Many of the fossil was then a visitor at the University of specimens previously assigned to these California. We had many discussions of genera are now known to represen t M eta Metasequoia, the conifer whose discovery sequoia.

Taphonomic and Depositional Analysis of Megaflora of the Cretaceous Hell Creek Formation near Marmarth, North Dakota Mallory Nelson, Chelsea Ames, Will Franta Department of Geoscience, Winona State University, Winona, Minnesota 55987 ABSTRACT The Hell Creek formation of western North Dakota and eastern Montana contains a large variety of plant, pollen, and vertebrate fossils. A high quality plant fossil site near Marmarth, North Dakota was studied to obtain megafloral fossils characteristic of the unit. Plant fossils from the unit were obtained, photographed, and identified so as to obtain a more thorough knowledge of the depositional environment and climate of the region during the Cretaceous period. Fossils identified indicate a forested, deltaic environment rich in water and sediment influx. Introduction been extensively sought after and analyzed by The Hell Creek formation of Western North paleontologists, plant and pollen fossils receive far Dakota and Eastern Montana has long been less study (Johnson, 330). -

Paleocene and Eocene floristic and climatic change in Russia and Northern Kazakhstan MIKHAIL A. AKHMETIEV Paleocene and Eocene floras of Russia and adjacent regions are reviewed with an interpretation of climatic conditions under which they developed. Floristic and climatic changes in western and central regions of Russia in the Paleocene and in the first part of the Eocene were caused by the dynamics and rearrangement of the systems of marine seaways: a longi- tudinal seaway, which connected the Arctic basin with the marginal seas of Northern Peri-Tethys (Turanian, South Rus- sian and others), and a latitudinal seaway, which connected the marginal seas of Northern Peri-Tethys with the Atlantic Ocean. As these systems were progressively reduced, the climate in the middle latitudes changed from paratropical (like in West and Central Europe) to a subtropical monsoon climate with wet summers (Late Ypresian to Lutetian), and later to a climate with wet winters (Late Lutetian to the first part of the Priabonian). Floristic changes reflect these climatic trends. In the Paleogene, cold currents constantly influenced the climate of regions of the northwestern Pacific and facili- tated development of a warm-temperate mesophilic flora. A warmer episode took place in the Early Eocene. At this time thermophilic plants (Sabal, Myrtaceae and Lauraceae) reached Koryakia, North Western Kamchatka, probably as a re- sult of northward migration. Some subtropical plants existed near the Recent Polar circle. The subtropical Raichikha-type Flora lost temperate elements and, by ecological and climatic types, it is more similar to the Recent flora of South-West and South China. -

March 1973 Portland Oregon 97201 THE OLIGOCENE LYONS FLORA OF NORTHWESTERN OREGON Herb Meyer Student, Portland State University The purpose of this study of the Lyons flora is to determine the age and paleoecology of the flora through the examination and identification of the fossil plant species of the flora. The plant fossi Is comprising the Lyons flora were collected from a locality in the .t~~·fi:~ora upper Thomas Creek area, 5 mi les sou theast of the town of Lyons, Oregon. Geologic Occurrence The beds from which the Lyons flora was obtained are part of the Little Butte Volcanic Series of Oligocene and early Miocene age described by Peck and others(1964). Stratigraphically below the fossil deposit, the Little Butte Volcanic Series is characterized by a pumiceous tuff-breccia which contains blocks and fragments of a volcanic flow rock. This exposure, the base of which is not exposed, underlies the fossil deposit for a thickness of more than 400 feet. The deposit containing the fossi I leaves is composed of a thinly lami nated tuffaceous material which has been silicifed to varying degrees. These beds may have been deposi ted in a sha !low, quiet body of water. Lacustrine deposition is suggested by the stratification of the beds, the abundant pres ence of fossil leaves, and the presence of one water plant in the fossil record. Composition of the Lyons Flora Twenty-four identified fossi I plants represent the Lyons flora as it is known at this point in the study. -

Helmut Knoll & Harald Schwanz Mammutbäume – lebende Fossilien Als lebende Fossilien bezeichnet man Lebewe- sen, die schon seit Jahrmillionen auf der Erde leben und sich in diesem langen Zeitraum kaum verändert haben, wie den Quastenfl osser. Es gibt aber auch im Pfl anzenreich lebende Fossilien, die Mammutbäume. In manchen Fällen waren sie schon aus fossilen Funden bekannt, ehe man die ersten lebenden Exemplare wieder entdeckte. Mammutbäume in herrlichen Parkanlagen Viele historische Parkanlagen mit exotischen Bäu- men haben wir dem Adel zu verdanken. Kaiser, Könige und was Rang und Namen hatte, traf sich dort zur Sommerfrische. Sie ließen Schlösser und Villen mit herrlichen Parkanlagen bauen. Man- che dieser Gebäude bestehen heute noch und sind genutzt, andere leider dem Verfall preisgegeben. Die Riesenmammutbäume (Sequoiadendron gigan- teum, 1, 2), gelegentlich auch Berg-Mammutbaum oder Wellingtonie genannt, blieben bestehen, und manche davon sind schon über 150 Jahre alt. Diese findet man relativ leicht. Man muss nur den Kopf und die Augen heben und oberhalb der üblichen Baumhöhen suchen, dann fallen sie auf, denn sie sind majestätisch. Wenn man sie lässt, werden sie zu wahren Giganten der Natur. Auch ist das Ausse- hen ganz speziell, wer darauf achtet, wird die Bäume ebenfalls sofort erkennen. Die Standorte der meis- ten alten Mammutbäume sind europaweit gleich- artig. Immer finden sie sich in Verbindung mit Klös- tern, Schlössern oder Villen, die ab der Mitte des 19. Jahrhunderts erbaut oder renoviert wurden. 1: Ein Riesenmammutbaum Damals herrschte der Modetrend, einen Englischen Sequoiadendron giganteum Park oder einen Schlosspark anzulegen.
