Bairdoppilata
sp. 1
Fig. 5M
Material examined
BRAZIL
: Massapê outcrop, Riachuelo Municipality,
Sergipe State
(samples MP-1516, MP-1518, MP- 1520, MP-1545 and MP-1546), approximate coordinates
10°06' S
,
37°10' W
.
Measurements
Hypotype (CP-678): right valve: length =
0.69 mm
, height =
0.32 mm
.
Remarks
Bairdoppilata
sp. 1 is remarkable among
Bairdoppilata
species of the lower Cretaceous because of the combination of the following features: an elongate overall shape, elongate posterior end, comparable to
B. southerhamensis
Weaver, 1982
(although this species' carapace displays greater height) (
Weaver 1982
), and punctuate ornamentation. The current specimens probably represent a new species, but due to the small amount of material (composed solely of valves) recovered, we opt to leave it in open nomenclature.
Paleoecology and distribution
Bairdoppilata
sp. 1 is a marine, shelf species occurring in the Maruim Member, Riachuelo Formation, Sergipe-Alagoas Basin,
Brazil
, Albian,
Aracajuia antiqua
zone (MSA-1).
