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 ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falco (genus)
Falcons () are birds of prey in the genus ''Falco'', which includes about 40 species. Some small species of falcons with long, narrow bird wing, wings are called hobby (bird), hobbies, and some that hover (behaviour)#Wind hoverers, hover while hunting are called kestrels. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a wikt:broadwing, broadwing. This makes flying easier while still learning the aerial skills required to be effective hunters like the adults. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which also includes two other subfamilies comprising caracara (subfamily), caracaras and ...

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that is, during the Late Miocene.

Bulgaria
Bulgaria, officially the Republic of Bulgaria, is a country in Southeast Europe. It is situated on the eastern portion of the Balkans directly south of the Danube river and west of the Black Sea. Bulgaria is bordered by Greece and Turkey to the south, Serbia and North Macedonia to the west, and Romania to the north. It covers a territory of and is the tenth largest within the European Union and the List of European countries by area, sixteenth-largest country in Europe by area. Sofia is the nation's capital and List of cities and towns in Bulgaria, largest city; other major cities include Burgas, Plovdiv, and Varna, Bulgaria, Varna. One of the earliest societies in the lands of modern-day Bulgaria was the Karanovo culture (6,500 BC). In the 6th to 3rd century BC, the region was a battleground for ancient Thracians, Persians, Celts and Ancient Macedonians, Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acta Zoologica Bulgarica
''Acta Zoologica Bulgarica'' is a peer-reviewed scientific journal publishing original research studies in the fields of animal taxonomy, biogeography and ecology. The journal provides online access to abstracts since 2005 and to articles since 2011. Most articles focus on the Bulgarian and Balkan fauna but articles from other geographical areas are also published. Acta Zoologica Bulgarica has also a supplement series (7 supplement have been published till 2014). The journal is abstracted and indexed in Science Citation Index, Journal Citation Reports (impact factor for 2013 is 0.357), Biological Abstracts, BIOSIS Previews, Scopus and Zoological Record ''The Zoological Record'' (''ZR'') is an electronic index of zoological literature that also serves as the unofficial register of scientific names in zoology.

Prehistoric Birds
Late Quaternary prehistoric birds are Bird, avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th century. In other words, this list deals with avian extinctions between Upper Paleolithic, 40,000 BC and AD 1500. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil; as the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their Taxonomy (biology), taxonomic affiliations. Some birds are also known from folk memory, as in the case of Haast's eagle in New Zeala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossils Of Bulgaria
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...
