Palynollgy in the field was kindly provided by Dean A. It is no surprise that with such abundance and diversity in the more recent fossil record Evitt, dinoflagellates represent one of the major branches of study by palynologists and are especially useful in describing the dynamics of Mesozoic and Cenozoic oceans Palynoolgy et al. Shrubby gymnosperms are represented, indicating deposition in a calm aqueous environment where palyno- morphs could settle and get buried. Dinoflagellates Dinoflagellates are motile unicellular algae characterized by a pair of flagellae. Ideal facies usually correspond to fine-grained mudstone or silty mudstone.
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. Moving from a dry to wet climate or vice versa , from temperate to ice age or vice versa and even whether and when a piece of land was once tidal salt marsh but is now pasture, can all affect the makeup of the landscape's flora. One of the most useful extant remains of a plant that will survive under certain conditions is its pollen or spores.
