Roadway construction projects (both new construction and improvements to existing roadways) result in large-scale excavations. In many cases the excavations temporarily expose ancient sedimentary rock units and their contained paleontological resources. Because of the linear nature of roadway construction, the excavations often provide a broader view of the geological and paleontological record of an area. The linear nature of such projects also involves challenging construction situations, which PaleoServices staff have developed the know-how to work with.
As a measure of this experience, PaleoServices has provided paleontological consulting services to Caltrans (District 11) on an on-call basis since 1991.
