Christian Klug et al. have re-examined the Early Carboniferous coleoid Gordoniconus beargulchensis by Reflectance Transformation Imaging, various lights and synchrotron revealing new anatomical details. They discuss evolutionary scenarios of how conchs became internalized, as well as the timing of other important steps in early coleoid evolutionary.
