Ponceammina Vancouveringi, N. Gen., N. Sp., (Ponceamminidae, Foraminiferida) From the Early Miocene of Puerto Rico

Abstract

The new agglutinated foraminiferid genus Ponceammina (type species: P. vancouveringi) is characterized by an asymmetrical planispiral to low trochospiral test, which may exhibit unequally inflated uncoiling chambers with a terminal slit-like aperture. The new taxon has been retrieved from southwestern Puerto Rico upper bathyal, Early Miocene strata.
