The shelly debris in these specimens came from sessile epi- and in-faunal organisms (mainly pelecypods
and brachiopods but also encrusting algae or bacteria) that lived in the region and that are highly negative with respect to [sup.13]C.
The fauna of the lagoonal muds of Agoulenitsa Lagoon are mainly brackish, characterized by the edible pelecypod
Functional morphology and palaeontological significance of the conchiolin layers in corbulid pelecypods
. Lethaia 12:341-351.
(5) Twenty-five meters of gray, thick-bedded limestone including many pelecypod
Invasion and extinction: The last three million years of North Sea Pelecypod
One month after water diversion, total macroinvertebrate, chironomid, ceratopogonid and pelecypod
densities were still significantly reduced relative to the reference site (pre- post2 diversion contrasts), and remained so 2 mo after diversion (pre- post3 diversion contrasts).
Observations on the sperm of the pelecypod
Anodontoides ferussacianus (Lea).
The recognizable skeletal allochem include; echinoderms, brachiopods, gastropods, pelecypod
, dasycladacean algae and bioclasts.
Orientation of empty pelecypod
shells and shell fragments in quiet water.
The Biostratigraphic study of pelecypod
and gastropod fauna of Eocene in Thano Bula Khan have prominent position in biostratigraphy of Sindh.
