The Clinchfield Formation is a geologic formation in Georgia. It preserves fossils dating back to the Paleogene period. It preserves the most diverse Eocene fossil turtle assemblage in all of southeastern North America. [1]
Georgiacetus is an extinct genus of ancient whale known from the Eocene period of the United States. Fossils are known from Georgia, Alabama, and Mississippi and protocetid fossils from the right time frame, but not yet confirmed as Georgiacetus, have been found in Texas and South Carolina.
Bahndwivici is an extinct genus of lizard known from a nearly complete and articulated skeleton discovered in rocks of the Green River Formation of Wyoming, United States. The skeleton is very similar to that of the modern Chinese crocodile lizard, Shinisaurus.
Afairiguana avius is an extinct iguanid lizard known from a nearly complete and articulated skeleton discovered in rocks of the Early Eocene-aged Green River Formation of Wyoming, United States. As of the initial description, the skeleton represents the oldest complete iguanian from the Western Hemisphere, and is the oldest representative of the extant iguanid family of anoles, Polychrotidae.
Echmatemys is an extinct genus of geoemydid turtle from the Eocene of North America. It is the oldest North American geoemydids, and is one of the most common early Eocene turtles.
Paleontology in Florida refers to paleontological research occurring within or conducted by people from the U.S. state of Florida. Florida has a very rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.
Paleontology in Alabama refers to paleontological research occurring within or conducted by people from the U.S. state of Alabama. Pennsylvanian plant fossils are common, especially around coal mines. During the early Paleozoic, Alabama was at least partially covered by a sea that would end up being home to creatures including brachiopods, bryozoans, corals, and graptolites. During the Devonian the local seas deepened and local wildlife became scarce due to their decreasing oxygen levels.
Aphaenogaster donisthorpei is an extinct species of ant in formicid subfamily Myrmicinae known from a Late Eocene fossil from North America. A. donisthorpei was one of two Aphaenogaster species described in the 1930 paper.
The Hatchetigbee Bluff Formation is a geologic formation in Alabama, Georgia, Louisiana and Mississippi. The youngest unit of the Wilcox Group preserves fossils dating back to the Ypresian stage of the Eocene period, or Wasatchian in the NALMA classification. The formation is named for Hatchetigbee Bluff on the Tombigbee River, Washington County, Alabama.
The Conasauga Formation is a geologic formation in Georgia. It preserves fossils dating back to the Cambrian period.
The Ash Hollow Formation of the Ogallala Group is a geological formation found in Nebraska and South Dakota. It preserves fossils dating back to the Neogene period. It was named after Ash Hollow, Nebraska and can be seen in Ash Hollow State Historical Park. Ashfall Fossil Beds State Historical Park is within this formation.
The Sharps Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Paleogene.
The White River Formation is a geologic formation of the Paleogene Period, in the northern Great Plains and central Rocky Mountains, within the United States.
The Washakie Formation is a geologic formation in northern Colorado and southern Wyoming. It preserves many mammal, bird, reptile and other fossils dating back to the Lutetian stage of the Eocene within the Paleogene period. The sediments fall in the Bridgerian and Uintan stages of the NALMA classification.
The Hoback Formation is a geologic formation in west-central Wyoming, located within the Hoback Basin. It formed as a result of increased sedimentation rates from the Laramide Orogeny and preserves fossils dating back to the late Paleogene period, through the early Eocene.
The Bridger Formation is a geologic formation in southwestern Wyoming. It preserves fossils dating back to the Bridgerian and Uintan stages of the Paleogene Period. The formation was named by American geologist Ferdinand Vandeveer Hayden for Fort Bridger, which had itself been named for mountain man Jim Bridger. The Bridger Wilderness covers much of the Bridger Formation's area.
The Puget Group is a geologic group in Washington (state). It preserves fossils dating back to the Paleogene period.
Aphaenogaster mayri is an extinct species of ant in formicid subfamily Myrmicinae known from a series of Late Eocene fossils found in North America. A. mayri was one of two Aphaenogaster species described in a 1930 paper by Frank M. Carpenter.
The Oldhaven Formation is a geologic formation in England, outcropping near Herne Bay, Kent. According to Philip Hadland, it preserves finely preserved fossils, such as those belonging to birds, fishes, snakes and turtles, dating back to the Eocene epoch (Ypresian).
Priabona is an extinct genus of big-headed flies in the dipteran subfamily Nephrocerinae, within which it is one of only two genera. The genus contains a single described species, Priabona florissantius. Priabona is known from a single Late Eocene fossil from western North America.
Tasbacka is an extinct genus of sea turtle containing several species.
