Description	Recurvoides infernus sp. nov., one of the oldest representatives of the superfamily Recurvoidacea (Foraminiferida), is described in a thin black claystone overlaying the manganese deposits of the Krížna Unit in the Tatra Mountains (Poland). These manganese carbonates/silicates were laid down around a shallow exhalative submarine vent, active in the Early Toarcian. The microfossils are possibly the first described Jurassic foraminifera associated with hydrothermal vents. The assemblage is dominated by a high abundance and dominance of this new species. The primary lamination of the claystone, the lack of any macrofauna, and an elevated TOC content point to oxygen-deficient conditions during sedimentation of these deposits. The nearly exclusive occurrence of agglutinated foraminifers suggests a low pH level. It is likely that foraminifers colonized vent-related bacterial mats that acted as a rich and stable food source. Modern shallow- and deep-water hydrothermal vents may represent similar habitats.
