Fig. 7T

Material examined

BRAZIL: Porto dos Barcos 3 outcrop, Riachuelo Municipality, Sergipe State (sample MP-1470), approximate coordinates 10°43' S, 37°10' W.

Measurements

Hypotype (CP-714): left valve: length = 0.41 mm, height = 0.24 mm.

Remarks

Microceratina ? sp. 1 vaguely resembles other species of Microceratina in Colin et al. (2005) in general shape (which is incomplete in the present specimen). Its ornamentation, however, bears no resemblance to any of the aforementioned, and for this reason it is only tentatively placed in this genus.
