The Strawn Formation is a geologic formation in Texas and New Mexico. According to Cummins (1891), the formation was named from the town of Strawn in Palo Pinto County, Texas. [1] It preserves fossils dating back to the Carboniferous period.
The Navarro Group is a geologic group in Arkansas, Texas and Coahuila, Mexico. It preserves fossils dating back to the Cretaceous period.
The Morrow Formation is a geologic formation from the Pennsylvanian geological age that is found in locations ranging from Southeast New Mexico and West Texas to locations in Oklahoma, Southwestern Kansas, and Arkansas. It preserves fossils dating back to the Carboniferous period.
The Del Rio Formation is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Taylor Marl is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Atco Formation is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Benevides Formation is a geologic formation in Texas and Mexico. It preserves fossils dating back to the Cretaceous period.
The Escondido Formation is a geologic formation in Texas and Coahuila, Mexico. It preserves fossils dating back to the Late Cretaceous period.
The Goodland Limestone or Goodland Formation is a geologic formation in Arkansas and Texas. It preserves fossils dating back to the Cretaceous period.
The Admiral Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period.
The Belle Plains Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period.
The Vale Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period. Diplocaulus recurvatus is one of the creatures discovered there.
The Nocona Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period.
The Petrolia Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period.
The Oakville Formation is a geologic formation in Texas. It preserves fossils dating back to the Neogene period.
The Stone City Formation is a geologic formation in Texas. It preserves fossils dating back to the Paleogene period. Now known as Stone City Bluff in Burleson County, Texas, it is a special location on the Texas Gulf Coast Plain. It is the best of relatively few places where marine rocks of Paleogene age are exposed and available for public access. This access provides a window into Middle Eocene rocks that were deposited in the Gulf of Mexico approximately 41.8 million years ago.
The Devil's Graveyard Formation is a geologic formation in Texas. It preserves fossils dating back to the Paleogene period.
The Yegua Formation is a geologic formation in Texas. It preserves fossils dating back to the Paleogene period.
The Camp Springs Formation is a geologic formation in the Dockum Group of Texas. It preserves fossils dating back to the Late Triassic. It has also been known as the Camp Springs Conglomerate or Camp Springs Member. The unit was originally named for an unknown locality in West Texas, and was later used in reference to sandstone and conglomerate deposits in Scurry County. It is likely equivalent to the basal beds of the Santa Rosa Formation, and some authors have suggested abandoning the usage of the term "Camp Springs Formation" and similar names.
The Strawn Group is a geologic group in Texas. It preserves fossils dating back to the Carboniferous period.
The Malone Formation is a geologic formation in Texas. It preserves fossils dating back to the Jurassic period.
