Anisosiren was an early sea cow from the Middle Eocene of Hungary.
Fossils of Anisosiren are known from the Eocene deposits in Hungary. [1] [2]
The Eocene Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name Eocene comes from the Ancient Greek ἠώς and καινός and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.
The Sirenia, commonly referred to as sea-cows or sirenians, are an order of fully aquatic, herbivorous mammals that inhabit swamps, rivers, estuaries, marine wetlands, and coastal marine waters. The Sirenia currently comprise two distinct families: Dugongidae and Trichechidae with a total of four species. The Protosirenidae and Prorastomidae families are extinct. Sirenians are classified in the clade Paenungulata, alongside the elephants and the hyraxes, and evolved in the Eocene 50 million years ago (mya). The Dugongidae diverged from the Trichechidae in the late Eocene or early Oligocene.
Dugongidae is a family in the order of Sirenia. The family has one surviving species, the dugong, one recently extinct species, Steller's sea cow, and a number of extinct genera known from fossil records.
Moeritherium is an extinct genus of primitive proboscideans. These prehistoric mammals are related to the elephant and, more distantly, sea cows and hyraxes. They lived during the Eocene epoch.
Wādī al-Ḥītān is a paleontological site in the Faiyum Governorate of Egypt, some 150 kilometres (93 mi) south-west of Cairo. It was designated a UNESCO World Heritage Site in July 2005 for its hundreds of fossils of some of the earliest forms of whale, the archaeoceti. The site reveals evidence for the explanation of one of the greatest mysteries of the evolution of whales: the emergence of the whale as an ocean-going mammal from a previous life as a land-based animal. No other place in the world yields the number, concentration and quality of such fossils, as is their accessibility and setting in an attractive and protected landscape. The valley was therefore inscribed on the UNESCO World Heritage List in 2005.
Sirenia is the order of placental mammals which comprises modern "sea cows" and their extinct relatives. They are the only extant herbivorous marine mammals and the only group of herbivorous mammals to have become completely aquatic. Sirenians are thought to have a 50-million-year-old fossil record. They attained modest diversity during the Oligocene and Miocene, but have since declined as a result of climatic cooling, oceanographic changes, and human interference. Two genera and four species are extant: Trichechus, which includes the three species of manatee that live along the Atlantic coasts and in rivers and coastlines of the Americas and western Africa, and Dugong, which is found in the Indian and Pacific oceans.
Athene is a genus of owls, containing nine living species, depending on classification. These birds are small, with brown and white speckles, yellow eyes, and white eyebrows. This genus is found on all continents except for Australia, Antarctica, and Subsaharan Africa. An evolutionary radiation of 4 species is also present in the Solomon Islands.
The Fur Formation is a marine geological formation of Ypresian age which crops out in the Limfjord region of Denmark from Silstrup via Mors and Fur to Ertebølle, and can be seen in many cliffs and quarries in the area. The Diatomite Cliffs is on the Danish list of tentative candidates for World Heritage and may become a world Heritage site.
Eotheroides is an extinct genus of Eocene sirenian. It is an early member of the family Dugongidae, which includes the extant dugong. Fossils have been found from Egypt, India, and Madagascar. Eotheroides was first described by Richard Owen in 1875 under the name Eotherium, which was replaced by the current name in 1899.
Lithornis is a genus of extinct paleognathous birds. Lithornis were able to fly well, but are closely related to today's tinamous and ratites.
Protosiren is an extinct early genus of the order Sirenia. Protosiren existed throughout the Lutetian to Priabonian stages of the Middle Eocene. Fossils have been found in the far-flung locations like the United States, Africa (Egypt), Europe and Asia.
Samu is the nickname given to a fragmentary human occipital bone found in Vértesszőlős, Central Transdanubia, Hungary. The discovery was made on 21 August 1965 during a dig led by László Vértes, and the fossil was named Sámuel, 21 August being the name day of biblical judge Samuel in Hungarian tradition. It has since become widely known as Samu, a Hungarian short form of the name.
The Mecsek Coal Formation is a Jurassic geologic formation in Hungary. Indeterminate fossil ornithischian tracks have been reported from the formation.
Paschatherium is a small extinct mammal of the Perissodactyla order, with an insectivore-like dentition. Its morphology indicates an arboreal form, adapted climbing and running on trees. Paschatherium must have been extremely numerous in the latest Paleocene and earliest Eocene of Europe, since it makes up the majority of all mammal fossils in some fossil sites.
Egypt has many fossil-bearing geologic formations, in which many dinosaurs have been discovered.
Eosiren is an extinct genus of sea cow that lived during the Late Eocene to Early Oligocene (Rupelian). Several fossils have been found in Egypt. It seems like the species E. abeli were contemporaneous with Protosiren and Eotheroides. like them, Eosiren closely resembled modern sirenians. It differes from them by having somewhat larger innominates and possess thigh bones.
Anapithecus is a late Miocene primate known from fossil locations in Hungary and Austria. Many Anapithecus fossils come from the site of Rudabánya, in northern Hungary, where Anapithecus lived alongside the ape Rudapithecus. The only species in the genus, Anapithecus hernyaki, is named after Gabor Hernyák, chief geologist of the Iron Ore Works of Rudabánya.
Rudapithecus is a chimpanzee-like genus of ape which inhabited Europe during the Late Miocene, approximately 10 million years ago. One species is known, Rudapithecus hungaricus. The genus name "Rudapithecus" comes from where it was discovered, in Rudabánya, Northern Hungary. The specific name "hungaricus" refers to the country where it was discovered, in Hungary.
Paralitherium was an early sea cow from the late Eocene of Hungary (Felsotarkany).
Sirenavus was an early sea cow from the Eocene of Hungary.
