Material examined

BRAZIL: Estre outcrop, Rosário do Catete Municipality, Sergipe State (samples MP-1427 and MP- 1429), approximate coordinates 10°41' S, 37°02' W.

Measurements

Hypotype (CP-670): valve: height = 0.51 mm.

Remarks

Despite its unusual fine, nodose ornamentation, Cytherella sp. 1 is comparable in overall shape to several Cytherella species with Albian (partly or not) distribution, which justifies its generic attribution. These include Cytherella ovata ( Roemer, 1841) (several sedimentary units, ages and locations in Europe, and possibly nearby regions in America, Africa and Asia) ( Brown 1957; Herrig 1966; Bassoulet & Damotte 1969; Swain & Brown 1972; Majoran 1989; Witte et al. 1992; El-Nady et al. 2008); Cytherella comanchensis Alexander, 1929 (Fort Worth Formation, United States, upper Albian) ( Alexander 1929); and Cytherella fredericksburgensis Alexander, 1932 (Goodland Formation, United States, Albian) ( Alexander 1932). However, because of the lack of well-preserved specimens in the current samples, it was not possible to provide a more specific identification of them.

Paleoecology and distribution

Cytherella sp. 1 is a marine, outer shelf species occurring in the Taquari Member, Riachuelo Formation, Sergipe-Alagoas Basin, Brazil, upper Albian (earlier than the Reticulocosta edrianae subzone (MSA- 0.4)), Aracajuia benderi zone (MSA-0).
