Amazon.com Paleobotany About 2 pages (627 words) Paleobotany Summary Paleobotany Paleobotany is the study of plants that lived in prehistoric times. It largely involves the study of fossils, that is, impressions of plant parts that have been preserved in sedimentary rock or coal. The most ancient plant fossils are of microscopic algae that lived more than one billion years ago, during Precambrian times. Paleobotanists also study much younger plant fossils, such as pollen in recent lake sediment. One of the goals of paleobotany is to discover the earliest occurrences of different kinds of plants in the geological record. This knowledge of sequential occurrence of taxa is then used to develop an understanding of the evolutionary relationships among groups of plants. Other paleobotanists are interested in determining what fossil plants were like, and the kinds of animals that utilized them as food and habitat. This information can also be used to infer the characteristics of the ancient environment, including the type of climatic conditions in which the plants grew. Sometimes paleobotanical knowledge can be used for quite practical purposes, such as the development of fossil-plant indicators that can be used to help locate underground deposits of coal or petroleum.

You are here: Paleobotany of Angiosperm Origins index bookmark print [ Paleobotany of Angiosperm Origins ] JOHN M. MILLER, PH.D. Having discussed some ideas on the origin of angiosperms from tree- or shrub-like Permo-Triassic seed plant stock, the second part of the web site outlines some of the biodiversity of extinct forms, which might offer some clues on solving the riddle of angiosperm beginnings. A third essay titled, " paleobiogeography of angiosperm origins ," traces seed plant lineages and floras from the Permian Period of Pangaea to continental cratons, fold belts, and island arcs of the Cretaceous Period. The picture of the rock slab to the left is of an indeterminate pentamerous fossil flower (Celastrales, Rosidae) collected by Professor David L. Dilcher from the Lower Cretaceous Dakota Formation of North America. The image was captured in 1981 while the author was visiting Indiana University. The first clue that sheds light on the shadowy origin of flowering plants comes (surprisingly) from study by oil and gas explorers and geochemists of fossilized biomarkers and molecular traces which are recoverable from mud logs of well boreholes.

The oldest widely occurring fossils are various forms of calcareous algae that apparently lived in shallow seas, although some may have lived in freshwater. Their variety is so profuse that their study forms an important branch of paleobotany.

The earliest seedlike bodies are found in rocks of the Late Devonian epoch (374 to 360 million years ago). During the course of the evolution of the seed habit, a number of morphological modifications were necessary. First, all seed plants are heterosporous: two kinds of spores (microspores and... role of: Kidston ...became honorary paleobotanist to the British Geological Survey. In this first period of his work, which lasted until 1904, he studied the floristic, systemic, and stratigraphical characteristics of Paleozoic fossil plants. The high calibre of his research won him wide recognition. He was engaged to prepare catalogs of Paleozoic plants for various institutions, including the British Museum.

25. Fossil Plant Collection: The Geology Department At The Field Museum The paleobotany collections at Field Museum rank fourth or fifth in size nationally The paleobotanical collections at The Field Museum are an important http://www.fieldmuseum.org/research_collections/geology/plants_col.htm

Paleobotany Collection T he paleobotany collections at Field Museum rank fourth or fifth in size nationally with about 77,800 curated specimens that range in geologic age from Precambrian to Pleistocene. The paleobotanical collections at The Field Museum are an important national and international resource for systematic and evolutionary plant biology. In the past five years these collections have grown by over 10% (ca. 7,800 specimens). Of the recent acquisitions, ca. 41% were added through the activities of Field Museum staff and associates, and ca. 59% were added through the acquisition of scientifically important donated collections. Active field work by Field Museum staff, associates and students during this period has resulted in steady growth of the paleobotanical collection. Systematic Coverage- Most groups of plants are wellrepresented in the paleobotanical collections. Particular strengths include a wide array of Carboniferous taxa, and Cretaceous and Paleogene angiosperms. Geographic Strengths- The paleobotanical collections possess nearly worldwide coverage, but are strongest for North American localities. Within North America the collections are especially strong in Paleozoic material from Illinois, Indiana, Iowa, Michigan, Ohio and West Virginia, Mesozoic material from Alaska, Utah, Virginia, Maryland, Georgia and Tennessee, and Cenozoic material from Mississippi, Tennessee, North Dakota, Wyoming, Montana and Colorado. Especially significant localities are described below.

CONIFER PALEOBOTANY BASICS "When you were a tadpole and I was fish, In the paleozoic time, And side by side in the ebbing tide We sprawled through ooze and slime" Evolution. by Langdon Smith There are or have been at least six major orders of the subclass Coniferata ("conifers"), four of which remain today. The first of these orders - - - the Cordaitales - - - flourished as ground creepers, shrubs, mangroves and trees in the great swampy tree fern forests (which formed much of our present day coal deposits) in the Carboniferous and lower Permian Periods, and probably evolved some conifer precursors (maybe including the Voltziales) and then became extinct. The second order - - - the Voltziales - - - flourished during the upper Permian through the Jurassic Periods and was an important transition form, diversifying into all or some of the conifer orders that survive today, before it became extinct. The remaining four orders that are here today include the Gnetales , which exists as non-tree plants including Ephedra, Gnetum and Welwitscia. Another order - - - the

34. Plant Histology: Paleobotany Learn the process of cutting a rock section in paleobotany. http://www.publicbookshelf.com/public_html/Methods_in_Plant_Histology/paleobotan

Plant histology: Paleobotany Paleobotany has made such rapid progress during the last ten years that scarcely any problem involving the anatomy of living vascular plants can be investigated intelligently without some knowledge of Mesozoic and Paleozoic forms. Material, especially that of Paleozoic Pteridophytes and Gymnosperms, is becoming available, and consequently it is increasingly necessary for laboratories to have apparatus and technic for cutting rock-sections. The outline of the process of cutting a rock-section is very simple: 1. Saw the rock into two pieces. 2. Polish the cut surface. 3. Fasten the cut surface to a piece of glass with hot shellac. 4. With the saw, make another cut, as close to the glass as possible, so as to leave a thin section firmly fastened to the glass. 5. Grind and polish until the section is as thin as possible, or as thin as you want it. 6. Wash all polishing powder off with water. 7. Dry completely and, either with or without moistening in xylol, mount in balsam. A word of suggestion in regard to these various points may not be amiss.

36. Paleobotany Of Australia And New Zealand Conifers paleobotany of Australia and New Zealand conifers. http://www.conifers.org/topics/nz_paleo.htm

Paleobotany of Australia and New Zealand conifers Source: All text below this point is quoted verbatim. Pole, M. (1993). Keeping in touch: vegetation prehistory on both sides of the Tasman. Australian Systematic Botany At the end of the Cretaceous New Zealand broke away from the Australian-Antarctic continental mass and was physically isolated by the Tasman Sea. Early in the Tertiary New Zealand moved a long way north relative to Australia, but with the rapid northward movement of Australia, starting in the Eocene, Australia overtook New Zealand, so that much of the South Island of New Zealand now lies south of Tasmania. The northward and relative movements of the two blocks provide an interesting framework for comparing the development of their vegetation. In the Late Cretaceous New Zealand and Australia were physically attached and shared a flora dominated by podocarp and araucarian conifers and deciduous angiosperms, consistent with growth in a polar latitude with periods of winter darkness. When New Zealand broke away and moved north, a typically evergreen angiosperm-dominated flora developed. This showed similarities to the extant and fossil flora of the Australian mainland. To the south, Tasmania developed a quite distinct flora often dominated by conifers.
