The identified ostracod
species Conchoprimitia social, Protallinnella grewingkii, Aulacopsis simplex and Unisulcopleura punctosulcata from the limestones below and above the Volkhov Oil Collector in the Vergale-50 core section are common for upper Dapingian and lower Darriwilian strata in Latvia and southern Estonia (Tinn et al.
The Khadum Formation is subdivided by its lithological parameters into three subformations: the lower Pshekh subformation, the middle Polbin or ostracod
subformation and the upper Morozkin ravine subformation.
They go with males who've focused on sperm transfer efficiency, developing a strong "pumping mechanism" in their proportionally oversized ostracod
But thanks to thousands of ostracod
species still alive today, it is well documented how male shells differ from those of the females they seek to woo.
From these, 12 taxa were identified, four of Cladocera, three of Copepoda, four of Rotifera and the larvae of Chaoborus (Table 1), however total diversity is higher since other groups such as an Ostracod
and another Diptera larvae were observed but it was not possible to identify them due to their low abundance.
Previously the age of this succession had been regarded as wholly Early Devonian (Lochkovian or Pragian), based principally on an undescribed ostracod
, which Berdan (1990) considered to belong to a quadrilobate beyrichiacean form allied to Cornikloedenina; but it is more like Carinokloedenia from the Pragian of Podolia and the Lochkovian of northern France.

Scientists from Europe, the US, and Asia discuss freshwater and marine ostracod
genera/species and the ostracod
family Entocytherids, including revisions of genera, descriptions of new species, and new studies on biogeography, ecology, and morphology.
The creature-related to crabs, lobsters and shrimp-is an ostracod
, or a type of crustacean sometimes known as seed shrimp.
