Neochen Barbadiana
''Neochen barbadiana'' is an extinct species of goose from the Late Pleistocene of Barbados. The species was described by American paleontologist Pierce Brodkorb from fossils found in Ragged Point, Saint Philip.Brodkorb, P. (1965) Fossil birds from Barbados, West Indies. The Journal of the Barbados Museum and Historical Society 31(1): 3-10. This was the third fossil species of the genus to be described after ''Neochen pugil'' and '' N. debilis'' from Brazil and Argentina Argentina, officially the Argentine Republic, is a country in the southern half of South America. It covers an area of , making it the List of South American countries by area, second-largest country in South America after Brazil, the fourt ..., respectively.

Pistosauroidea
Pistosauroidea is a group of marine reptiles within the superorder (biology), superorder Sauropterygia that first appeared in the latter part of the Early Triassic and were the ancestors of plesiosaurs. Pistosauroids are rare in Triassic marine assemblages, and are represented by only a few fossils from central Europe, the United States, and China. Recent phylogenetic analyses consider the Triassic pistosauroids to be a paraphyletic grouping, meaning that they do not form a true clade. Plesiosauria is now placed within Pistosauroidea, while the traditional pistosauroids are successively more basal (phylogenetics), basal, or primitive, sauropterygians. Below is a cladogram of pistosauroid relationships from Cheng ''et al.''

Chinchenia
''Chinchenia'' is an extinct genus of a basal pistosauroid known from the Middle Triassic (possibly Ladinian age) of Guizhou Province, southwestern China. It contains a single species, ''Chinchenia sungi''. Discovery ''Chinchenia'' is known from at least 4 extremely fragmentary individuals all preserved and collected together. The lectotype of ''Chinchenia'' was chosen to be IVPP V3227, the front end of the left mandible, since that at the time of its original description, its type material was not specified. Other elements from its original description are considered to be paratypes and include the front part of a left lower jaw with 5 broken teeth, 11 neck, six lower back and one sacral vertebrae in various degrees of completeness, 8 unidentified neural arch fragments, many fragments of dorsal and sacral ribs including one proximal part of a left dorsal rib, two right scapulae one of which is very incomplete, two complete humeri, 5 incomplete humeri of which four ar ...

Minerva (bird)
''Minerva'' is an extinct genus of owls in the prehistoric family Protostrigidae from the Eocene of North America. Described in 1915 by R. W. Shufeldt, some of the bones of ''Minerva'' were interpreted as belonging to an edentate mammal by Alexander Wetmore Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution.

Poway Formation
The Poway Group is a geologic group in San Diego County, Southern California. It preserves fossils dating back to the Paleogene period. Poway clasts Volcanic clastic rock cobbles of rhyolite, in a sandstone matrix in this area are named Poway clasts. The ancient Ballena River brought rhyolite-gravel, or "Poway" clasts, from a region in present-day Sonora, Mexico to the Pacific Ocean. Its sediments deposited into an alluvial fan–submarine canyon–submarine fan complex extending for miles offshore. Remnants of submarine fan facies outcrops are found as far west as the northern Channel Islands. Inland Ballena River deposits outcrop discontinuously over in a west-southwest trend from Whale Mountain to San Vicente Reservoir; here, the river was up to in width through the Peninsular Ranges. Stratigraphy Kennedy and Moore (1971) describe a stratigraphy of up to three geologic formations: Stadium Conglomerate, Mission Valley Formation, and the later-named Pomerado Conglomerate ...

Late Eocene
The Priabonian is, in the International Commission on Stratigraphy, ICS's geologic timescale, the latest age (geology), age or the upper stage (stratigraphy), stage of the Eocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. ''Priabona florissantius, Priabona'', an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known. History and naming The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona (Monte di Malo), Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. Stratigraphic definition The base of the Priabonian Stage is at the first appearance datum, first appearance of calcareous nannoplankton species ''Chiasmolithus ...

Phalacrocoracidae
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland, and the names "cormorant" and "shag" have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
