John Day Fossil Beds National Monument
ISSUE VIII JANUARY 2007 NARG Newsletter North America Research Group Northwest Fossil Fest Recap Last August NARG held it's first annual Northwest Fossil Fest held at INSIDE THIS ISSUE the Rice Museum in Hillsboro Oregon. The goal of the Fest was to NW Fossil Fest Recap 1 promote, educate, showcase fossils Radiocarbon Dating Fund 3 from the Pacific NW, and to have John Day Fossil Beds fun, all of which was accomplished. National Monument 3 Taxonomy Report #6 5 The tagline for the Fest is “Inspire, Inquire, Interact” and nothing What is “Fossil Search and Rescue? inspires more than displaying some of the amazing fossils specimens that Oregon Fossils have been found in the Pacific NW. Plants of the Jurassic Period 7 Tami Smith making a batch of Trilobite Cookie Many guests where surprised at the Trilobite Morphology 8 wide range of life forms that once lived where we do today. Inquiry minds want to know and we had a top-notch line up of guest speakers such as Dr. Dr. Ellen Morris Bishop, Dr. Jeffrey A. Myers, and Dr. William. N. Orr. This was a great opportunity for guest not only to learn more about the paleontology and geology of Oregon but also to meet 3 of the leading professionals in these fields. More Trilobite Cookie making There were many ways to interact, from the fossil preparation area where demonstrations took place on tools and techniques used to prepare fossils, to fossil identification, and of course all the kids activities that NARG setup. The Screen for Shark Teeth was probably the biggest hits and over 1000 Bone Valley shark teeth where given away. -

The John Day river basin in the north central part of Oregon has been for many years a favorite place for geologic exploration, on account of the occurrence there of vertebrate fossils. In recent years, however, attention has been further directed to this region from time to time by reports of the discovery of coal, oil, gas and other mineral resources. -

Petersen, Graduate Offi Representative The geology of the Castle Rock area aids in the under- standing of Cenozoic volcanic stratigraphy and structures in an area where these volcanic rocks thin near the margins of the pre-Tertiary basement rocks and structural trends are overlapping. The Castle Rock area is unique in several as- pects and is important in understanding and interpreting the geology in adjacent regions which have all been studied, at least on a regional basis. -

Synoptic Taxonomy of Major Fossil Groups
APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)

Stratigraphy and Sedimentary Petrology of the Mascall Formation, Eastern Oregon
AN ABSTRACT OF THE THESIS OF John L. Kuiper for the degree of MASTER OF SCIENCE in GEOLOGY presented on February 12, 1988 . Title: THE STRATIGRAPHY AND SEDIMENTARY PETROLOGY OF THE MASCALL FORMATION EASTERN, OREG17,,, Abstract approved: Redactedfor privacy Dr. Robert D. Lawrence The type section of the Mascall Formation, which islocated in the John Day Valley, is interpreted to represent a sequenceof paleosols. These fossil soils were formed on a floodplainduring the middle Miocene. The measured thickness of this section is 1340feet, and although the top of the section is truncated by anerosion surface, the original thickness was probably not much morethan 2000 feet. Sediment accumulation rates were high in thevicinity of the type section with deposits being predominantly ofthe overbank type. Minimum sediment accumulation time at the typesection is thought to have been several hundred thousand years. A concretionary horizon, which occurs within the typesection is determined to represent a significant temporal hiatus. Because of the absence of caliche in this layer and elsewhere in the typesection, and because of the occurrence of moisture-lovingplants, a wet, temperate climate is envisioned for the typesection during the middle Miocene (Barstovian). The floodplain sediments of the type section arepredominantly composed of ash which was produced by nearbysilicic volcanism. This ash was mostly washed in from thesurrounding highlands, but on occasion the floodplain was blanketed by air falldebris. Scanning electron microscopy demonstrates that this ashis of the type erupted by plinian and pelean type volcanoes. The ash has been mostly altered to clay minerals, and SEM, TEM, and XRDanalyses, show these clays to consist principally of smectite (Ca, Mg), with lesser amountsof kaolin and tubular halloysite. -
