Uinta Paleontological Associates, Inc. was established in 1992 as the parent organization for paleontological research and consulting performed by Company President Sue Ann Bilbey, Ph.D., Geologist and Paleontologist and Vice-President and Director of Field Operations Evan Hall. Their primary interests are paleontology, sedimentology, and stratigraphy of the nonmarine rocks of the Western Interior of the United States. In addition, professional affiliates (subcontractors) have assisted in paleontological resource evaluation in Colorado, Nevada, Oregon, Washington, and Idaho. Uinta Paleo is forming a substantive paleontological database for resource evaluation and protection, as well as educational and interpretive aids for these regions. In the field, we are well known for keeping the projects on line with as few delays as possible.  Uinta Paleo has been affiliated with industry, academia, and museums as well as the consulting community. Due to that familiarity, we work closely with the people involved to quickly produce professional documents, reports, and paleontological evaluations for projects.

Geologist and Paleontologist

Dr. Sue Ann Bilbey is a geologist and paleontologist with over 18 years experience managing environmental impact assessments. She has assisted a variety of firms in compliance procedures for Federal Energy Regulation Commission (FERC), applications regarding paleontological resources as well as federal and state requirements for protection of paleontological resources (1906 Federal Antiquities Act, Historical Sites Act of 1935, National Environmental Policy Act of 1969 (NEPA), the Federal Land Policy and Management Act of 1976), and BLM Paleontology Resources Management Manual and Handbook H-8270-1 (revised 1998 - currently under revision 2007).

Her technical capabilities include field delineation of paleontologically sensitive formations and identification of significant vertebrate, invertebrate, and plant fossil localities, preparation of technical analyses of existing paleontological data, field surveys, paleontological sensitivity reports, design of monitoring and mitigation plans, and supervision of paleontological monitors during construction, and supervision of post-construction preparation and curation of fossil materials. She has been the project manager (Chief Paleontologist) on six large FERC or interstate projects: Entrega/REX Gas Pipeline Project, Mid-America Rocky Mountain Expansion Pipeline, Northwest Pipeline Corporation Expansion I and II Projects, the NWP Dinosaur/ Dragon Trail Replacement Project, and Questar Corporation's Fidlar Station to Clay Basin Project. In addition she has done an acreage review of fossil resources for Dinosaur National Monument and the National Park Service, a Colorado Interstate Gas Pipeline in Wyoming, Yankee Gulch American Soda Pipeline in Piceance Creek, CO, a buried powerline project for Utah Power and Light, roads for Colorado and Utah Departments of Transportation as well as numerous oil/gas well-site  and small pipeline evaluations in Utah, Colorado, and Wyoming.

She is the President and principal investigator for Uinta Paleontological Associates. She currently holds BLM antiquities permits as applied to paleontology in Colorado and Wyoming.  In addition to holding a Ph.D. in Geology from the University of Utah, she is certified as a Utah Professional Geologist (5535071-2250). 

She has coordinated many of these consulting and research projects with other professionals and keeps the academic community well advised of her activities. She has presented her resource management plan for paleontological resources as applied to construction impacts on federal lands to the National Park Service/Bureau of Land Management Partners and Paleontology meetings.  The paleontological results from the NWP Expansion II project were presented at the Western Association of Vertebrate Paleontologists meeting in Hagerman, Idaho.  In addition, she has authored or co-authored numerous professional papers that have resulted from her consulting and other professional geological and paleontological work.


Evan Hall is Vice President of Uinta Paleontological Associates Inc. and "the FINDER." Evan's artistic eye has aided the Uinta Paleo since 1992, providing excellence in photographic as well as graphic presentations in reports, posters, and professional paleontological publications. His paleontological talents include field identification of fossils (osteological as well as biological), collection (including quarry mapping and fossil stabilization), and laboratory preparation of vertebrate, invertebrate, plant and ichnofossils. He has co-authored many professional paleontological articles as well as consulting reports with Dr. Bilbey (his wife). 

Within the professional paleontology community, he has contributed significant time and money to numerous volunteer efforts - President and Vice President of the Uinta Basin Chapter of the Utah Friends of Paleontology as well as statewide President in 2003-4. He also participated in a Utah Museums Association grant for the research and graphic presentation of the Utah Field House display - Vertebrate Paleontology in Utah - 150 years of Discovery.

To his credit, Evan has discovered several paleontologically significant fossils:
  • First Pliosaur found in Utah - 1990
  • Oldest aromatic cedar in North America - 1995
  • Oldest true Ankylosaur in North America - 1996 (which was named for him and Bilbey - Cedarpelta bilbeyhallorum)
  • Nearly complete Haplocanthosaurid Sauropod dinosaur skeleton. Uinta Paleo is preparing a professional monograph on this discovery. It is the first definitive occurrence of this genus in Utah. Research is continuing with comparisons being made to a large number of sauropod dinosaurs throughout the USA and Great Britain.
  • Reidentification of Earl Douglass' Dolichorhinus and Skull Pass Quarries, and Uinta Basin Well #2
