Paleo Solutions, Inc. (Paleo Solutions) updated the PRMP (this document) with the results of additional record searches and field work completed since the 2013 report. The PRMP was prepared based on the results of extensive geologic map reviews, literature searches, and museum record searches; and the results of paleontological field surveys that were completed for the Keystone XL Pipeline Project (Project) between 2008 and 2018. Paleontological monitoring locations recommended in this PRMP are based on the March 4, 2019 geographic information system (GIS) dataset provided by exp Energy Services. Across its centerline length of approximately 285.36 miles (Figure 1), the Montana portion of the Project traverses 20 geologic units (4 members of the Fort Union Formation are combined in Table 2) ranging in age from Cretaceous to Holocene. Fossiliferous geologic units include a wide variety of terrestrial and marine sedimentary rocks and surficial sedimentary deposits that range from Cretaceous to Pleistocene in age. The purpose of pre-construction paleontological field surveys is to inspect areas with exposures of paleontologically sensitive bedrock or surficial sediments, including previously recorded fossil localities, for the presence of scientifically important fossils. Paleontological surveys are unnecessary in areas with no surficial exposures of fossiliferous bedrock. The purpose of construction monitoring is to locate, identify, and remove from the path of construction, any scientifically important fossils unearthed by excavation equipment before they are irreparably damaged. Paleontological monitoring is unnecessary unless the location and depth of disturbance will impact fossiliferous bedrock. In compliance with MDEQ (2011) requirements,

  • Plant Macrofossil Evidence for an Early Onset of the Holocene Summer Thermal Maximum in Northernmost Europe
    ARTICLE Received 19 Aug 2014 | Accepted 27 Feb 2015 | Published 10 Apr 2015 DOI: 10.1038/ncomms7809 OPEN Plant macrofossil evidence for an early onset of the Holocene summer thermal maximum in northernmost Europe M. Va¨liranta1, J.S. Salonen2, M. Heikkila¨1, L. Amon3, K. Helmens4, A. Klimaschewski5, P. Kuhry4, S. Kultti2, A. Poska3,6, S. Shala4, S. Veski3 & H.H. Birks7 Holocene summer temperature reconstructions from northern Europe based on sedimentary pollen records suggest an onset of peak summer warmth around 9,000 years ago. However, pollen-based temperature reconstructions are largely driven by changes in the proportions of tree taxa, and thus the early-Holocene warming signal may be delayed due to the geographical disequilibrium between climate and tree populations. Here we show that quantitative summer-temperature estimates in northern Europe based on macrofossils of aquatic plants are in many cases ca.2°C warmer in the early Holocene (11,700–7,500 years ago) than reconstructions based on pollen data. When the lag in potential tree establishment becomes imperceptible in the mid-Holocene (7,500 years ago), the reconstructed temperatures converge at all study sites. We demonstrate that aquatic plant macrofossil records can provide additional and informative insights into early-Holocene temperature evolution in northernmost Europe and suggest further validation of early post-glacial climate development based on multi-proxy data syntheses. 1 Department of Environmental Sciences, ECRU, University of Helsinki, P.O.

  • Standard Procedures for the Assessment and Mitigation of Adverse Impacts to Paleontological Resources
    Standard Procedures for the Assessment and Mitigation of Adverse Impacts to Paleontological Resources Society of Vertebrate Paleontology Impact Mitigation Guidelines Revision Committee Abstract Fossils are nonrenewable paleontological resources that are subject to impacts from land development. Procedures are presented for evaluating the potential for impacts of a proposed action on paleontological resources and for mitigating those impacts. Impact mitigation includes pre-project survey and salvage, monitoring and screen washing during excavation to salvage fossils, conservation and inventory, and final reports and specimen curation. The objective of these procedures is to offer standard methods for assessing potential impacts to fossils and mitigating these impacts. Introduction Fossils are nonrenewable paleontological resources that are afforded protection by federal, state, and local environmental laws and regulations. The Paleontological Resources Preservation Act (PRPA) of 2009 calls for uniform policies and standards that apply to fossils on all federal public lands. All federal land management agencies are required to develop regulations that satisfy the stipulations of the PRPA. Section 6302 of the PRPA mandates that federal agencies "shall manage and protect paleontological resources on Federal land using scientific principles and expertise." Thus, federal agencies need the help of the professional paleontological community in the formulation and implementation of these PRPA- mandated policies and regulations. The potential for destruction or degradation of paleontological resources on both public and private lands selected for development under the jurisdiction of various governmental planning agencies is recognized. The standard procedures below are intended to be applicable to both private and public lands under the jurisdiction of local, city, county, regional, state, and federal agencies.

