What is a transitional fossil? Transitional fossils were poorly adapted to their environments. O Transitional fossils have features that are intermediate between ancestors and descendants. Transitional fossils only existed for a short period of time. A transitional fossil is in the middle of a direct lineage stretching from ancient forms to organisms alive today

Paleontology

A branch of science concerning the scientific study of life from ancient times is known as paleontology. The scientists working on paleontology are known as paleontologists. Paleontologists collect the fossils of organisms from ancient times to classify them. The paleontologists also study the environment from ancient times to study the interactions between different organisms.
