In support of the National Park Service’s first ever Fossil Day event, the NPS and the Natural History Museum of Los Angeles County asked Envicom to be a presenter at the Santa Monica Mountains National Recreation Area visitor center. Envicom presented information from their LAUSD San Pedro High School discovery of several Late Miocene marine bonebeds with millions of fish, shark, sea turtle, and shore bird bones, as well as thousands of coprolites (fossil animal feces). School children and their parents were able to participate in cleaning the coprolites and looking at what they contain under a digital microscope. Hundreds of small fish and invertebrate bones are in the coprolites, eaten by dolphins, sharks, and other marine animals 9-million years ago, including by megalodon sharks, the largest sharks that ever existed!
