Indigenous fossil legends also frequently show motifs resembling major themes in scientific paleontology like deep time, extinction, change over time and relationships between different life forms. [3] Fossils have been used by Native Americans for evidence about the past, healing, personal protection, and trade. [4]
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
These three-dimensional fossils create permanent molds of internal structures. The mineralization process helps prevent tissue compaction, distorting organs' actual size. A permineralized fossil will also reveal much about an organism's environment and the substances found in it since it preserves soft body parts.
Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [57] Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time.
The remainder of the Paleozoic was a time of significant geologic upheaval in the state. There are no sedimentary rocks from this interval of time in which fossils could have been preserved. [2] North Carolina has very few Cambrian fossils. The only known fossils from this time period is the tube-shaped trace fossil Skolithos.

1812 - Cuvier draws skeletal reconstructions of "Palaeotherium" minor (= Plagiolophus minor), "Anoplotherium medium" (= Xiphodon gracilis), and, most famously, Anoplotherium commune based on known fossil remains (of which A. commune was the most nearly complete) and publishes them in his 1812 summary of fossil mammals from Paris.
Deinosuchus fossils have been described from 12 U.S. states, including Texas, Montana, and many along the East Coast. Fossils have also been found in northern Mexico. It lived on both sides of the Western Interior Seaway, and was an opportunistic apex predator in the coastal regions of eastern North America.
