• Resumen

  • This paper presents Truncorotaloides libyaensis as a new species of the stratigraphically important genus Truncorotaloides Bronnimann & Bermúdez from the Middle Eocene Apollonia Formation of the northern coastal escarpment of Jabal al Akhdar, south of Al Hilal village. It was possible to follow the morphologic development of Truncorotaloides rohri, T. libyaensis, and T. haynesi from T. topilensis, which is considered here to be the ancestral form of the genus.
