John F. AAPG Bulletin ;; 44 1 : Palynology is the study of pollen and spores.

The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e.

Palynology , scientific discipline concerned with the study of plant pollen , spores , and certain microscopic planktonic organisms , in both living and fossil form. The field is associated with the plant sciences as well as with the geologic sciences, notably those aspects dealing with stratigraphy , historical geology , and paleontology. Palynology also has applications in archaeology , forensic science and crime scene investigation, and allergy studies. Accordingly, the scope of palynologic research is extremely broad, ranging from the analysis of pollen morphology with electron microscopes to the study of organic microfossils palynomorphs extracted from ancient coals. As pollen and spores are produced in large numbers and dispersed over large areas by wind and water, their fossils are recoverable in statistically significant assemblages in a wide variety of sedimentary rocks. Moreover, because pollen and spores are highly resistant to decay and physical alteration, they can be studied in much the same way as the components of living plants. Identification of pollen and spore microfossils has greatly aided delineation of the geographical distribution of many plant groups from early Cambrian time some million years ago to the present.

With Palynology We Can See the Tiniest Details

What Is Palynology? Palynology is the study of plant pollen, spores and certain microscopic plankton organisms collectively termed palynomorphs in both living and fossil form. Botanists use living pollen and spores actuopalynology in the study of plant relationships and evolution, 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. The oil industry is credited with demonstrating the usefulness of palynomorphs in the study of stratigraphic sequences of rocks and the potential for oil and gas exploration. Because palynomorphs are resistant to decomposition and are produced in great abundance, their recovery from rocks and sediments via special and careful chemical treatments is possible and provides scientists with information needed to describe plant life of past ages. By describing the sequence of selected palynomorphs through the rock layers of Earth, stratigraphers scientists who study the rock layers of the earth are able to correlate rocks of the same age and may therefore locate and correlate layers that contain oil or natural gas.

Palynology, which is the study of pollen and spores in an archaeological or geological context, has become a well-established research tool leading to many significant scientific developments. The term palynomorph includes pollen of spermatophytes, spores of fungi, ferns, and bryophytes, as well as other organic-walled microfossils, such as dinoflagellates and acritarches. Advances in plant genomics have had a high impact on the field of forensic botany. Forensic palynology has also been used and applied more recently to criminal investigation in a meaningful way. However, the use of pollen DNA profiling in forensic investigations has yet to be applied. There were earlier uses of dust traces in some forensic analyses that considered pollen as a type of botanical dust debris. Pollen grains can be studied for comparative morphological data, clues to unexpected aspects relating to breeding systems, pollination biology and hybridization.

Palynology - the study of micro organic material such as spores, pollen, dinoflagellates and microfossils 1 - is a method employed by a range of disciplines all concerned with the environment. It is not an undergraduate degree subject due to its limited scope, and though there are some Master's programmes in most countries, those wishing to enter into the field may approach the subject from many different directions. One of the most fascinating aspects - and perhaps underappreciated by most people - is how landscapes change over time in terms of the plant life that grows there. We can learn much about the landscape itself, the natural and human history of that landscape including the changes it has undergone as a result of natural or human processes , and of the changing climate and what impact that has upon plant life. Flora - trees, flowers, grasses, mosses, lichen and even fungi have environmental conditions that they prefer and other conditions in which they will not survive for very long.

A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age.
