A major strength of the fossil collections acquired from museum paleontologist Greg Retallack is the precise geological and locality data that accompanies each specimen. The most important piece of scientific information on a fossil is its exact location, because this enables detailed scientific work on such questions as paleoenvironmental change and rates of evolution. Fossils from Oregon, acquired largely on student field trips over the past three decades, have been collected within a modern geological framework and with benefit of accurate topographic maps and GPS technology.
