A transitional fossil is a term used to describe a fossil that shows a transitional form of two different species.As the theory states that organisms have gradually changed from one from to another form transitional fossils should be found that show evidence of the transitional forms of the organism.
Transitional fossils are believed to be the preserved evidence of transitional forms of organisms, the so called missing links which provide support to the theory of descent with modification.
