Paleobiology (or palaeobiology) is an interdisciplinary field that combines the methods and findings found in both the earth sciences and the life sciences. An investigator in this field is known as a paleobiologist.
Paleobiology is closely related to the field of paleontology, although the latter focuses primarily on the study and taxonomic classification of , while paleobiology incorporates a broader ecological, evolutionary and geological perspectives of the history of life on Earth. It is also not to be confused with geobiology, which focuses more on the contemporary interactions between the modern biosphere and the lithosphere.
Paleobiological research uses biological field research of current biota and of fossil evidence millions of years old to draw parallel and answer questions about the molecular evolution and the evolutionary history of life. In this scientific quest, , and are typically analyzed. However, the 21st-century biochemical analysis of DNA and RNA samples offers much promise, as does the biometric construction of phylogenetic trees.

Paleobiologists
The founder or "father" of modern paleobiology was Baron Franz Nopcsa (1877 to 1933), a Hungarian scientist trained at the University of Vienna. He initially termed the discipline "paleophysiology".
However, credit for coining the word paleobiology itself should go to Professor Charles Schuchert. He proposed the term in 1904 so as to initiate "a broad new science" joining "traditional paleontology with the evidence and insights of geology and isotopic chemistry."[Schuchert is cited on page 170 of Cradle of Life: The Discovery of Earth's Earliest Fossils (Princeton: Princeton University Press) by J. William Schopf (1999). .]
On the other hand, Charles Doolittle Walcott, a Smithsonian adventurer, has been cited as the "founder of Precambrian paleobiology". Although best known as the discoverer of the mid-Cambrian Burgess Shale animal fossils, in 1883 this American curator found the "first Precambrian fossil cells known to science" – a stromatolite reef then known as Cryptozoon algae. In 1899 he discovered the first acritarch fossil cells, a Precambrian phytoplankton he named Chuaria. Lastly, in 1914, Walcott reported "minute cells and chains of cell-like bodies" belonging to Precambrian purple bacteria.[Walcott's contributions are described by J. William Schopf (1999) on pages 23 to 31. Another good source is E. L. Yochelson (1997), Charles Doolittle Walcott: Paleontologist (Kent, Ohio: Kent State University Press).]
Later 20th-century paleobiologists have also figured prominently in finding Archean and Proterozoic eon : In 1954, Stanley A. Tyler and Elso S. Barghoorn described 2.1 billion-year-old cyanobacteria and fungi-like microflora at their Gunflint Chert fossil site. Eleven years later, Barghoorn and J. William Schopf reported finely-preserved Precambrian microflora at their Bitter Springs site of the Amadeus Basin, Central Australia.[The paleobiologic discoveries of Tyler, Barghoorn and Schopf are related on pages 35 to 70 of Schopf (1999).]
In 1993, Schopf discovered O2-producing blue-green bacteria at his 3.5 billion-year-old Apex Chert site in Pilbara craton, Marble Bar, in the northwestern part of Western Australia. So paleobiologists were at last homing in on the origins of the Precambrian "Oxygen catastrophe".[The Apex chert microflora is related by Schopf (1999) himself on pages 71 to 100.]
During the early part of the 21st-century, two paleobiologists Anjali Goswami and Thomas Halliday, studied the evolution of mammaliaforms during the Mesozoic and Cenozoic eras (between 299 million to 12,000 years ago). Additionally, they uncovered and studied the morphological disparity and rapid evolutionary rates of living organisms near the end and in the aftermath of the Cretaceous mass extinction (145 million to 66 million years ago).
