Notes on the Foraminiferal Genera Laterostomella De Klasz and Rérat and Streptochilus Brönnimann and Resig
the biserial foraminiferal genera Laterostomella de Klasz & Rérat (1962) and Streptochilus Brönnimann & Resig (1971) have been described from the Miocene of Gabon and from Miocene to Recent levels of the Pacific and Indian Oceans, respectively. Both genera have since been found in the Upper...
