Prairies and Lakes
The Prairies and Lakes region is in north central and central Texas. This area is a transition between the plains of the West Texas Panhandle and the Pineywoods of East Texas. Patches of woodland running in a north and south direction are sprinkled throughout this grassland prairie. The land is gently rolling to hilly. This region is sometimes called “cross timbers” because these patches of treed areas cross strips of prairie grassland.
The soil here is rich, fertile, and black. Part of this region is called Blackland Prairie because of this. Once, tall prairie grasses grew all across this region but settlers built farms and produce crops on it now. Conservation biologists are trying to restore some of the prairies that wildlife depend upon for survival.
Lake Fork, Lake Ray Roberts, and Cedar Hill State Park are popular state parks here. People who love to fish come from all over Texas and even other states to fish in area lakes.
Giant dinosaurs once roamed this region long, long ago. Fossils of 17 different dinosaurs have been found including Tyrannosaurus Rex! The official state dinosaur of Texas is the Pleurocoelus. The Technosaurus was found near Texas Tech University, hence its name! This dinosaur was no longer than a large dog and was an herbivore (plant eater). The Alamosaurus was named after a New Mexico trading post called “Ojo Alamo” where this dinosaur was first found. “Alamo” is the Spanish word for the cottonwood tree. The Alamosaurus was also an herbivore, however, it swallowed plants whole and let its stomach digest it. This was because its teeth were not suitable for chewing. Dinosaur Valley State Park has the largest collection of dinosaur footprints. You can see dinosaur tracks in the Paluxy River bed at the state park, which is near Glen Rose.
