Amphechinus
''Amphechinus'' is an extinct genus of hedgehog of the family Erinaceidae, which lived in Asia and Europe during the Oligocene and in North America, Africa, Asia and Europe during the Miocene. The genus contains at least 14 species. It is classified in the subfamily Erinaceinae and in the family Erinaceidae. A single specimen examined in 1998 was estimated to have had a weight of when alive. Characteristics As a member of the family Erinaceidae and in the subfamily Erinaceinae, Amphechinus may have been around the size of the European hedgehog, with males being larger than females. Diet Like many other genera in the family Erinaceidae, Amphechinus mostly ate either small invertebrates like modern day hedgehogs like beetles, worms, caterpillars earwigs and more other insect species and shuffle through the ground to find any insects. Distribution Amphechinus may have either lived in forests and dense areas with enough food sources like caterpillars and other insects to eat ...

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 both Soricidae and Talpidae share a more recent common ancestor with Erinaceidae than with solenodons. Erinaceidae contains the well-known hedgehogs (subfamily Erinaceinae) of Eurasia and Africa and the gymnures or moonrats (subfamily Galericinae) of Southeast 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 ...

Hedgehogs
A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are 17 species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus '' Amphechinus'' was once present in North America. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last 15 million years. Like many of the first mammals, they have adapted to a nocturnal way of life. Their spiny protection resembles that of porcupines, which are rodents, and echidnas, a type of monotreme. Etymology The name ''hedgehog'' came into use around the year 1450, derived from the Middle English , from , , because it frequents hedgerows, and , , from its piglike snout. Other names that are used are ''urchin'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Aymard
Auguste Aymard (5 December 1808 – 26 June 1889) was a French prehistorian and palaeontologist who lived and died in Puy-en-Velay (Haute-Loire). He described the fossil '' Entelodon magnus'' and the fossil genera ''Anancus ''Anancus'' is an extinct genus of "tetralophodont gomphothere" native to Afro-Eurasia, that lived from the Tortonian stage of the late Miocene until its extinction during the Early Pleistocene, roughly from 8.5–2 million years ago. Taxonomy ...'' and '' Amphechinus''. Auguste Aymard was the archivist for the Departement Haute-Loire and Conservateur of Musée du Puy-en-Velay. He made archaeological discoveries in Puy-en-Velay, Polignac, Haute-Loire and Espaly-Saint-Marcel.

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Prehistoric Placental Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Mammals Of North America
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
