Yet at the outset of the millennium, three interconnected, troubling challenges confront paleontologists: 1) a shrinking job market, 2) diminishing funding sources, and 3) heightened commercialization of fossils.

What are the challenges to studying fossils?
Explanation: Many fossil records are incomplete because some animals were soft bodied or soft tissue which decays quickly. Also, due to movement of tectonic plates, fossils are destroyed so there are many new fossilised organisms which are destroyed and we don't know about them.
How difficult is paleontology?
Paleontology is a difficult discipline to work in, mainly because there aren't many job prospects. It can be difficult to find a paying job in the field. Many people with paleontology degrees end up doing this as a hobby while working in an environmental firm or oil company.
What are the limitations of paleontology?
There are, however, limitations on the information fossils can supply. Fossilization is an improbable event. Most often, bones and other materials are crushed or consumed before they can be fossilized. In addition, fossils can only form in areas where sedimentary rock is formed, such as ocean floors.
Why is paleontology a dying field?
Paleontology is a tough discipline to work in, there aren't a lot of jobs available and there are still societal pressures that discourage many people from pursuing this science.
How does paleontology affect the environment?
Because the organisms draw the elements for their shells from the ocean water around them, the composition of the shells reflects the current composition of the ocean.By chemically analyzing the shells, paleontologists can determine the amount of oxygen, carbon, and other life-sustaining nutrients in the ocean when the …
What life was on Earth 3.5 billion years ago?
microbes 18), with a new study in the Proceedings of the National Academy of Sciences that uses the latest techniques to date the most aged remains available, confirming the existence of bacteria and microbes nearly 3.5 billion years ago, possibly living on a planet without oxygen.

How long do paleontologists go to school?
As a minimum education requirement, people that want to pursue a career in this field need to get at least a bachelor's degree in paleontology or a related field. Most bachelor programs take four years to complete. Getting a bachelor's degree will enable you to apply for entry-level job positions in paleontology.
What are the challenges of estimating the absolute ages of old fossils?
(A) The three primary challenges are: 1) the easiest, identifying and determining the age of the oldest fossil (FAD); 2) estimating the size of the temporal gap between the FAD and the time of origin of the first fossilizable apomorphy of the lineage (ΔTGap); and 3) estimating the size of the gap between the true time …
