Theodore J. Fremd
Paleontologist/NPS Science Advisor

Each science advisor performs specific roles and functions to support the goal of bringing science and scholarship to PWR parks, the Regional Directorate, and to the National Park Service. The information below is intended to highlight areas of expertise, current activities, and capacities of individual PWR Science Advisors.

Disciplinary and/or geographic expertise:

Vertebrate paleontology, biostratigraphy, taphonomy, paleoecology, curation of natural history specimens, and management of paleontological specimens.
Science liaison capacity:

Faculty member, University of Oregon, Department of Geological Sciences, Eugene, OR

Paleontological research coordinator; interagency agreements with U. S. Bureau of Land Management (four districts), U. S. Forest Service (three National Forests in Oregon and Washington), U. S. Fish and Wildlife Service, Oregon State Parks, The Confederated Tribes of the Warm Springs, The Natural Conservancy, Oregon Museum of Science and Industry, varied private lands with significant fossil resources.


Society of Vertebrate Paleontology (Government Laiason Committee), AAAS, Geological Society of America, Paleontological Society, etc.


NPS Natural History Collections ad hoc committee; Chair, NPS Collections Significance Group (Paleontology), NPS Museum Management Program Council, PWR GIS Committee


World Heritage Assessment, Ipolytarnoc National Park, Hungary

Science needs identification and assessment:

Paleontological resource conservation on public lands
Curation, laboratory, and fieldwork methods with fossilized biotas
Phylogenetic systematics and evolutionary paleoecology
Synthetic focus:
Applicability of “deep time” perspectives to modern ecological syntheses; defragmentation of spatially broad (basin-scale) Tertiary paleontological deposits and their entombed biotas
Strategic resource management approaches:

Relevance of evolutionary paleoecology in conservation of recent biotas; preservation and curation of paleontological resources.
Recent activities include: Paleontological Survey, Wrangell-St. Elias National Park, Alaska; team member of Petrified Forest Paleontological Resource Planning, etc.
