The new foraminiferal genus Ammogloborotaloides n. gen. and subfamily Ammogloborotaloidinae n. subfam. from the Neogene of Venezuela: an example of isomorphism between agglutinated and planktonic Foraminifera

We report the occurrence of two new species of the new agglutinated foraminiferal genus Ammogloborotaloides in the Miocene of western Venezuela. These two taxa have been assigned informal names and have been known to the petroleum industry in Venezuela for many years, but have never been described....

Description
Summary:We report the occurrence of two new species of the new agglutinated foraminiferal genus Ammogloborotaloides in the Miocene of western Venezuela. These two taxa have been assigned informal names and have been known to the petroleum industry in Venezuela for many years, but have never been described. A . truncatulinoidiformis n. sp. is the type species and the second species, A . sp. 16, is left in open nomenclature. The two species of Ammogloborotaloides are strongly isomorphic with the planktonic foraminiferal species Globorotalia truncatulinoides and Globorotalia crassaformis , and illustrate the possible evolutionary connections between agglutinated benthics and the planktonic foraminifera.
