Dr. Lanny H. Fisk, PhD, PG
Chairman of the Board/Principal Paleontologist

Dr. Fisk has over 25 years experience as a professional geologist/paleontologist and 20 years as a paleontological consultant doing paleontological resource impact assessments and surveys, preparing CEQA and NEPA environmental documents and mitigation measures, managing environmental compliance monitoring programs, and coordinating and consulting with city, county, state, and federal resource agencies to resolve environmental concerns regarding paleontological resources. He has supervised paleontological resource impact mitigation programs requiring monitoring of major earth-moving projects, recovery and collection of fossil remains and fossiliferous rock samples, supervision of field personnel, and preparation of progress and final reports. These projects involved extensive coordination and consultation with project sponsors, other consulting firms, and permitting agencies; adherence to strict delivery schedules; and completion within specified budget limits. He evaluates fossiliferous rock samples to determine the need for microfossil processing, and identifies fossil remains as part of paleontological monitoring and resource recovery programs. Dr. Fisk has done extensive research in paleobotany, palynology, paleornithology, biostratigraphy, and paleoecology of Cretaceous, Tertiary, and Quaternary formations of the western United States, including research in eight national parks and monuments. He has developed laboratory research facilities at two universities for studying fossil floras, processing fossiliferous rock samples to recover plant microfossils, and interpreting age and paleoenvironment. Dr. Fisk has held many roles in various paleo organizations and is currently involved in writing the SVP guidelines.
