Thaumatocyprididae
''Thaumatocyprididae'' is a family of ostracods in the order Halocyprida The Halocyprida is one of the two orders within the Myodocopa, in turn a subclass of the ostracods. Like their relatives in the order Myodocopida, they have a long exopod on the second antenna. However, unlike myodocopids, their fifth appendage ... which contains seven genera and one subfamily.

Humphreysella
''Humphreysella'' is a genus of ostracods within the family Thaumatocyprididae ''Thaumatocyprididae'' is a family of ostracods in the order Halocyprida The Halocyprida is one of the two orders within the Myodocopa, in turn a subclass of the ostracods. Like their relatives in the order Myodocopida, they have a long exopo ..., containing 11 species. Members of this genus are filter feeders, and can range from sizes of .5 to 32 millimeters in length. Species The following species are recognised in the genus ''Humphreysella'': * '' Humphreysella bahamensis'' (Kornicker & Iliffe, 1989) * '' Humphreysella baltanasi'' (Kornicker in Humphreys, Kornicker & Danielopol, 2009) * '' Humphreysella elizabethae'' (Kornicker & Iliffe, 1992) * '' Humphreysella exuma'' (Kornicker & Iliffe, 1998) * '' Humphreysella kakuki'' (Kornicker & Iliffe, 2000) * '' Humphreysella mexicana'' (Kornicker & Iliffe, 1989) * '' Humphreysella orghidani'' (Danielopol, 1972) * '' Humphreysella palmeri'' (Korni ...

Ostracod
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 70,000 species (only 13,000 of which are extant) have been identified, grouped into several orders. They are small crustaceans, typically around in size, but varying from in the case of '' Gigantocypris''. Their bodies are flattened from side to side and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on gross morphology. While early work indicated the group may not be monophyletic and early molecular phylogeny was ambiguous on this front, recent combined analyses of molecular and morphological data found support for monophyly in analyses with broadest taxon sampling. Ecologically, marine ostracods can be part of the zooplankton or (most commonly) are part of the benthos, living on or inside the upper layer of the sea floor. While Myod ...

Like their relatives in the order Myodocopida, they have a long exopod on the second antenna. However, unlike myodocopids, their fifth appendage is leg-like rather than modified for feeding, their seventh limb is reduced or absent, and they have no lateral eyes. The group is primarily planktonic. There are two suborders: Halocypridina and Cladocopina.

Lopingian Epoch
The Lopingian is the uppermost series/last epoch of the Permian. It is the last epoch of the Paleozoic. The Lopingian was preceded by the Guadalupian and followed by the Early Triassic. The Lopingian is often synonymous with the informal terms late Permian or upper Permian. The name was introduced by Amadeus William Grabau in 1931 and derives from Leping, Jiangxi in China. It consists of two stages/ages. The earlier is the Wuchiapingian and the later is the Changhsingian. The International Chronostratigraphic Chart (v2018/07) provides a numerical age of 259.1 ±0.5 Ma. If a Global Boundary Stratotype Section and Point (GSSP) has been approved, the lower boundary of the earliest stage determines numerical age of an epoch. The GSSP for the Wuchiapingian has a numerical age of 259.8 ± 0.4 Ma. Evidence from Milankovitch cycles suggests that the length of an Earth day during this epoch was approximately 22 hours. The Lopingian ended with the Permian–Triassic extincti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
