Springtime along the Mid-Atlantic seaboard thousands of horseshoe crabs spawn on beaches under the glow of the full moon; a reoccurring ritual for the last 450 million years. Citizen scientists venture out along the shore to keep tally of their population. The film attempts to document the annual observance on 16mm film exposed in timelapse with ambient moonlight. LIVING FOSSIL is just a brief glimpse into this prehistoric phenomenon.
