FIGURE 9 in Termite nests in eolian backshore settings: An unusual record throughout the Quaternary in the Neotropical realm

FIGURE 9. Features of the casted nests. A. Photomosaic evidencing the hypogean portion of nest D.4; observe that the structure present two main disposition of passages, with concentrated passages very similar to epigeal portion going up to ~70 deep, and elongated passages mostly vertically-oriented with lateral chambers occurring only in deeper part of the structure; horizontally-oriented passages are more common in the middle of the underground portion, with local globous chambers. Dotted lines colored in yellow represent inferred connections, lost during removal of the cast. B. Plan view of the bottom of epigeal portion, with concentrated pattern of passages (central chamber is absent). C. Casted concentrated passages evidencing a random distribution. D. Walls of passages in epigeal portion, showing high concentration of sand lined by organic matter in its interior (this sample was not casted).
