Organisms interact with their
environment, and in many cases, they leave geological evidence. Seventy years ago, Emery noted and described amphipod burrows (sand fleas) in
California beaches. He went on to
suggest that the presence of comparable burrows in ancient successions “should be supplementary indications of a
marine beach environment because they require a temporary drying of the beach
such as occurs between tides.” Hmmm. As we end the summer beach season in
the northern hemisphere, JSR PaperClips readers who visit the beach and are hassled
by sand fleas may want to take this paper along to consider the geological
significance of the things that annoy them.
