Benedetti, A, 2017, Eocene / Oligocene deep-water agglutinated foraminifers (DWAF) assemblages from the Madonie Mountains (Sicily, Southern Italy), Palaeontologia Electronica 20 (1), pp. 1-66 : 41

Ammobaculites sp. 3

Figure 19.13

Material. One specimen from the sample PC15.

Description. Test free, large, initially planispirally involute coiled with 4 chambers divided by depressed sutures in the last whorl. The unique preserved chamber of the uniseriate stage is very large, and has a rectangular section. Wall thick, coarsely agglutinated.

Remarks. Differs from A. agglutinans ( d’Orbigny, 1846) by the larger size, and by the shape of the ultimate preserved chamber. Ammobaculites sp. 1 has more chambers and sutures less depressed.
