Gymnure
Gymnures, also called hairy hedgehogs or moonrats, are mammals belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla. Gymnures resemble rats but are not closely related as they are not rodents; they are instead closely related to hedgehogs, which also belong to Erinaceidae. They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews. Description Although the gymnures are more closely related to the hedgehogs, full-grown gymnures superficially resemble large rats, shrews or opossums. The gymnure's body plan is believed to resemble that of the earliest mammals, with a large, toothy head about 1/3 the length of the total body, a naked furless tail for balance and thermoregulatory purposes, and a plantigrade stance. In direct contrast to the closely related hedgehogs, gymnures are not spiny. They also have an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bouldnor Formation
The Bouldnor Formation is a geological formation in the Hampshire Basin of southern England. It is the youngest formation of the Solent Group and was deposited during the uppermost Eocene and lower Oligocene. Stratotype and occurrence The Bouldnor Formation was named after Bouldnor, a small hamlet east of Yarmouth, Isle of Wight. The formation is exposed along ''Bouldnor Cliff'' between Yarmouth and Hamstead occupying the core of the east-southeast-striking ''Bouldnor Syncline''. Yet the stratotype of the formation is found at ''Whitecliff Bay'' on the east side of the Isle of Wight. History The Bouldnor Formation was scientifically established 1985 by A. Insole and B. Daly, who also defined its members. The paleogene strata on the Isle of Wight had already been described in 1853 by Edward Forbes. Forbes was followed in 1921 by H.J.O. White, a geologist from the Geological Survey. Stratigraphy The Bouldnor-Formation is the topmost formation of the Solent Group before ...

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Eulipotyphla
Eulipotyphla (, which means "truly fat and blind") is an order of mammals suggested by molecular methods of phylogenetic reconstruction, which includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members (tenrecs, golden moles, and otter shrews, now in their own order Afrosoricida). Eulipotyphla comprises the hedgehogs and gymnures (family Erinaceidae, formerly also the order Erinaceomorpha), solenodons (family Solenodontidae), the desmans, moles, and shrew-like moles (family Talpidae) and true shrews (family Soricidae). True shrews, talpids and solenodons were formerly grouped in Soricomorpha; however, Soricomorpha has been found to be paraphyletic, since erinaceids are the sister group of shrews, and they are more closely linked to the Carnivora order; (such as cats, dogs, bears, skunks, badgers, etc.). It is the sister clade of Scrotifera; together, they make up Laurasiatheria. Classification * Order Eulipoty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erinaceidae
Erinaceidae is a family in the order Eulipotyphla, consisting of the hedgehogs and moonrats. Until recently, it was assigned to the order Erinaceomorpha, which has been subsumed with the paraphyletic Soricomorpha into Eulipotyphla. Eulipotyphla has been shown to be monophyletic; Soricomorpha is paraphyletic because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs. Erinaceidae contains the well-known hedgehogs (subfamily Erinaceinae) of Eurasia and Africa and the gymnures or moonrats (subfamily Galericinae) of South-east Asia. This family was once considered part of the order Insectivora, but that polyphyletic order is now considered defunct. Characteristics Erinaceids are generally shrew-like in form, with long snouts and short tails. They are, however, much larger than shrews, ranging from in body length and in weight, in the case of the short-tailed gymnure, up to and in the moonrat. All but one species have five toes in eac ...

Erinaceus
''Erinaceus'' is a genus of hedgehog from the family of Erinaceidae. There are four main species of ''Erinaceus''. The range is all across Europe, throughout the Middle East, parts of Russia, and extending to northern China and Korea. The European hedgehog (''Erinaceus europaeus'') has been introduced to New Zealand.Macdonald, David W. The Encyclopedia of Mammals. New York, NY: Facts on File, 1984 . Description As is characteristic of other hedgehogs, members of ''Erinaceus'' have spines. These spines are a modification of the hair that is formed and strengthened by keratin. They contain hollow air filled gaps separated by thin inner layers of the spine to lessen the weight load.Grzimek, Bernhard, Neil Schlager, Donna Olendorf, and Melissa C. McDade. Grzimek's Animal Life Encyclopedia. Vol. 13. Detroit: Thomson Gale, 2004. Every spine is tapered at the end to form a point and also at the base where it then forms a bulb that is attached to the skin. The tapering at the base allo ...

Henri Filhol
Henri Filhol Henri Filhol (13 May 1843 – 28 April 1902) was a French medical doctor, malacologist and naturalist born in Toulouse. He was the son of Édouard Filhol (1814-1883), curator of the Muséum de Toulouse. After receiving his early education in Toulouse, he moved to Paris, where he obtained doctorates in medicine and science. In 1879 he was appointed professor of zoology at the Faculty of Toulouse. From 1894 to 1902 he occupied the chair of comparative animal anatomy at the ''Muséum national d'Histoire naturelle'' in Paris. In 1897 he became a member of the ''Académie des sciences''. In the field of paleontology, he performed important studies of fossilized mammals in the phosphorites in Quercy.Henri Filhol (1843-1902)- Gloubik Sciences. He served as the expedition doctor and naturalist on the French 1874 Transit of Venus Expedition to Campbell Island, with Filhol Peak on the island being named after him.Tee, Garry JScience on the Map: Places in New Zealand Named A ...

Gomphotherium
''Gomphotherium'' (; "welded beast") is an extinct genus of proboscids from the Neogene and early Pleistocene of Eurasia, Africa, North America and Asia. As of 2021, two species, ''G. annectens'' and possibly ''G. subtapiroideum'', are also known from North Korea. Description Most species of ''Gomphotherium'' were similar in size to the Asian elephant, with ''G. productum'' (known from a 35-year-old male) measuring tall and weighing . The largest species ''G. steinheimense'', known from a complete 37-year-old male found in Mühldorf, Germany, measured up to tall and weighed . It had four tusks, two on the upper jaw and two on the elongated lower jaw. The lower tusks are parallel and shaped like a shovel and were probably used for digging up food from mud. Unlike modern elephants, the upper tusks were covered by a layer of enamel. Compared to elephants, the skull was more elongated and low, indicating that the animal had a short trunk with poor flexibility. These animals ...
