Acarinina africana is an extinct species of planktonic Acarinina belonging to the family Truncorotaloididae.[1] It is a short-lived "excursion taxon" that is highly characteristic of the Paleocene–Eocene Thermal Maximum (PETM), a major global warming event that occurred roughly 56 million years ago.
First described by paleontologist Z.R. El-Naggar in 1966 from specimens found in Egypt, A. africana is distinguished by its axially-compressed shell and a strongly lobulate peripheral margin.[2] Fossils of this species have been found in marine sediments ranging from tropical to temperate regions, including the central Pacific Ocean, the Atlantic coastal plain, and northern Africa.
