Larus Lacus
''Larus lacus'' is an Extinction, extinct species of gull that lived in North America during the Late Pliocene. Etymology The genus name ''Larus'' derives from Ancient Greek, referring to a seabird. The species name ''lacus'' derives from Latin, meaning "lake or standing body of water, in reference to the lagoonal deposits at the type locality." Description ''Larus lacus'' specimens stem from Sarasota County, Florida, Sarasota County, Florida. The humerus of ''Larus lacus'' most closely resembles the Hartlaub's gull (''Chroicocephalus hartlaubii'', formerly ''Larus hartlaubii''), black-headed gull (''Chroicocephalus ridibundus''; formerly ''Larus ridibundus''), brown-hooded gull (''Chroicocephalus maculipennis''; formerly ''Larus maculipennis''), and Franklin's gull (''Leucophaeus pipixcan''; formerly ''Larus pipixcan'').

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 ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Gull
Gulls, or colloquially seagulls, are seabirds of the subfamily Larinae. They are most closely related to terns and skimmers, distantly related to auks, and even more distantly related to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews; this still exists in certain regional English dialects and is cognate with German , Danish ', Swedish ', Dutch ', Norwegian ', and French '. Gulls are usually grey or white, often with black markings on the head or wings. They normally have harsh wailing or squawking calls, stout bills, and webbed feet. Most gulls are ground-nesting piscivores or carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustaceans, molluscs, fish and small birds. Gulls have unhinging jaws that provide the flexibility to consume large ...

Larus
''Larus'' is a large genus of gulls with worldwide distribution (by far the greatest species diversity is in the Northern Hemisphere). Many of its species are abundant and well-known birds in their ranges. Until about 2005–2007, most gulls were placed in this genus, but this arrangement is now known to be polyphyletic, leading to the resurrection of the genera ''Chroicocephalus'', ''Ichthyaetus'', ''Hydrocoloeus'', and ''Leucophaeus'' for many other species formerly included in ''Larus''. They are in general medium-large birds, typically pale grey to black above and white below and on the head, often with black markings with white spots ("mirrors") on their wingtips and in a few species also some black on the tail. They have stout, longish beak, bills and webbed feet; in winter, the head is often streaked or smudged dark grey. The young birds are brown, and take three to five years to reach adult plumage, with subadult plumages intermediate between the young and adult. The ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hartlaub's Gull
Hartlaub's gull (''Chroicocephalus hartlaubii'') is a small gull in the genus ''Chroicocephalus''. It was formerly (as with other related gulls) placed in the genus ''Larus'' until genetic research demonstrated that the old broad view of that genus was paraphyly, paraphyletic. In the past it had sometimes been treated as a subspecies of the Australasian silver gull (''C. novaehollandiae''), but is now treated as a separate species; current genetic evidence suggests its closest relative is not the silver gull but the African and South American grey-headed gull (''C. cirrocephalus''), and in particular the African subspecies of it ''C. c. poiocephalus'' (with the possibility that ''C. cirrocephalus'' is paraphyletic with respect to ''C. hartlaubii'': Černý & Natale 2022, Fig. 6). The species' name commemorates the German physician and zoologist, Gustav Hartlaub. In the past, it was also sometimes known as "king gull". Description Hartlaub's gull is 37–39 cm in length, wit ...

Black-headed Gull
The black-headed gull (''Chroicocephalus ridibundus'') is a small gull that breeds in much of the Palearctic in Europe and Asia, and also locally in smaller numbers in coastal eastern Canada. Most of the population is migratory and winters further south, but many also remain in the milder areas of northwestern Europe. It was formerly sometimes cited as "common black-headed gull" to distinguish it from "great black-headed gull" (an old name for Pallas's gull). The genus name ''Chroicocephalus'' is from the Ancient Greek words ''khroizo'', "to colour", and ''kephale'', "head". The specific name ''ridibundus'' is Latin for "laughing". Taxonomy The black-headed gull was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his ''Systema Naturae''. He placed it with the other gulls in the genus ''Larus'' and coined the binomial name ''Larus ridibundus''. Linnaeus specified the locality as ''Mari Europaeo'' or European seas. Genetic stud ...

Brown-hooded Gull
The brown-hooded gull (''Chroicocephalus maculipennis'') is a species of gull, found in South America in Argentina, southeastern Brazil, Chile, Uruguay, and in the South Atlantic Ocean on the Falkland Islands. Its specific epithet, '' maculipennis'', means 'spotted wings' (''macula'' + ''penna''). Like the other species of the genus ''Chroicocephalus'', it was formerly included in a broad view of the genus ''Larus''. Description Adults in the breeding season have a dark brown head and throat with a white semicircle around the posterior of the eye, while the neck, chest and abdomen are white. In winter plumage, the brown hood is largely lost, retaining just a dark spot behind the eye and a dark smudge around the eye. The beak and legs are red, and the eye is dark brown. The outer primary flight feathers are white with black tips (the 'spots' of the scientific name) above and showing more extensively black from below, while the inner primaries and the secondaries and covert feath ...

Franklin's Gull
Franklin's gull (''Leucophaeus pipixcan'') is a small (length 12.6–14.2 in, 32–36 cm) gull. The genus name ''Leucophaeus'' is from Ancient Greek ''leukos'', "white", and ''phaios'', "dusky". The specific ''pipixcan'' is a Nahuatl name for a type of gull. The English common name was given to commemorate the arctic explorer Sir John Franklin, who led an expedition in 1825 on which the type was collected. Description It breeds in central provinces of Canada and adjacent states of the northern United States. It is a migratory bird, wintering in Argentina, the Caribbean, Chile, and Peru. The summer adult's body is white and its back and wings are much darker grey than all other gulls of similar size except the larger laughing gull. The wings have black tips with an adjacent white band. The bill and legs are red. The black hood of the breeding adult is mostly lost in winter. Young birds are similar to the adult but have less developed hoods and lack the white wing band. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
