The common denominator among most deposits of fossil insects and terrestrial plants is the lake environment. Those insects that became preserved were either living in the fossil lake (autochthonous) or carried into it from surrounding habitats by winds, stream currents, or their own flight (allochthonous).
The larvae are saprophagic or phytophagous, eating decaying and fresh plant matter. Diopsis macrophthalma Dalman, 1817, is a pest of rice and sorghum in tropical Africa. The peculiar morphology of stalk-eyed flies makes it easy to identify their fossils (e.g. in amber); one fossil genus is Prosphyracephala, known from Eocene aged Baltic amber. [6]
Palynology is also used to date and understand the evolution of many kinds of plants and animals. In paleoclimatology, fossil palynomorphs are studied for their usefulness in understanding ancient Earth history in terms of reconstructing paleoenvironments and paleoclimates. [3] [4]
Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general.
Chemical analysis of soil fossils generally focuses on their lime content, which determines both their pH and how reactive they will be to dilute acids. Chemical analysis is also useful, usually through solvent extraction to determine key minerals. This analysis can be of some use in determining the structure of a soil fossil, but today X-ray ...
Micrographia: or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses. With Observations and Inquiries Thereupon is a historically significant book by Robert Hooke about his observations through various lenses. It was the first book to include illustrations of insects and plants as seen through microscopes.
A troodontid theropod who is known from fossil teeth. Fossils have also been found in the Lance Formation in Wyoming. Pectinodon [96] [95] P. bakkeri [96] [95] Montana; UCM 38445, a fossilized tooth. Teeth of this genus have been found too. A troodontid theropod who is known from fossil teeth. Fossils have also been found in the Lance Formation ...
By far, invertebrate paleozoology is the easiest type of fossil collecting. Unlike the difficult-to-analyze and hard-to-interpret fossils of paleobotany (plants) and micropaleontology (microbes), and unlike the rarely found and poorly preserved skeletons of vertebrate paleontology, invertebrate fossils are usually both common and simple to ...
