BU'l'TE NATIONAL MONUMENT PROPOSAL: That Fossil Butte and surroUlld.ing lands and features in W;yOIIIing be established as the Fossil Butte f!ationnl ~!onument e.nd be administered by the National Park Service. !OOATIC»!: Fossil Butte is about 10 miles vest oi' Kemme1•er: Lincolll County • Wy€nning9 adjacen'~ to U, S, 30N-~an au-weather • t:rans­ contineutal higl:lway. DESCRIPTION OF AREA: The proposed monument includes Fossil Butte, a rugged topograPhic feature rising 1:000 feet above the valley floor to au elevation of' over "? ,500 feet, This butte and the associated Ccndick Ridge a:re made up of the 1-/asatch and Green River formations which contain numerous, well-preserved fossils of Eocene age. Fl•om vantage poiuts on the ridge interesting features associated with the geolosic history of '~hese formations and the al1oient inland lake in which the Green River formatiou was deposited can be observed, S:WNIF:ICf..NCE .MID NEED FOR CO.I'ISERVM:!OH: Foosil Butte, from the scientific viewpoint, is of national significance because of its unusual eoncentration of aquatic vertebrate remains. Knovn loca­ tions of fossil f'ieh of any age are rare, but here thousands of :fish f'ossil.G a:ra pre:;ent IW.d fossils :from th;i.s locality are exhibited in museums througllcnrt. the world. These fosGils represent the evolu~ tion and modernization o:~ fresh~va:'Ge-.<" fishes better tltan these from arJiY' other kn01m site iu the world. The fossil remains o:f plant a.nd animal life in the Wasatch forllllltion are of added value along with the outstanding geologit; CX81l\Ples of lake, shoreline, and tl•ibutary river ;f'l.ocid plain deposit>~. SUI'l'ABII..ITY: This area is highly suited f'or preservation and development as a national l!'.oilUlllent. It has great scientific interest for the geologiat, paleontoloeiat, icthyologist and botanist as well as for the visitor who bas seen i'oss:l.l fishes from this local·· 1ty exhibited iu museums elsevhereo The area is relatively free from mamnade iutrusions with no devel.oped properites included within the proposaL It is readily access:l.ble :from an all... weather road. FEASIBILI'l'lr: Oi' the 8,2110 acres inclw.ed in the proposal, 86 percent is already in Federal owrwrsbip0 9 percent is ·State~01med land and 5 :percent is priv~tel;y <T.rned. The area con'roins all undeveloped graz., ing land~-r.rostly UDder lelllle to sra.zing allotteea. 'l'bere is a good possibility for exchenglZlg the private al!d State-owned lands for Federal lands outside 'Ghe boull'dary, !:1' these exchanses could be made, no Federal f'1.md.s for land acqu!sition would be required a.nd no private lands would be removed f1•om the tax rolls. PROPOSED DEVELOPl4ElWJ.' AND USE: A visitor eerrter· containing edil!inistra·t;ive offices and a l!l.l.tSeuJil would be located near u.s. 30N as an initial i:n:fOl'mation center and contac·c point for visitors to the na'cional F.!Ollument.

The rising educational I level of our citizens has lead to a widespread interest in this, the field of paleontology. Although fossils have long been of fundamental scientific importance and traditionally displayed in public and institutional museums, I their exhibition and interpretation in-place as a cultural and educational medium has only recently come to public attention. A notable example is I the quarry development at Dinosaur National Monument. The phenomenal increase in visitors at the Dinosaur Quarry since com­ pletion of the visitor center there in 1959, is a strong indication of this Nation•s endorsement of the preservation and interpretation of our rich I paleontological heritage. The success of the Dinosaur development and the ever-increasing threat of exploitation or destruction of other well-known fossil beds sharply point out the desirability of preserving some of them, I both for scientific study and for public enjoyment. A goal of the National Park Service is to include within the National I Park System a representation of the more significant chapters of the his­ tory of life as revealed by fossil remains. Some are already represented in existing parks. For example, the earliest known form. of life, exempli­ fied by fossil algae of Precambrian age, is represented at Glacier National I Park; fossil remains of many invert~brates are found in the sedimentary rocks of several parks and monuments, but especially at Grand Canyon; a form of plantlife is represented by the petrified. forests of Yellowstone I and Petrified Forest National Parks; and an important chapter in the Age of Reptiles is represented at Dinosaur National Monument. I Lacking representation in the National Park System is the fossil story of the modernization of fresh-water fishes. This void can be filled by the establishment of a national monument at the site described in this report. Here is an opportunity to present for the benefit of all people another I chapter in the geologic history of life. I I I I I I I I I I I I I I I I I Fossil Butte I I I I I I I I I INTRODUCTION I Fossil Butte, world famous for its well-preserved fossil fishes, is I located about 10 miles west of Kemmerer, Lincoln County,' Wyoming. Fossils have been collected at this locality for almost a century, and specimens I from this site are exhibited in museums throughout the world. A reconnaissance study of this area was made by the National Park I Service early in 1959, followed by more detailed studies in subsequent years~ The results of these investigations are covered in this report. I Studies such as this are part of the long-range effort of the National I Park Service to identify areas of sufficient importance to be included in the National Park System. The eventual objective of these efforts is a I system of national parks that will represent the most outstanding examples of America's natural and cultural heritage. I In September 1961, the Advisory Board on National Parks, Historic I Sites, Buildings and Monuments recommended to the Secretary of the Interior, establishment of the Fossil Butte area as a national monument. I The purpose of this report is to present sufficient information about the Fossil Butte site so that its significance to the Nation is understood I at the local, state, and national levels, and to describe what the National I Park Service believes should be done to preserve and interpret it for the benefit and enjoyment of the people. I I I 1 I I I I I I I I I I A narrow ridge of badlands connects Fossil Butte with I Cundick Ridge.

  • Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field
    Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field June 12, 2007 ABSTRACT This is compilation of a technical analysis of existing paleontological data and a limited, selective paleontological field survey of the geologic bedrock formations that will be impacted on Federal lands by construction associated with energy development in the Jonah Field, Sublette County, Wyoming. The field survey was done on approximately 20% of the field, primarily where good bedrock was exposed or where there were existing, debris piles from recent construction. Some potentially rich areas were inaccessible due to biological restrictions. Heavily vegetated areas were not examined. All locality data are compiled in the separate confidential appendix D. Uinta Paleontological Associates Inc. was contracted to do this work through EnCana Oil & Gas Inc. In addition BP and Ultra Resources are partners in this project as they also have holdings in the Jonah Field. For this project, we reviewed a variety of geologic maps for the area (approximately 47 sections); none of maps have a scale better than 1:100,000. The Wyoming 1:500,000 geology map (Love and Christiansen, 1985) reveals two Eocene geologic formations with four members mapped within or near the Jonah Field (Wasatch – Alkali Creek and Main Body; Green River – Laney and Wilkins Peak members). In addition, Winterfeld’s 1997 paleontology report for the proposed Jonah Field II Project was reviewed carefully. After considerable review of the literature and museum data, it became obvious that the portion of the mapped Alkali Creek Member in the Jonah Field is probably misinterpreted.

  • The Lost World of Fossil Lake
    Snapshots from Deep Time THE LOST WORLD of FOSSIL LAKE lance grande With photography by Lance Grande and John Weinstein The University of Chicago Press | Chicago and London Ray-Finned Fishes ( Superclass Actinopterygii) The vast majority of fossils that have been mined from the FBM over the last century and a half have been fossil ray-finned fishes, or actinopterygians. Literally millions of complete fossil ray-finned fish skeletons have been excavated from the FBM, the majority of which have been recovered in the last 30 years because of a post- 1970s boom in the number of commercial fossil operations. Almost all vertebrate fossils in the FBM are actinopterygian fishes, with perhaps 1 out of 2,500 being a stingray and 1 out of every 5,000 to 10,000 being a tetrapod. Some actinopterygian groups are still poorly understood be- cause of their great diversity. One such group is the spiny-rayed suborder Percoidei with over 3,200 living species (including perch, bass, sunfishes, and thousands of other species with pointed spines in their fins). Until the living percoid species are better known, ac- curate classification of the FBM percoids (†Mioplosus, †Priscacara, †Hypsiprisca, and undescribed percoid genera) will be unsatisfac- tory. 107 Length measurements given here for actinopterygians were made from the tip of the snout to the very end of the tail fin (= total length). The FBM actinop- terygian fishes presented below are as follows: Paddlefishes (Order Acipenseriformes, Family Polyodontidae) Paddlefishes are relatively rare in the FBM, represented by the species †Cros- sopholis magnicaudatus (fig. 48). †Crossopholis has a very long snout region, or “paddle.” Living paddlefishes are sometimes called “spoonbills,” “spoonies,” or even “spoonbill catfish.” The last of those common names is misleading because paddlefishes are not closely related to catfishes and are instead close relatives of sturgeons.

These plants, invertebrates, vertebrates, ichnotaxa, and microfossils represent a diverse collection of organisms in terms of taxonomy, geologic time, and geographic distribution. In terms of the history of American paleontology, the type specimens found within NPS-managed lands, both historically and contemporary, reflect the birth and growth of the science of paleontology in the United States, with many eminent paleontologists among the contributors. Name-bearing type specimens, whether recovered before or after the establishment of a given park, are a notable component of paleontological resources and their documentation is a critical part of the NPS strategy for their management. In this article, name-bearing type specimens of fossil taxa are documented in association with at least 71 NPS administered areas and one former monument, now abolished.
