One single definition that defines paleontology is the study of past events with the help of fossils that have been discovered. But if we conduct a depth research, we will surely come to know that paleontology covers many other areas of study and it is beyond the findings on the past events.
When we use the word past, it seems like an enigma because we hardly know what happened, how things were at that time and how the transformation in the environment took place. But science has made it easy to re-locate the past events and get knowledge of past lives on the earth. Hence, all these study is covered under the major field of paleontology.
Before going deeper in understanding paleontology, it is important to have clear idea on fossils because paleontology and fossil are the two related term in science. Fossils are the remains of animals or plants that survived years ago which are found in the form of impressions. Thus, to learn about past events we must have some proof, only then the research work can progress further. Without any evidence, the finding would go meaningless and no hypothesis or research can come out to be effective. Fossils are therefore the evidence that tells the date, time, places of the event that have occurred.
Paleontology is concerned with all the forms of life whether its plants, animals or human beings. Therefore, the study that is conducted using fossils as the solid medium of confirmation can be called as paleontology. Paleontology is not all about studies of past events, rather to study those events and compare all the possible changes that have taken place, also comes under the sub-head of paleontology.
The person who does major in this field is called paleontologist. There are several sub- fields of paleontology and these fields have their name as per the fossil that has been traced. Some of these fields include:
Paleobotany: Botany means study of plants; hence this area is concerned with the study of plant fossil.
Micropaleontology: Micro means the smaller organism. Hence, this area is concerned with the study of fossil of miniature organisms.
Invertebrate paleontology: Invertebrates are the organisms that have no backbones in their body. Hence, invertebrate paleontology is the study of fossil of invertebrate.
Vertebrate paleontology: Vertebrates are the organism having backbone and study of their fossil is called vertebrate paleontology.
Human paleontology: The study of human race with the help of fossils is termed as human paleontology.
Study of fossil is not only based on the morphological appearance rather chemical and biochemical studies are combined with the paleontological data’s to get more of the detailed information’s. Presently, the progress in science has added even the depth to the research work keeping the genes, DNA, mitochondria under the major tools of study. So, students can pursue this field if they love discovering the past events and activities. There are few major tasks that are done by paleontologist which includes the following:
These are some of the works that a paleontologist does thus, unfolding the mystery and adding some newly discovered information’s in this field.
Student can find a satisfying and good job opportunity in this field which includes teacher, lecturer, researcher, museum, or state survey etc. It can be little tough and struggling to get a job in quick time period, but once settled students can surely aspect a good pay.
