2.Gravel Fossils - Paleozoic marine fossils found in the chert gravel that
characterizes the Citronelle Formation (Upland complex) of Louisiana.
3. Tertiary Fossils - Marine fossils found within Tertiary marine
units that outcrop within northern and central Louisiana.
3. Vertebrate FossilsMastodon
Pleistocene, 10,000 to 1.8 million years BP (mastodons, mammoths, and others)
Pliocene, 1.8 to 5.2 million years BP (horses)
Miocene, 5.2 to 23.7 million years BP (ancestral elephants, horses, and many other types)
Oligocene, 23.7 to 36.6 million years BP (bird tracks and sharks teeth)
Primitive Eocene Whales
Eocene, 36.6 to 57.8 million years BP (primitive whales, i.e. Basilosaurus)
Paleocene, 57.8 to 66.4 million years BP
Mesozoic (Cretaceous), 66.4 to 144 million years B.P.
Geologic Map of Louisiana is modified from the "The Generalized Geologic Map of Louisiana, 1990."

6. Geological Time ScaleGeologic Time Scale Figure and Discussion.
Terms such as "Pleistocene," "Pliocene," "Miocene," "Oligocene," "Eocene," and "Paleocene" given above refer to a few of many periods of relative time, from younger to older, that compose the Geologic Time Scale. These periods and other units of geologic time are units of relative time that scientists have subdivided the geologic history of the Earth on basis of the differing fossil assemblages they contain. Because these periods were named and ordered prior to the development of the theory of evolution and radiometric dating, the relative age of these periods to each other was based upon relationships (most commonly, vertical/stratigraphic position) that geologists repeatedly observed in outcrops.
