The Glen Rose Formation is a shallow marine to shoreline geological formation from the lower Cretaceous period exposed over a large area from South Central to North Central Texas. The formation is most widely known for the dinosaur footprints and trackways found in the Dinosaur Valley State Park near the town of Glen Rose, Texas, southwest of Fort Worth and at other localities in Central Texas.

The Paluxy River, also known as Paluxy Creek, is a river in the U.S. state of Texas. It is a tributary of the Brazos River. It is formed by the convergence of the North Paluxy River and the South Paluxy River near Bluff Dale, Texas in Erath County and flows a distance of 29 miles (47 km) before joining the Brazos just to the east of Glen Rose, Texas in south central Somervell County.
