The reproductive cycle extends over 19-20 months from pollination in October to seed maturity in February or March of the second year following ( Owens et al. "A tree twenty-five to thirty years old may begin to bear fertile seeds. When the female cone is ripe the scales open, releasing the winged seeds which are borne away by the wind. Seeds remain viable for only a short period, and usually germinate when they settle in an open situation where light can penetrate readily. "The spreading crown of the kauri is, relative to the trunk, immense; it is rather open as the tree ages and is supported on huge branches that appear simply to swell out of the upper trunk. The first or lower of these branches can be up to 2 m through where they leave the trunk. Kauri trees are rather slow growing over their life span although young trees have been recorded as growing at the rate of 0.35 m per year. ... Young kauri trees ... are known as “rickers”. They persist in this juvenile form for fifty years or more and can attain a considerable height with their tall thin trunks and narrow pyramid shaped crowns. Eventually [they] will shed their lower branches, and as their slender trunks and narrow crowns expand they will assume the shape of the mature tree" (

A Brief Introduction to PALEOBOTANY Although most of the "green things" that populate our oceans and continents don't have the ability to move about and, hence, grab out attention, the world's biota couldn't exist without these organisms. The Plant Kingdom is the base of Earth's food chain and, as such, is the foundation for all life as we know it today, in the recent past, and in the deep past. That's not to say that today's biota is exactly like that of the past. Indeed, there have been dramatic changes in the base of the food chain since its first appearance. Documentation of these changes and understanding the reasons for these changes is only part of what Paleobotany - the study of fossil plants sensu latu (in the broad sense) - attempts to do. Those scientists who actively pursue study of these seemingly "uninteresting" organisms have devised several approaches to examine life's history that can be separated into two broad categories TRADITIONAL and INTEGRATIVE APPROACHES. Traditional approaches follow methodologies established during and immediately after the Renaissance, while Integrative approaches are based upon methodologies that could only be established following advances in technology of the 20 th Century. Advances in analytical techniques in the next several decades will, once again, change the way in which we approach this and other disciplines but, the traditional approaches will remain basic to all avenues of research. If you don't know how it was preserved, what it is, how it is constructed, and what is its life cycle, you can't take the organism(s) and use it with any amount of credibility for more synthetic approaches in our desire to develop local, regional, and global models of how Earth works.

Research at the Paleobotany Laboratory at Weston focuses on the evolution of early land plants. We are particularly interested in the fossil evidence surrounding the origin of terrestrial plants, the bulk of this evidence comes from the study of cryptospores, spore-like palynomorphs that pre-date the occurrence of macroscopic land plants. Research projects involve cryptospores, acritarchs, spores and pollen, and early land plant problematica, such as the Nematophytales. Other ancillary technical projects associated with palynological study include computer application development for the study of spore shape and digital Infrared microscopy. Research Projects Recent News Personnel Research Projects The Arisaig Project Silurian Palynology of the central Applachians This project involves field and laboratory studies of Silurian spores and algal cysts from mostly middle and upper Silurian units in Pennsylvania to Virginia. We are examining spores of the early land plants and creating a record of their remains for the first time from these shallow shelf to near shore environments. The results compare favorably with other sections described from the Welsh Basin, Prague Basin and Avalonia. It was during the middle to upper Silurian interval that the tracheophytes (vascular plants) most probably evolved. Through the study and classification of spore remains, we are able to document the origin and early diversification of this important evolutionary event which lead to the establishment of life in the subaerial terrestrial surface. The project was sponsored by the National Science Foundation. Click to view

Paleobotany/Palynology Image Gallery The FLMNH Paleobotanical Collection includes approximately 105,000 specimens. This is a conservative estimate that does not take into account the fact that an individual hand sample may contain more than one fossil of interest. In addition, the facility houses the John W. Hall paleobotanical collection (approximately 20,000 specimens) currently on a long-term loan from the University of Minnesota. The collection is international in scope, ranging from the Proterozoic to the Pleistocene, and including collections from 26 countries. Particular strengths of the collection are: Cretaceous of the US western interior (~17,000 specimens), Cretaceous and Eocene of southeastern North America (~31,000 specimens), Eocene and Oligocene of the Pacific northwest (~19,500 specimens), and Pennsylvanian of Indiana and Illinois (~6,000 specimens). Systematically the greatest strength of the collection is in Cretaceous-Tertiary angiosperms, which are represented by large numbers of well-preserved fruits and flowers as well as leaves and wood. A majority of publications generated by the collection have dealt with angiosperm systematics, but publications also have been generated on algae, fungi, lycopods, ferns, seed ferns, conifers, and insect mines and have been used to address questions of phylogeny, paleogeography, and paleoclimate.

Tissue differentiation, such as modification of lower portions of algae into anchoring holdfasts: Proterozoic Era, 700 mya 6. Encapsulation (development of protective tissue around the fertilized egg, or zygote): Proterozoic Era, 650 mya 7. Subaerial aboveground modifications in Cooksonia, one of the first plants with vascular (conductive) tissues(a) primitive telome (plant body); (b) cortical aboveground support (stiffened outer tissues); (c) xylem conductive tissues; (d) free release of like spores (homospory); (e) cuticle (waxy outer covering to reduce moisture loss) and stomates (special pores for the release of gases): Late Silurian Period, 400 mya 8. Major evolutionary developments(a) endodermis (inner protective layer around conductive tissues); (b) conduction of fluids and the transpiration of gases; (c) absorption by rhizoids (threadlike structures functioning as roots); (d) origin of sporophylls (spore-bearing leaves); (e) plant-body emergences that became leaves; (f) monopodial branching (side branches arising from a continually growing main shoot); (g) origin of roots; (h) branch systems that became leaves; (i) free release of unlike spores (heterospory); (j) internal xylem tissue system of plant support; (k) secondary tissues (xylem and cortex); (l) seminal (seed) forerunner structures: Devonian Period, 390 to 340 mya

Highlights Paleobotany Melanie Devore and Kathleen Pigg This story is expanded from the print version. Paleobotany continues to produce a wealth of anatomical, morphological, and systematic studies as well as floristic descriptions, all of which have always been at the heart of the discipline. Significant this year is the publication of Fossil Flora and Stratigraphy of the Florissant Formation, Colorado (Evanoff and others, 2001, Denver Museum of Nature and Science). This volume updates varied aspects of this important Tertiary site, including megafossils, pollen, and wood (papers by E. Leopold and S. Clay-Poole, F. Wingate and D. Nichols, S. Manchester, E. Wheeler) as well as stratigraphy, paleoclimate, and paleoelevation interpretations (E. Evanoff and others, K. Gregory-Wodzicki, H. Meyer). In 2001, paleobotany continued to expand its traditional boundaries to include studies integrating data from fossil plants in order to understand extinction events, past communities, and paleoclimate. Ancient carbon cycles and carbon-dioxide levels Fossil plant data are proving to be invaluable for estimating past carbon-dioxide levels and providing insights on the functioning of ancient carbon cycles. Paleontological data for the diversity of marine animals and land plants was integrated elegantly with a concurrent measure of stable carbon-isotope fractionation for the last 400 million years (D.H.
