Fig. 6T

New material examined

BRAZIL: Porto dos Barcos 3 outcrop, Riachuelo Municipality, Sergipe State (sample MP-1468).

Measurements

Hypotype (CP-694): right valve: length = 0.55 mm, height = 0.24 mm.

Remarks

The only specimen of Patellacythere sp. 1 found in the present samples resembles those of P. parva Weaver, 1982 , although not the ones in Witte (1992), which are incomplete, having lost most of their posterior ends. However, Patellacythere sp. 1 has a slightly less developed lateral u-shaped swelling, and therefore is dubiously placed in the current species.

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