A palaeontologist is a scientist who studies the history of life on earth.
They study the history of life on earth with the help of fossil records as fossils are the evidence of past life on the planet and they can include animal bodies or their imprints.
These are of three types:
Micropaleontologist
These are the scientists who study micro fossils.
Micro fossils are those fossils that require the use of microscope to see the organism, its morphology and its characteristics in detail.
These tiny fossils are found in great number in most of the sedimentary basins.
Paleoanthropologist
The scientists study the human evolution with the help of fossils and archaeological records.
They seek to understand the early anatomically modern humans.
Vertebrate and Invertebrate Paleontologists
The scientists which deal with the study of ancient animal life and how it developed.
They examine the vertebrate and invertebrate animals that live today to study their development.
