  1. Buried alive

    Snapshot Title: Buried alive
    Taken by: Callan Bentley

    Image: Calvert Formation, Scientists' Cliffs, Maryland (#8 of 8)
    Image Owner: Callan Bentley



    Description:

    The articulation of these valves suggests that this clam was buried whole, and didn't have a chance to rot or have its valves (shells) disarticulated before burial. Maybe it was even buried alive!



  2. Outcrop face

    Snapshot Title: Outcrop face
    Taken by: Callan Bentley

    Image: Calvert Formation, Scientist Cliffs, Maryland (#5 of 8)
    Image Owner: Callan Bentley



    Description:

    Orientation of the exposure face is 334°, 58° (right hand rule).



  3. Worm burrow

    Snapshot Title: Worm burrow

    Image Owner: Callan Bentley



    Description:

    Filled with lighter-colored sediment. Oblique cross-section.
