Messelirrisor
The extinct ''Messelirrisor'' is a genus of Bucerotiformes, the sole representative of the family Messelirrisoridae. They were tiny hoopoe-like birds that were the earliest representatives of the hoopoe/ wood-hoopoe lineage, and they were among the predominant small forest birds of Central Europe during the Middle Eocene (some 49-37 mya). Fossilized remains of ''Messelirrisor'' have been found in the Messel Pit of Hesse, Germany Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total popu ....

Bucerotiformes
Bucerotiformes is an order of birds that contains the hornbills, ground hornbills, hoopoes and wood hoopoes. These birds were previously classified as members of Coraciiformes. The clade is distributed in Africa, Asia, Europe and Melanesia Melanesia (, ) is a subregion of Oceania in the southwestern Pacific Ocean. It extends from New Guinea in the west to the Fiji Islands in the east, and includes the Arafura Sea. The region includes the four independent countries of Fiji, Vanu .... Systematics Recent genetic data show that ground hornbills and '' Bycanistes'' form a clade outside the rest of the hornbill lineage. They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia. The hoopoe subspecies Saint Helena hoopoe and the Madagascar subspecies are sometimes elevated to a full species. The two wood hoopoe genera, '' Phoeniculus'' and '' Rhinopomastus'', appear to have diverged about 10 million years ago, so some syste ...

Messel Pit
The Messel Formation is a Formation (geology), geologic formation in Hesse, central Germany, dating back to the Eocene Epoch (geology), epoch (about 47 Ma). Its geographic range is restricted to the Messel pit. There it unconformably overlies crystalline Variscan basement and its Permian cover (Rotliegend) as well as Eocene volcanic breccias derived from the basement rocks. The formation mainly comprises lacustrine laminated bituminous shale (‘oil shale’) renowned for its content of fossils in exceptional preservation, particularly plants, arthropods and vertebrates (e.g. ''Darwinius masillae''). Messel pit The Messel pit () is a disused quarry near the village of Messel (Landkreis Darmstadt-Dieburg, Hesse) about southeast of Frankfurt am Main, Germany. Bituminous shale was mined there. Because of its abundance of well-preserved fossils of the Messel Formation dating from the middle of the Eocene, it has significant geological and scientific importance. Over 1400 taxa o ...

Hoopoe
Hoopoes () are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "Crest (feathers), crown" of feathers which can be raised or lowered at will. Two living and one extinct species are recognized, though for many years both extant species were lumped as a single species—''Upupa epops''. In fact, some taxonomists still consider the species to be Biological_specificity#Conspecific, conspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on the IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round. Taxonomy The genus ''Upupa'' was introduced in 1758 by the Swedish naturalist Carl ...

Middle Eocene
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', ' Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in ...

Coraciiformes
The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing. The members of this order are linked by their "slamming" behaviour, thrashing their prey onto surfaces to disarm or incapacitate them. In the past, Coraciiformes encompassed all anisodactyl (including syndactyl) members of the Cavitaves. This means that the birds currently classified in Leptosomiformes ( cuckoo-roller) and Bucerotiformes ( hornbills, hoopoes and allies) were formerly classified in Coraciiformes. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means " raven-like". Specifically, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct
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 ...
