In September 1975, Huddle had completed. the posttechnical review copy of his manuscript and had forwarded it for U.S. Geological Survey publica­ tion approval. I received the edited manuscript in September 1976, for review of accuracy of taxonomy and of technical matters and details noted by the Survey editors and by myself. My contribution consisted of checking for, and correcting where necessary, objective errors in the manuscript. In making necessary changes, I relied on Huddle's most recent worksheets, notes, and notes on specimen slides as much as possible in order to preserve the integrity of his work. No changes were made in subjective matters of taxonomy or of interpretation. Throughout my efforts on this paper, I have tried to avoid making any changes that would have affected Huddle's substance or style, so that this published report would be as· much as possible John Huddle's original work.

New field work in outcrops of the Ukhta Region (Southern Timan) together with the re-exanimation of former collections allows a detailed revision of the ammonoid zonation in one of the classical Frasnian regions of Russia. There is a total of 47 species, 18 of which are new or recorded for the first time from the region. The latter applies to representatives of Linguatornoceras, Phoenixites, Aulatornoceras s.str. and Acantho- clymenia. New taxa are Chutoceras manticoides n.gen. n.sp. and Linguatornoceras yudinae n.sp. In the Ust’yarega Formation regional Hoeninghausia nalivkini, Timanites keyserlingi and Komioceras stuckenber- gi Zones can be recognized which correlate with the international Frasnian divisions UD I-B/C.

D. Eberlein, Michael Churkin, Jr., Claire Carter, H. C. Berg, and A. T. Ovenshine Introduction This report consists of the following: 1) Geologic map (1:250,000) (Fig. 1); includes Figs. 2-4, index maps 2) Description of map units 3) Map showing key fossil and geochronology localities (Fig. 5) 4) Table listing key fossil collections 5) Correlation diagram showing Silurian and Lower Devonian facies changes in the northwestern part of the quadrangle (Fig. 6) 6) Sequence of Paleozoic restored cross sections within the Alexander terrane showing a history of upward shoaling volcanic-arc activity (Fig. 7). The Craig quadrangle contains parts of three northwest-trending tectonostratigraphic terranes (Berg and others, 1972, 1978). From southwest to northeast they are the Alexander terrane, the Gravina-Nutzotin belt, and the Taku terrane. The Alexander terrane of Paleozoic sedimentary and volcanic rocks, and Paleozoic and Mesozoic plutonic rocks, underlies the Prince of Wales Island region southwest of Clarence Strait. Supracrustal rocks of the Alexander terrane range in age from Early Ordovician into the Pennsylvanian, are unmetamorphosed and richly fossiliferous, and aopear to stratigraphically overlie pre-Middle Ordovician metamorphic rocks of the Wales Group (Eberlein and Churkin, 1970).

Conodont elements are interpreted as parts of a feeding apparatus, which together with the presence of eyes and microwear patterns, support the controversial hypothesis that conodont animals were macrophagous predators and/or scavengers.

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti­ tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com­ mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes­ sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in­ terested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

Contrary to common perception, this basin was often not stagnant; evidence of current activity and episodic oxygenation events are characteristic of many units. In fact, lag deposits of detrital pyrite roofed by black shale, erosional runnels, and cross stratified deposits of tractional styliolinid grainstone present a counter intuitive image of episodic, moderate to high energy events within the basin. We will discuss current-generated features observed at field stops in the context of proposed models for their genesis, and we will also examine several key Late Devonian bioevents recorded in the Upper Devonian stratigraphic succession. In particular, two stops will showcase strata associated with key Late Devonian extinction events including the Frasnian-Famennian global crisis.