Introduction and Summary: The Paleontological Heritage of Grand Canyon National Park By Vincent L. Santucci1 1National Park Service Geologic Resources Division 1849 “C” Street, NW Washington, D.C. 20240 Throughout my life I have been bestowed the privilege of experiencing the world-renowned landscape and resources of the Grand Canyon from many perspectives and viewsheds (Figure 1-1). My first views were standing and taking photos from the many vantage points and overlooks along the North and South rims. I have enjoyed many hikes into the canyon with colleagues from the National Park Service (NPS) or with academic geologists and paleontologists. On a few occasions I ventured down and then back up the trails of the canyon with my children Sarah, Bethany, Luke, Jacob, Brianna and Abigail, often carrying one or more in my arms on the climb against gravity. I traversed by foot to the base of the canyon at Phantom Ranch and gained a greater appreciation for the geologic story preserved in the park strata. I have gazed intensely out the window of many commercial aircraft from above this geologic wonder of Earth, contemplating the geomorphic “grandeur” created over "Deep Time" and the artistry of processes perfected by “Mother Nature.” I pinch myself when I recall the opportunity when my friend Justin Tweet and I were granted permission to fly into the western portion of the Grand Canyon on a small NPS plane operated by a pilot from Lake Mead National Recreation Area.

  • Geologic, Climatic, and Vegetation History of California
    GEOLOGIC, CLIMATIC, AND VEGETATION HISTORY OF CALIFORNIA Constance I. Millar I ntroduction The dawning of the “Anthropocene,” the era of human-induced climate change, exposes what paleoscientists have documented for decades: earth’s environment—land, sea, air, and the organisms that inhabit these—is in a state of continual flux. Change is part of global reality, as is the relatively new and disruptive role humans superimpose on environmental and climatic flux. Historic dynamism is central to understanding how plant lineages exist in the present—their journey through time illuminates plant ecology and diversity, niche preferences, range distributions, and life-history characteristics, and is essential grounding for successful conservation planning. The editors of the current Manual recognize that the geologic, climatic, and vegetation history of California belong together as a single story, reflecting their interweaving nature. Advances in the sci- ences of geology, climatology, and paleobotany have shaken earlier interpretations of earth’s history and promoted integrated understanding of the origins of land, climate, and biota of western North America. In unraveling mysteries about the “what, where, and when” of California history, the respec- tive sciences have also clarified the “how” of processes responsible for geologic, climatic, and vegeta- tion change. This narrative of California’s prehistory emphasizes process and scale while also portraying pic- tures of the past. The goal is to foster a deeper understanding of landscape dynamics of California that will help toward preparing for changes coming in the future. This in turn will inform meaningful and effective conservation decisions to protect the remarkable diversity of rock, sky, and life that is our California heritage.

Using four sieve layers for each interval (1 millimeter, 500 by hand (Birks 2001). They are often studied in conjunction with pollen studies micron, 250 micron, 125 micron), the samples were washed with low-purity DI because they help provide more conclusive look at the local record of vegetation, water. The remains from the top two screens – 1 millimeter and 500 micron – owing to their shorter dispersal range.
