Caption:
Under a magnification of 1202X, this 2005 scanning electron microscopic (SEM) image depicted the morphologic characteristics of the inner surface of an unidentified bird’s eggshell. In this view, the details revealed included the surfaces of the mammillary cones, and a number of intermammillary pores, i.e., canals that span the distance between the shell’s outer cuticle layer, and the interior membranous layers. It is through these pores that the diffusion of gasses takes place. This shell fragment was retrieved from the grounds of the Decatur, Georgia suburbs.
