Cretaceous the state was covered by the sea for the last time. The sea gave way to a complex of lakes during the Cenozoic era. Later, these lakes dissipated and the state was home to short-faced bears, bison, musk oxen, saber teeth, and giant ground sloths. Local Native Americans devised myths to explain fossils. Formally trained scientists have been aware of local fossils since at least the late 19th century. Major local finds include the bonebeds of Dinosaur National Monument. The Jurassic dinosaur Allosaurus fragilis is the Utah state fossil.
Billie Untermann (1906–1973) was a geologist who had a significant contribution to the understanding and recognition of the Uintah Basin. She was the single author of the text "The Uinta Basin—Past and Present." This text highlighted the history of the Uinta Basin, which is a stretch of land in Utah which was first colonized 15,000-20,000 years ago. She received her B.A. in geology (1929) and later an M.A.(1934) at the University of California (1934). She discovered and assembled many dinosaur skeletons, which were a popular attraction at the Utah Field House of Natural History, to which she was a museum technician. She eventually become its director.
Earl Douglass was an American paleontologist who discovered the dinosaur Apatosaurus, playing a central role in one of the most important fossil finds in North America. By 1922 Earl had unearthed and shipped more than 700,000 pounds of material including nearly 20 complete skeletons of Jurassic dinosaurs such as Diplodocus, Dryosaurus, Stegosaurus, Barosaurus, Camarasaurus and Brontosaurus.
Tianjin Natural History Museum is in Tianjin, China, and is located in No. 31 Youyi Road, in the Hexi District. It was founded in 1914 as the Hoangho Paiho Museum. The museum has three floors and spans an area of 12,000 square meters. Over 380,000 geological and biological specimens are currently held at the museum.
