Excavation continues at the site of a nine-million-year-old marine bone bed beneath Los Angeles Unified School District’s San Pedro High School. Our paleontology team recently uncovered a collection of gastroliths, the water-worn stomach stones used by sea turtles for digestion and buoyancy, likely deposited near what was once an offshore island off the California coast.

Analysis is now underway to determine whether these ancient turtles selected stones based on size, shape, or color. This ongoing project is led by Wayne Bischoff, Envicom’s Director of Cultural Resources.

As cultural monitoring continues, Envicom remains committed to keeping projects moving forward while protecting what lies beneath.
