Palynology: What Is It?
Palynology is the study of living and fossilized plant
pollen, spores, and some microscopic plankton organisms, or palynomorphs.
While geologists (palynologists) may use fossil pollen and
spores (paleopalynology) to study past environments, stratigraphy (the analysis
of strata or layered rock), historical geology, and paleontology, botanists use
living pollen and spores (actuopalynology) to study plant relationships and
evolution.
The oil and gas industry is credited with showing that
palynomorphs can be used to study rock stratigraphic sequences and have the
potential to be used in oil and gas exploration. Palynomorphs can be recovered
from rocks and sediments through careful chemical treatment because they are
resistant to decomposition and abundant. This gives scientists the information
they need to describe ancient plant life. Scientists who study the Earth's rock
layers, known as stratigraphers, can correlate rocks of the same age by
describing the sequence of specific palynomorphs through the layers. This
allows stratigraphers to locate and associate layers that contain oil or
natural gas.
Palynomorphs found in the gut or intestinal tract of early
humans and those associated with cultural artifacts (pots, tools, or other
items) discovered at their grave sites have been used to learn about these
early people's diets and hunting methods. For instance, scientists were able to
describe how the diets of native people in northern Chile changed over several
generations using pollen and spores found in the feces of seven
thousand-year-old mummies.
Melissopalynology is the investigation of dust in honey,
determined to distinguish the source plants utilized by honey bees in the
creation of honey. This is important to honey producers because honey made from
pollen and nectar from certain plants, like citrus, buckwheat, mesquite, or
tupelo trees, fetches a higher price than honey made from other plant sources.
Nectar and pollen from some plants may be harmful to human health. These toxic
sources can be identified by carefully monitoring the various pollen types
found in honey, preventing the produced honey from entering the commercial
market.

A survey of atmospheric pollen and spore production and
dispersal (aerobiology), the investigation of human allergies, the
archaeological excavation of shipwrecks, and an in-depth analysis of animal
diets are just a few of the many uses for palynology. The study of pollen on
the body or in the gut of insects is known as entomopalynology. Because it
involves economically important insects like the boll weevil or earwigs, it is
useful for determining their feeding and migratory patterns. Crime Scene
Investigators all over the world use forensic palynology, or pollen analysis,
to solve crimes.
Palynologist:
Palynology is the science of pollen and spore
identification, origin, classification, and distribution. These researchers
understand the formational environments, occurrences, and classifications of
various plant groups. Palynologists can collect these tiny particles and carry
out research to the project's goal. They can create classification charts and
distribution stories as a result of their microscopic studies, as well as
determine their biological and formational origin. Palynologists can decipher a
variety of clues about the conditions of the recent and paleoenvironmental past
by working with fossilized samples or pollen and spores from recent times. The
palynologist in palynology fossil studies extracts and preserves fossilized
pollen and spores using various extraction techniques. The use of these fossils
as correlation agents between various rock groups for environmental comparisons
and geologic age determination is then possible.
Palynology can be broken down into four main subfields.
These are entomopalynology, melissopalynology, paleopalynology, and
criminological palynology. The classification of pollen's depositional
environments and the usage that goes along with them are the primary factors
that go into these classifications.

• The study of the relationship between pollen and insects is known as entomopalynology.
• Melissopalynology investigates honey spores and pollen.
• The study of fossil pollens and spores in paleopalynology
aims to comprehend the formational and depositional environments of the past.
Biostratigraphy is also used to determine the geological age and correlate
stratigraphic rocks. Copropalynology, a sub-branch of paleopalynology, deals
with pollen and spores found in animal coprolites—fossilized biological
excrements—that provide information about the diets of organisms like
prehistoric humans and extinct animals in the near past or archeological past.
• The study of dust-sized particles in associated criminal
cases is known as forensic palynology. Pollen and spores' abundance and a high
potential for preservation shed light on the formational and depositional
environments.
