They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
As there are thousands of fossils, mostly fragmentary, often consisting of single bones or isolated teeth with complete skulls and skeletons rare, this overview is not complete, but shows some of the most important findings. The fossils are arranged by approximate age as determined by radiometric dating and/or incremental dating and the species ...

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 ...
Most states in the US have designated a state fossil, many during the 1980s. It is common to designate a fossilized species, rather than a single specimen or a category of fossils. It is common to designate a fossilized species, rather than a single specimen or a category of fossils.
